景观空间格局特征研究是景观生态学研究的核心内容。利用软件ArcGIS 9.2和Fragstats 3.3对香格里拉县各景观类型进行景观指数计算，得出不同空间尺度上各景观指标的数量特征，从粒度上对景观进行不同空间尺度效应的分析，可准确掌握一个地区的景观格局及其随尺度变化的过程，对进一步开展景观生态规划与建设具有十分重要的意义。
The research of the landscape spatial pattern characteristics is the main content of landscape ecology research. The softwares, ArcGIS 9.2 and Fragstats 3.3, are used to calculate various types of landscape index in Shangri-La, and to conclude the quantitative attribute of various types of landscape index in different special scales. And from the granularity a detail analysis of the landscape of different special scale effect is made, so that we can accurately grasp the landscape pattern in one area and the process of its change with scales. It has a great significance for the further development of the landscape’s ecological planning and construction.
