<正>为了解人为影响下森林景观空间特征的历史变化，应用地理信息系统（ＧＩＳ）技术研究了溧阳地区森林景观空间格局的动态变化特点。通过计算景观生态学研究用的几个空间特征指标，结果表明破碎度、景观形状指数降低，优势度增大。经综合分析，认为研究区域的森林景观早已逾越了在人为影响下趋于破碎化和异质性提高的阶段，目前在人为的影响下趋于均质性。

In order to recognize the influences of which human act to the forest landscape, in the paper, the dynamic of spatial patten of forest landscape in Liyang district was studied by using GIS technology. Some indice used frequently in landscape ecological research such as domiance of landscape were calculated and analysed synthetically. It was concluded that the forest landscape in Liyang district was beyond the stage in which the heterogeneity would increase when influenced by human actions, and in the stage of tending to homogeneity.
