本文在简要介绍地理信息系统（ＧＩＳ）与景观生态学基础理论的基础上，分析了ＧＩＳ在景观生态学，尤其是在景观空间格局分析与景观时空变化分析与模拟方面的应用，指出ＧＩＳ在这两方面应用中应注意到的几个问题，即，时空尺度的选择、景观信息机理的研究、小区域研究、专业模型与通用ＧＩＳ接口问题及点值数据到面数据的外推问题。

In the paper, the author makes a brief introduction to Geographical Information System and basic theories of landscape ecology at first, then makes an analysis on the application of Geographical Information System in studies of landscape ecology, especially in respects of analysis of landscape patterns and landscape change modeling. In the end the author suggests some points worth noticing,(1) proper choice of spatialtemporal scale,(2) studies of landscape information,(3) small area researches, (4) interface problem of landscape models and general GIS, and (5) data extroplation from point to area.
