中文摘要	为定量评价禁牧政策对北方农牧交错区草地沙漠化逆转过程的影响程度,以宁夏盐池县为研究区域,选取对沙漠化正逆发展过程影响较大的自然和人为因素指标,应用系统动力学方法构建模型,模拟研究了目前盐池县所实施的禁牧政策对草地沙漠化逆转过程的影响程度,并进行定量化初步评价。研究结果表明,当禁牧程度达到完全禁牧的30%,沙漠化开始出现逆转,而达到完全禁牧的40%,沙漠化的逆转趋势基本趋于稳定。本研究结论可为盐池县及类似地区禁牧政策的合理实施与改进提供理论依据。
英文摘要	Ecological protective policy has obvious effect on reversion of land desertification process.To understand the effect of prohibiting grazing policy on desertification reversion,Yanchi County was selected as a case study area to conduct a quantitative research on the effect of prohibiting grazing policy in this paper.The system dynamics method was used,and both natural factors and human factors significantly related to desertification process were considered in the evaluation index system.Model was set up to simulate response of the degree of desertification to different prohibit extents such as 0%,10%,20%,30%,40%,50%,:,100%.Results showed that the degree of desertification reduced with the increase of prohibiting extent.When the extent was 30%,the desertification reversion began,and when the extent was 40%,the trend of restoration was steady,and the speeds of restoration were the same when the prohibit extent changed from 40% to 100%.These results could be very useful for the applying of prohibiting grazing policy in Yanchi County and other similar regions.
