文章摘要：為定量評(píng)價(jià)禁牧政策下鹽池縣草地沙漠化逆轉(zhuǎn)過(guò)程的綜合效益,本研究選取了對(duì)沙漠化正逆發(fā)展過(guò)程影響較大的自然和社會(huì)經(jīng)濟(jì)影響指標(biāo),應(yīng)用層次分析法構(gòu)建模型,模擬研究了目前鹽池縣所實(shí)施的禁牧政策對(duì)草地沙漠化逆轉(zhuǎn)過(guò)程的影響程度,并進(jìn)行定量化的初步評(píng)價(jià)。研究結(jié)果表明,完全禁牧后,鹽池縣草地沙漠化逆轉(zhuǎn)過(guò)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(jì)效益與社會(huì)效益均呈升高趨勢(shì),表明禁牧政策基本實(shí)現(xiàn)了預(yù)期效果,但禁牧政策同時(shí)也帶來(lái)許多問(wèn)題,后禁牧?xí)r代草地應(yīng)如何管理值得進(jìn)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.
