【 摘 要 】

In order to solve the problem that the current rural environment value-added benefits are difficult to estimate, based on the emergy theory, this paper built a rural environmental value-added evaluation system with resources, development, space and environmental protection as the main elements, including 18 sub-indicators. This study also quantitatively evaluated the value-added situation of ecological environment in Queshan Village, Shanxi Province, from 2010 to 2015, and put forward development strategies. It is found that from 2010 to 2015, the resource factor decreased from 0.02 to 0.00, the development factor decreased from 0.16 to 0.06, the space factor increased by 0.19 from 0.07, the environmental protection factor decreased from 0.21 to 0.05, and the composite index decreased from 0.61 to 0.31. The results show that the ecological environment of Queshan Village was negative in the evaluation period, and the development showed an imbalance law and an unsustainable development trend. This method constructs a quantitative analysis system for rural environmental value-added evaluation, and has certain theoretical and practical value in rural planning guidance and evaluation.
