摘　　要：以2009年唐山市汉沽农场土地利用数据为基础资料,在ArcGIS软件支持下制作研究区景观类型图,运用景观分析软件PatchAnalyst 4.0提取研究区景观格局指数,通过主成分分析法和聚类分析法,筛选1组能够充分描述景观特征且不存在冗余的景观格局指数,进行研究区土地利用与景观格局分析。结果筛选出4个具有代表性的景观指数,经分析表明研究区景观类型及各斑块面积差异性较大,部分景观斑块形状复杂,景观异质性强,有一定优势景观类型。According to the land use data of Hangu farm in Tangshan in 2009, the landscape type map of this district was made with the support of ArcGIS software. The landscape pattern indexes were extracted by the Patch Analyst 4.0 software. Through principal component analysis and hi- erarchical clustering analysis,a group of landscape indexes which were not only used for describing landscape pattern information but also inde- pendent were selected to analyze the land use status and landscape pattern in the study area. 4 representative indexes were finally selected, and it showed that the landscape pattern differed largely among each patch area, some patches had complex shapes and strong heterogeneity, a few domi- nant landstiaDe types existed in this study area.
