| 摘 要： | 基于遥感（RS）和地理信息系统（GIS）技术，以Landsat TM/ETM图像为基本数据源，综合运用景观生态学理论和方法，对我国典型农牧交错生态脆弱区宁夏盐池县1991~2000年生态景观格局动态变化进行了研究。结果表明： 盐池县各景观类型都发生了很大程度的消长变化，景观格局处于快速调整和不稳定发展阶段，但生态景观基质还是草地，景观格局始终呈农牧交错结构。

| Abstract: | Based on the GIS and RS techniques and the Landsat TM/ETM data and applying the principle of Landscape Ecology and the technique of GIS, the authors studied the dynamic change of the landscape pattern from 1991 to 2000 in Yanchi County of Ningxia, one of the typical farming - pasture ecotonal areas in China. It is concluded that the areas of all types of landscapes in Yanchi increased or decreased to some extent, that the landscape pattern was at the unstable stage, with the pasture remaining the eco -landscape matrix, and that the principal landscape pattern was still characterized by the farming -pasture ecotone. |
