基于GIS和RS的徐州市景观格局演变研究

Study on the Landscape Spatial Pattern Evolution of Xuzhou Based on GIS and RS

基于19791、9942、003年遥感影像,在GIS和RS的支持下,解译提取徐州市20多年来的景观类型的空间信息,选取分维数、景观优势度指数、均匀度指数、多样性指数、平均斑块伸长指数、破碎度和分离度指数,对徐州市景观空间格局的时空动态演变进行了分析。

Based on RS images from three period（ 1979, 1994 and 2003 ） and with the support of GIS and RS, the spatial information of landscape in Xuzhou city during 1979 - 2003 was extracted and with the models of mean patch fractal dimension,dominance,evenness,diversity,mean patch elongation index,fragmentation and isolation,the dynamic spatio-temporal changes of landscape patterns of Xuzhou was analyzed.
