摘要
研究目的:筛选一组代表性景观格局指数进行区域土地利用特征描述和土地利用分区。研究方法:景观格局分析软件应用、主成分分析和聚类分析方法。研究结论:仙侬景观多样性指数、景观分离指数、斑块密度、景观形状指数、周长/面积分维数这一组景观格局指数可以很好地表征德州市土地利用特征;基于选定的景观格局指数可以将德州市分为4种类型区。
The purpose of this paper is to select a group of representative landscape pattern indices to describe the regional land use characteristics and conduct land use division. Methods employed include application of landscape pattern analysis software, principal component analysis（PCA）and clustering analysis. The results indicate that the group of indices including Shannon＇s diversity index, landscape splitting index, patch density, landscape shape index and perimeter/area fractal dimension can describe the land use characteristics of Dezhou city comprehensively. The land use in Dezhou city can be divided into 4 types based on the selected landscape pattern indices.
