中文摘要	通过野外调查和对2000年TM影像的解译,分析了研究区土地沙漠化的分布格局与发展态势,以及土地沙漠化造成的负面影响.从气候因子的时空分布与变化和人地关系两大方面,探讨了研究区土地沙漠化发生、发展的原因.结果表明,沙漠化土地在空间分布上,与春季风蚀气候因子分布范围不一致;沙漠化在发展的速率上,与三大气候因子的动态变化不一致.结论指出:近50年来,气候因子的时空变化不是研究区土地沙漠化的主要原因;人畜压力与环境容量严重失衡,研究区人地关系的管理上屡有失误,落后的生产、生活方式转变缓慢,是造成研究区土地沙漠化的本质原因.
英文摘要	Through making field investigation and using the results of 2000 TM images classified) the distribution patterns and development trend of land sandy desertification as well as its causing negative affection were analyzed in this paper. In the view of the spatial distribution and temporal variation of climatic factors and the relation be-tween mankind and earth, the driven factors of occurrence and development of land sandy desertification was ex-plored. The results showed that the spatial distribution of land desertification was different with the scope of the wind erosion climatic factor in spring; that the development rate of land sandy desertification disagreed with the variation of three main climatic factors. The final conclusion drew is that the main reason of land sandy desertifica-tion in study area in the last 50 years isn’t the temporal and spatial variation of climatic factors. The real reasons are the serious unbalance between the pressure coming from man and livestock and the environmental capacity; the worse management on the relation between human and land; the unenlightened and extensive production and living styles.
