From imbalanced data on students in poverty, the traditional machine learning algorithm is biased towards the majority classes in classifying, which leads to inaccuracy of high-needs student classes. A classification method was tailored for impoverished students based on cost-sensitivity. First, a feature selection-based preprocessing method was employed to address the low quality data. Then, the optimal cost-sensitive matrix was determined by the search method based on genetic algorithm. Finally, the preprocessing data were used to train a cost-sensitive classifier for minority classes with reduced impact of the majority class. Multiple datasets of actual impoverished students in Guangxi was wsed to conduct comparative experiments. With the CART algorithm as the baseline, the average overall accuracy of this method shoas a floating value of 0. 66%. The average accuracy improvement of minority classes is 6. 3%, and the highest improvement can reach 14. 7%. The results show that the proposed method can improve the accuracy of student classification with accuracy. [ABSTRACT FROM AUTHOR]

[Purpose/Significance] With the improvement of China's urbanization level, a large number of migrant workers have entered the city to seek development. This article analyzes the hot topics and research frontiers in the field of migrant workers, which helps to clarify the research status and frontier trends in the field of migrant workers. [Methods/Process] We conducted descriptive statistics and visual analysis of the literature related to migrant workers in CSSCI journals from 2010 to July 2020, the distribution of key authors and the source of the publishing organization, and the source of the key words with the help of CiteSpace tools. [Results/Conclusions] The research found that the research hotspots in the field of migrant workers in the past ten years mainly include: new generation migrant workers, migrant workers' children, migrant workers' urban integration, migrant workers' social security, migrant workers related influencing factors and countermeasures research; The latest research frontiers in the field mainly focus on targeted poverty alleviation, happiness, citizenship willingness, migrant workers' entrepreneurship, career development, and mental health. In addition, the teachers and students of various universities are the main force in the research of the migrant worker group at this stage, but the universities lack long-term large-scale cooperation, only a small amount of internal cooperation, and cross-institutional cooperation research is rare. In the future, we can strengthen cross-institutional and cross-field cooperative research; improve the policy and regulation system for migrant workers, protect their basic rights and interests in employment, education, health and medical care, improve the social service system, and promote social equity and stability.

(1)Background--In Yunnan Province, the poverty problem is serious, and the available poverty alleviation resources are limited. The under-forest industry plays an important role in achieving the goal of poverty alleviation. However, there are few researches on the poverty alleviation effect of under-forest industry. (2)Methods--In this paper, the semi-structured interview method is used to discuss with relevant cadres, who are the forestry department (bureau), Poverty Alleviation Office, village committee, etc. of Sanhe Village in Lushui City, so as to make clear the development of under-forest industry and the situation of poverty alleviation and development in Sanhe Village. In addition, in August 2018, the members of the investigation team went to Sanhe Village, Lushui city to carry out field investigation, and a total of 150 questionnaires were issued and 139 were recovered, with an effective rate of 92. 7%. (3)Results--First of all, forest farmers in Sanhe Village have a high enthusiasm to develop the undergrowth industry, 79. 6% are willing to expand the scale of the forest industry, and 56. 1% are optimistic about the development of the forest industry, but in the process of developing the forest industry, 51. 6% of them would encounter economic and technological difficulties. Secondly, the farmers are familiar with the cooperative, and most of them have joined the cooperative. 60. 8% of the farmers enjoy the technology, production and loan services provided, while 57. 8% of the farmers want the cooperative to provide technical guidance, financial support and other services. However, 55. 1% of forest farmers did not understand the entry of enterprises, and the business model of enterprise cooperation was relatively single, and the help mainly focused on the market and technology. In addition, 77. 6% of the forest farmers are willing to accept the relevant skills training, and 73. 5% of the forest farmers are satisfied with the effect of the skills training, but 40. 8% of the forest farmers have not participated in all kinds of skills training, the degree of personal attention is an important factor influencing farmers' active participation in training. Finally, The development of the forest industry has effectively promoted the economic development of the poor areas, improved the infrastructure construction of the forest area, and improved the ecological environment of Sanhe Village. (4)Conclusions and Discussions--The forest farmers in Sanhe Village are more active in the development of forest economy, but they'd like to encounter difficulties in capital and technology. In addition, the proportion of forest farmers participating in cooperatives is high, and cooperatives provide services, but the rate of enterprises settling in is low. Furthermore, forest farmers are willing to accept skills training, and they are more satisfied with the training effect, and they tend to accept technical and management training. In Sanhe Village, remarkable results have been achieved in poverty alleviation by forest industry, which has effectively promoted the economic development of poverty-stricken areas. Based on the problems encountered in the development of forest industry in Sanhe Village and the actual situation of poverty alleviation and development, the following suggestions are put forward: First, the government should scientific planning and active guidance. Second, the enterprises or cooperatives should strengthen the publicity and provide skills training. Third, farmers should change the thinking of forest farmers and take the initiative to develop under-forest industry. [ABSTRACT FROM AUTHOR]

Potato is the main crop and important pillar industry in poor mountainous areas of the Yunnan-Guizhou Plateau and the Loess Plateau in China. At present, there are several key common problems in potato production in these two regions, such as high incidence of diseases and insect pests, high chemical fertilizer usage but low utilization efficiency, imperfect seed potato breeding system and narrow market, which seriously restrict the sustainable development of potato industry. Taking Zhaotong of Yunnan Province and Dingxi of Gansu Province as examples, this study analyzes the advantages and necessity of developing seed potato industry in plateau poverty-stricken areas from the perspectives of ecological characteristics, location advantages and targeted poverty alleviation. It is proposed that the promotion of disease-resistant varieties, the introduction of green and efficient fertilizer application and pest control technologies, the establishment of specialized seed potato breeding technology system and large-scale base, as well as the expansion of seed potato market are effective measures for implementing poverty alleviation in the plateau regions.

After the elimination of absolute poverty by 2020 in China, consolidating the achievements of targeted poverty alleviation, reducing relative poverty, and promoting rural revitalization will become the key tasks of poverty alleviation and development in the future. This paper reviews the basic logic of the major policies of poverty alleviation and rural revitalization, analyzes the importance and necessity of consolidating the achievements of poverty alleviation in the new stage, and puts forward the main ideas and key contents of consolidating the achievements of poverty alleviation. It is suggested that we should continue to adhere to the idea of "precision" and establish the bottom line thinking of eliminating absolute poverty. We will consolidate the achievements we have made in poverty alleviation by promoting the institutionalization of poverty alleviation, ensuring the sustainable development of poverty alleviation industries, expanding channels for increasing the incomes of people lifted out of poverty, improving supporting facilities for the relocation of poor people from inhospitable areas, and raising the level of security for those in need. And expanding the achievements of poverty alleviation in line with the rural industry revitalization, living environment renovation, people's livelihood security improvement and rural civilization construction, so as to create a new pattern of coordinated progresses in poverty alleviation and rural revitalization.

China put forward the major strategy of targeted poverty alleviation in 2013, and implemented the "most stringent assessment and evaluation" system to ensure that the work of poverty alleviation is pragmatic, the process of poverty alleviation is solid and the result of poverty alleviation is real. Targeted poverty alleviation assessment is an important means to improve the effectiveness of national targeted poverty alleviation, which is of great significance to fight against poverty alleviation and promote the modernization of national governance system and governance capacity. Based on the practice of the third-party evaluation of the effectiveness of national targeted poverty alleviation, this paper discusses the differentiation law of rural poverty and its scientific cognition, summarizes the theory and technology system of national targeted poverty alleviation evaluation, and deeply analyzes the application and contribution of evaluation theory and technology in the evaluation survey over the years. Results show that the "island effect" and "marginal diminishing effect" of rural poverty, and the supply-demand structure between the government's "support" and the farmers' "poverty" are the scientific significance of implementing the effectiveness assessment of targeted poverty alleviation. They require in-depth assessment to promote rectification and effectively improve the performance of targeted poverty alleviation. The theoretical cognition and practical needs of rural poverty are the important basis for establishing assessment objectives and developing assessment plan, and plays a direct guiding role in refining the assessment indicators of antipoverty effectiveness, exploring the connotation of indicators and formulating evaluation work plans. Theoretical system of national third-party assessment on the effectiveness of targeted poverty alleviation is a comprehensive system including key technologies, supporting technologies, package support system, and big data platform. It has successfully supported the national effectiveness assessment of targeted poverty alleviation from 2016 to 2020, and has played the role of "baton", "quality inspection instrument", and "propeller", providing references for the assessment and scientific decision-making for poverty alleviation.

Industrial assistance is one of the most important parts of targeted poverty alleviation, the impact of poverty identification and targeted assistance on the efficiency of poverty alleviation industry is worth of further study. Based on the survey data of 534 farmers in Shizhu Tujia Autonomous county, Chongqing, this paper applied the classical statistical analysis framework to test the differences in planting industry efficiency between villages and farmers after poverty identification, and further explored the formation of differences. The results show that: (1) Poverty identification and targeted assistance significantly promote the efficiency of the planting industry, especially in the poverty- stricken villages and the poor households. (2) The policy is the key factor that causes significant differences in planting efficiency between poor and non- poor villages and households. Among them, infrastructure construction such as road construction, and characteristic planting industries have a particularly strong impact on poverty- stricken villages and poor households. (3) The effect of age on the efficiency of the planting industry in poverty-stricken areas shows a "U- shaped" pattern, in which 55 to 60 years old is an efficiency turning point. (4) Farmers with high school education and above can promote the efficiency of the planting industry. Therefore, in order to resolve the unbalanced contradictory problem, the local governments should continue to implement industrial assistance policies and establish a long-term mechanism to ensure the steady growth of poor people's income, and improve the agricultural labor force in poverty-stricken areas, as well as increase the level of human capital.

As an essential way to maintain social equity, school-supplied meal programs are widely implemented in countries around the world. In 1964, the congress of America enacted the National School Lunch Act( NSLA), declaring school lunch program as a measure of national security and providing it with legislative guarantee. After two significant revisions, the current qualification methods have been established. In this paper, the author analyses the eligibility requirements in the NSLA on state level, school level and student level, respectively, in order to provide targeted suggestions for Chinese school meal programs and alleviate poverty precisely.

Eco- compensation is an important policy of ecological construction and environmental protection in China. Targeted poverty alleviation is also a significant measure to promote regional coordinated development and ensure that impoverished people can get rid of poverty on schedule. There are some coupling points between the two, such as objects, subjects, carriers, standards, ways and means. China has put forward "a set of poverty alleviation through eco- compensation". Many regions, in light of their actual situations, have also carried out relevant works by combining eco- compensation with targeted poverty alleviation. At present, there are some connections and coupling developments between targeted poverty alleviation and eco- compensation in China. The five typical coupling developments are shown in the following. (1) Coupling development between poor population and eco- compensation object. For the poor people with labor capacity, the government will employ them as forest rangers. As for the targets of poverty alleviation, they will be directly included in the scope of preferential policies of eco-compensation funds and receive subsidies under eco- compensation policies. (2) Coupling development between poverty alleviation region and eco- compensation area. In China, most of the poverty- stricken areas, such as concentrated areas with special difficulties, key counties for poverty alleviation and development, and poverty stricken villages, are distributed in ecologically fragile areas whose ecosystems are sensitive and need to be protected. (3) Coupling development between poverty alleviation industry and eco-compensation measure. The local governments guide the poor to realize green transfer of production, help the impoverished villages to adjust and optimize their industrial structure and transform the mode of economic development, train the impoverished households in planting and raising, and help them to develop special industries such as rural forest tourism, famous and special cash crops, farm recreation, and under-forest economy. (4) Coupling development between poverty intensity and eco-compensation standard. In China, we have implemented regional differential compensation policies, such as appropriately raising eco- compensation standards for poverty stricken villages and poor households, raising subsidies for ecological public welfare forests, and increasing the salaries of forest rangers, etc. In some regions, when determining the key poverty alleviation targets, we, in addition to considering poverty factors such as economic income, should also figure out whether these poverty alleviation targets undertake ecological construction tasks, such as ecological public welfare forest protection, and finally determine the corresponding compensation standards based on their ecological contribution. (5) Coupling development between poverty alleviation policy and eco-compensation requirement. In defining the object of poverty alleviation, priority should be given to the impoverished population who bear the task of public forest protection. In the arrangement of poverty alleviation funds and development funds, such as subsidies for returning farmland to forests and subsidies for under- forest economy arranged by various sectors, are preferentially inclined to the poorer households under the same conditions. In the key areas of poverty alleviation, priorities should be given to the fields of ecological environment construction and protection, the ecological industry development, and some other aspects which are closely related to eco-compensation policies. Each has its own connotation and characteristics. In order to further promote the coupling development between targeted poverty alleviation and eco- compensation in China, we can take measures in many aspects, such as strengthening theoretical researches, clearing the direction and focus of coupling, consolidating the public foundation, and innovating the development model.

Sustainable land use, urban/town development and targeted poverty alleviation are key issues for poverty- stricken border counties. This paper explored the spatial and temporal characteristics and driving forces of construction land change in Longzhou, a typical povertystricken border county in Southwest China based on high-resolution images of 2011 and 2016 from Google Earth. Both qualitative and quantitative analyses were employed. The results showed that: Firstly, the construction land increased by 10.08% during 2011- 2016, and the areal proportion of construction land in Longzhou County increased from 2.20% to 2.42% during 2011- 2016. The increments of urban construction land, rural residential land, independent industrial and mining land, construction land for traffic and construction land for tourist facilities accounted for 37.74% , 25.48% , 20.96% , 15.49% and 0.33% of the total increment of construction land, respectively. Secondly, construction land increased more significantly in the county town of Longzhou, Shanglong Town, which is near the county town, and Shuikou Town which is the most important trade port of Longzhou, than in the other towns. Thirdly, speeded-up urban development, rural housing construction, construction of industrial parks and transportation facilities are the most important direct factors driving the expansion of construction land. Fourthly, the construction land expansion is infilling expansion in the county town while it is edge-expansion in the other towns. Meanwhile, the implementation of targeted poverty alleviation strategy and the booming of border trade activities are important policy drivers. This paper suggests that local government should fully use the preferential policies of construction land for poverty-stricken counties issued by the central government. [ABSTRACT FROM AUTHOR]
