The implementation of the "Belt and Road" strategy not only promotes the coordinated development of China's regional economy but also generates a large amount of greenhouse gas emissions. The research and policy recommendations on agricultural carbon emissions are of great significance for China toward engendering sustainable agricultural development and appreciably contributing to the alleviation of global climate change. In this paper, agricultural carbon emissions in the Belt and Road region of China from 2003-2018 are calculated, and its spatial-temporal characteristics are analyzed. Then, we modified the logarithmic mean Divisia index model from the original four factors to six to analyze the drivers of agricultural carbon emissions. The research results obtained are as follows: (1) Total carbon emission reached a peak of 26.6326 million tons in 2016, representing a 54.53% increase from the 17.2342 million tons in 2003. Moreover, it indicated a downward trend in 2017 and dropped by approximately 4% to 25.5685 million tons in 2018. (2) Spatially, agricultural carbon emission varies greatly, with the highest value recorded in Heilongjiang and the lowest in Tibet, thereby exhibiting the characteristics of "northwest>northeast>southwest>southeast." (3) Overall, the economic factor was the most important driving factor, whereas the subsidy factor was the strongest inhibiting factor for the growth of agricultural carbon emissions. Notably, the foreign trade factor had both promoting and inhibiting effects on it. [ABSTRACT FROM AUTHOR]

Tibet Autonomous Region is located in the southwest of China. As a special area with high altitude, low temperature, abundant and diverse resources, the development of agricultural modernization has itself development attribute and feature. Agricultural development area of Tibet mainly concentrates in the "one river and two streams" basin. In this paper, combining the development of modern agriculture on the plateau, the connotation and characteristics of the development of plateau modern agriculture are illustrated from the angle of environment economics. Based on the observation method, linking theory with practice and combining literature research method, descriptive study is conducted, and the specific problems in the development of plateau modern agriculture in the agricultural basin are found. For example, the development of agriculture in Tibet has low utilization rate of resources and unbalanced distribution, agricultural mechanization shows gradient development, productivity and agricultural extension are backward, efforts to promote innovation and science knowledge are not enough, agricultural pollution expands, and the awareness of environmental protection is low. In view of the above problems, we put forward some countermeasures and suggestions: developing local advantage characteristic agriculture, developing cooperative economic organization, establishing the training promotion mode of theory combining with practice, establishing agricultural industry system of sightseeing tourism ecology. The research could provide theoretical suggestions for the future development of plateau modern agriculture. [ABSTRACT FROM AUTHOR]
