摘要:
川滇农牧交错带位于我国地势第一阶梯向第二阶梯过渡的区域，生态环境复杂而脆弱，是长江上游重要的生态屏障。文中根据1988年和2000年的两期Landsat-TM遥感数据的土地利用解译结果，对研究区的土地利用变化进行了定量分析。研究表明：10多年来，研究区内6种土地利用一级类型的面积和比重变化幅度不大，但是每种土地利用类型的内部组成结构变化显著。同时，土地利用类型之间的转换十分频繁，土地利用空间动态度较高。这种土地利用变化过程，引起了研究区生态系统结构和功能的变化，主要表现在：虽然研究区地广人稀，但是不合理的土地利用方式依然导致了天然林、高覆盖草地、湿地等高生态功能组分的数量减少，出现了森林、草地和湿地生态系统的退化、沙化等现象，生态系统的生产力降低、生物多样性减少等现象，区域整体生态服务功能下降。
Abstract:
Chuandian farming-pastoral zone located in the transition region between the first class to the second stage of hypsography in our country.The eco-environment of research area is complicated and fragile.Based on two-period (1988, 2000) Landsat-TM data and the data of land use of research area, the process of land use change were quantified and analyzed.The result indicates:from 1988 to 2000, the proportion of the six land use type was changing lightly, but the inner structure of each kind of land use changed obviously.At the same time, the land use type transform frequently.The land use change process has lead directly to the structure and function of ecosystem changing.Due to the unreasonable land utilization way, high ecological function, such as the forest, high coverage grassland, wetland etc.decreased severely, the forest ecosystem, grassland ecosystem, and the wetland ecosystem has been deteriorated seriously characterized by the severe desertification of grassland, decline of ecosystem bio-productivity, decrease of biodiversity and so on.The regional ecosystem service was declined.
