摘要

以宁夏盐池县为研究对象，以4期卫星遥感影像为数据源，应用遥感、地理信息系统及景观生态学原理，在获取大量数据的基础上，采用定量的方法深入分析了研究区的景观格局状况。结果显示，在研究时段内盐池县土地景观空间格局发生了显著变化，整体景观的破碎度和多样性指数在不断上升，优势度指数不断降低，均匀度指数持续增加，景观格局朝着农、林，牧多优势度的趋势良性发展。盐池县生态环境状况正在逐步得到改善。

Abstract

By the way of RS

GIS

and the theory of landscape ecology

and on the base of great many data

this paper analysed the status of landscape pattern of Yanchi County.The results indicate that Yanchi's landscape pattern changes significantly during the research phase

the fragmentation and diversity index of entire landscape being on the rise

the dominance index reduced

and the evenness index increased.The pattern shows a varied development tendency of agriculture

forestry and animal husbandry.At the same time

the condition of ecological environment of Yanchi County has been improved step by step.
