Construction and case verification of rural environmental value-added evaluation system.

How to solve the contradiction between development needs and environmental protection has become the difficulty and focus of rural grass-roots government governance. In this paper, from the two dimensions of information interaction and energy flow, based on the calculation of environmental value-added, a new rural environment environmental value-added model is established, and the reliability of the model is verified by taking the data of Pingding County in Shanxi Province as an example. The results show that: (1) the accuracy of the information flow environmental value-added model is as high as 95.96%, and the model can be applied to the outdoor environment comfort prediction; (2) the comprehensive index of the relative value-added of the ecological environment is reduced from 0.61 to 0.31, and the value-added situation of the ecological environment is negative in the evaluation period, and the development is unbalanced and unsustainable. The trend of continuous development is in line with the actual local development. By measuring the relationship between the gain effect and the cost input of the ecosystem, the model comprehensively analyzes the potential of land and space development and protection in the future, and provides basic support for improving the strategy of main functional areas, drawing up land spatial planning, scientifically delimiting ecological protection red line, permanent basic farmland and urban development boundary, and exercising unified land space use control and ecological protection and restoration, try to open up a new situation of environment and development [ABSTRACT FROM AUTHOR]
