An ecoeconomy benefit evaluation of prohibiting grazing policy ——A case study in Yanchi County

Ecological protective policy have obvious effects on the development and restoration of land desertification process. To understand the effects of the prohibiting grazing policy on desertification restoration, Yanchi County was selected as a case study to conduct an ecoeconomy benefit evaluation of prohibiting grazing policy. The analytical hierarchy process method (AHP) was used to build models. Both natural factors and human factors which importantly related to desertification process had been considered in the index system of the AHP method. The results showed that after the implementation of prohibiting grazing policy, the comprehensive benefit, including the ecological, economic and the social benefit, of desertification restoration was significantly higher than that of continuous grazing situation. The prohibiting grazing policy basically realized the expected effects, however it caused with many problems. How to manage the grassland after prohibiting grazing is worth further studying.
