文章摘要：為定量評價禁牧政策下鹽池縣草地沙漠化逆轉(zhuǎn)過程的綜合效益,本研究選取了對沙漠化正逆發(fā)展過程影響較大的自然和社會經(jīng)濟影響指標,應用層次分析法構(gòu)建模型,模擬研究了目前鹽池縣所實施的禁牧政策對草地沙漠化逆轉(zhuǎn)過程的影響程度,并進行定量化的初步評價。研究結(jié)果表明,完全禁牧后,鹽池縣草地沙漠化逆轉(zhuǎn)過程的綜合效益明顯優(yōu)于自由放牧情景,生態(tài)效益、經(jīng)濟效益與社會效益均呈升高趨勢,表明禁牧政策基本實現(xiàn)了預期效果,但禁牧政策同時也帶來許多問題,后禁牧時代草地應如何管理值得進一步研究。

Abstr：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.
