In order to explore the technical methods to improve the ecological carrying capacity of regional land under the premise of limited land use area, an open ecological footprint model is established based on the traditional ecological footprint model. Using the two models, this paper evaluates the ecological carrying capacity of Henan Province in 2017. The results indicate that the ecological productive footprint of cultivated land in Henan Province is much larger than the ecological carrying capacity, but the ecological consumption footprint is lower than the ecological carrying capacity. The open ecological footprint model can clearly distinguish the internal and the external ecological consumption footprint after corrected by the consumption adjustment coefficient and the land-use structure adjustment coefficient. Based on the open ecological footprint model, the ecological carrying capacity evaluation results of Henan Province are more realistic. The comprehensive ecological carrying capacity in Henan Province has a surplus, but there are significant differences among different land use types. The cultivated land has the largest ecological carrying capacity surplus, while the fossil energy land has a larger ecological carrying capacity deficit. In the process of achieving sustainable development, Henan Province should focus on reducing energy consumption and improving the ecological carrying capacity of fossil energy land. The paper concludes that the open ecological footprint model can simulate the ecological carrying capacity under different land use structures and different consumption structures. According to the simulation results, the technical methods to improve the ecological carrying capacity under the premise of limited land use scale can be proposed. The research can provide reference for land use structure adjustment, land use planning and land protection in Henan Province. It can also provide scientific basis for ecological protection and high-quality development of the Yellow River basin. [ABSTRACT FROM AUTHOR]

Using meteorological data of Anhui Meteorological Bureau, based on the multi-level fuzzy comprehensive analysis method, this paper preliminarily explores the main types and various influencing factors of regional meteorological disasters related to hotel buildings in the Dabie Mountain Scenic Area, and puts forward suggestions on how to deal with the risk of meteorological disasters in the scenic area, in order to provide a better understanding of the Dabie Mountains. It provides a theoretical basis for better response to meteorological disaster decision-making in the development of the scenic spot, and also hopes to provide reference for other Dabie Mountain scenic spots in Hubei and Henan. The research results show that the main types of meteorological disasters faced by hotel buildings in the Dabie Mountain Scenic Area are; rainstorm, thunder and lightning, heavy fog, and snow disaster. The occurrence frequency of various disasters is higher than that of the plains, and the intensity is higher. Due to the high altitude of the hotel buildings, the soil resistivity has obvious mutation or stratification. The terrain surrounded by mountains on three sides often becomes a good conductor of lightning, and the risk of lightning strikes is high, and the lighting weather is frequent. The Dabie Mountain Scenic Area is prone to heavy fog, frost, snow disaster and other weather due to its high altitude, high air humidity and low temperature. Hotels in the Dabie Mountain Scenic Area should effectively deal with meteorological disasters and reduce losses by formulating disaster prevention plans, strengthening lightning protection engineering measures for hotel buildings, and regularly testing and maintaining the lightning protection devices installed in hotels.

Residents' payment is an important supplement to the government's urban haze control costs. In this paper, Zhengzhou City and Jiaozuo City of Henan Province were taken as research objects. Through research methods such as data mining, questionnaire survey and model construction, the residents' cognition on haze control, willingness to pay and its influencing factors were deeply studied. Main research results were as below; residents in Zhengzhou and Jiaozuo have improved their awareness and satisfaction with haze control, but the growth rate was slow. In 2014, 2018 and 2021, the expected values of willingness to pay for haze control in Zhengzhou were 79.94, 85. 52 and 47.20 yuan/month respectively, while they were 62. 17, 57.77 and 46. 96 yuan/month in Jiaozuo City. Residents' haze awareness had the most significant effect on the willingness to pay for haze control, and there was positive correlation (P <0.05). Residents' cognition of haze control was the most important factor affecting their willingness to pay for haze control. Residents' income level and air pollution level had a positive effect on residents' willingness to pay, while residents' confidence in the government had a weak impact on their willingness to pay.

[Objective] The paper was to study the relationship between spatial distribution characteristics of soil pH and bacterial wilt in tobacco-growing area in Henan Province. [Method] The 21 tobacco-growing fields infected by bacterial wilt and 91 tobacco-growing fields with no cases were selected from Henan Province, and the pH of fields was determined. [Result] Bacterial wilt mainly occurred in the tobacco-growing fields in Luoshan, Pingqiao, Queshan, Biyang, Suiping, and Xiping, and the soil pH mainly ranged from 5.5 to 6.5 (accounted for 84.75% of total surveyed tobacco fields); bacterial wilt had not been found in tobacco-growing fields in Tanghe, Zhengyang, Shangcai, Sheqi, Wuyang and Chenqu, and the soil pH mainly ranged from 6.5 to 7.0 (accounted for 81.25% of total surveyed tobacco fields). There were significant differences in soil pH between the fields with and without bacterial wilt, and soil pH 6.5 could be regarded as the threshold for the occurrence of tobacco bacterial wilt in Henan Province. There was extremely significantly positive linear correlation between soil pH and latitude (y=0.737 5i-17.799, R²=0.386, P<0.01). The geographical boundary of soil pH 6.5 was roughly 33" N, and bacterial wilt was less likely to occur in the north tobacco-growing areas of the boundary. [Conclusion] The study will provide a scientific basis for the prevention and control of tobacco bacterial wilt in Henan. [ABSTRACT FROM AUTHOR]

[Objective] The paper was to explore the influence of near-surface low temperature on cultivation of soft-seed pomegranate, and to provide guidance for planting location of soft-seed pomegranate. [Method] Taking 10 soft-seed pomegranate planting plots under different site conditions as the research objects, the near-surface low temperature of 45-50 cm was dynamically monitored from December 1, 2018 to February 20, 2019, and comparative analysis was made based on the local meteorological data over the same period- [Result] The near-surface low temperature of each temperature monitoring point was lower than the local meteorological data, which were all in the range of low temperature causing freezing injury of pomegranate trees, but the degree of freezing injury was different. The variation of near-surface low temperature was positively correlated with the altitude of terrain, but negatively correlated with the difference of topography and landform. When the local topography and landform were similar, the accumulation time of near-surface low temperature was negatively correlated with the altitude of terrain, while the duration of low temperature directly affected the degree of freezing injury. [Conclusion] The development of soft-seed pomegranate cultivation in Tunisia along Huang Mangling region in Henan Province refers to the local meteorological data. Meantime, it is also necessary' to pay attention to the impact of regional microclimate environment, especially early monitoring of near-surface temperature to select suitable site and natural conditions.

In order to determine the optimal sowing date of ratoon rice in South Henan's rice-growing areas, this paper performs a comparative analysis of rice growth process, seedling quality and yield of first season rice and ratoon rice under different sowing date treatments. The results show that under climatic conditions (2014), by using dry seedling cultivation in a small plastic shed, the growth of seedling sown on February 21 was affected, while the sowing treatments from March 1 to April 11 can breed normal seedlings, and in this period, the maturity period of first season rice was delayed with prolonged sowing date, and ratoon rice yield declined with prolonged sowing date (total production of rice sown on 11 March reaching a peak). Thus, it is considered that the optimal sowing date of ratoon rice in South Henan's rice-growing areas is mid-March. [ABSTRACT FROM AUTHOR]
