基于GIS的曲阜市景观格局分析

Analysis on Landscape Pattern in Qufu City Based on GIS

以1987年和2002年TM遥感影像为数据源，在ENVI4．0平台下提取曲阜市1987～2002年景观格局动态变化信息，利用FRAG—STA-S3．3软件提取研究区的斑块指数、形状指数等景观格局指标，并进行分析。结果如下：研究区建设用地、林地面积增加，农用地、水域面积减少；斑块数量、密度增加，形状指数降低。这表明研究区景观格局的变化受人类活动的影响较大，应加大对土地资源的保护并进行合理规划。走可持续发展之路。

With remote sensing TM image of 1987 and 2002 as the data source, extracting landscape pattern of dynamic change information of 1987 and 2002 in Qufu City under ENVI4.0 platform, and use FRACSTATS3.3 to extract the area＇ s plaque index, shape index and so on. The results are as follows ： the area of building land and forest land are increasing; the area of agriculture land and waters are decreasing; the number and the density of plague are increasing, the shape index is decreasing. This shows that the change of landscape pattern is more influenced by the human factors. We should increase the protection of land resources to maintain a sustainable development.
