基于GIS的广州市番禺区土地景观格局破碎化分析

Landscape Fragmentation Analysis of Panyu in Guangzhou Based on GIS

以景观生态学理论为指导,选用各项景观格局破碎化指数,对不同时期的土地利用景观格局破碎化进行分析。结果表明,番禺斑块数量、斑块密度、边界密度与斑块破碎化指数均有不同程度增加,景观整体破碎化程度逐年加深,20世纪90年代中期以后破碎化程度加深趋势相对平稳。

The landscape fragmentation of Panyu in different periods were analyzed choosing some landscape indexes.The patch number,density index,edge density index and patch fragmentation index in Panyu increased to some extent,which meaned that landscape fragmentation degree became higher.The fragmentation degree of all landscape types became higher year by year,and became stable after 1995.
