摘　　要：为了解2000年至2005年间北京城市公园的建设发展及所带来的景观格局变化特征,选取了景观破碎度、最近邻点指数和平均斑块分维指数等方法,通过PatchAnalyst软件分别对2000年与2005年北京城八区内的公园进行了分析。其结果表明,2000年公园总面积约为41.28km2,2005年约为47.39km2,在2000-2005年的时间内,公园总面积增长了近608hm2,相对来说,中心城区所含公园面积的比例较高,值得注意的是,北京西南区域公园数量和面积都较少,应适当加强其区域的公园建设。另外,整体破碎度呈增加的趋势,表明新近建设的公园斑块规模面积较小;斑块形状也偏离正方形较大。In order to learn the differentiation characters of landscape pattern change on park in Beijing from 2000 to 2005, supported by the software of Patch Analyst, the landscape pattern indices on park were calculated and analyzed in eight city-zone of Beijing, which include the Landscape Fragmentation Index, the Spatial Neighboring Index of Minimum Distance, Mean Patch Fractal Dimension Index,et al.. The result showed that the total park area was 41.28 and 47.39 square kilometer in 2000 and 2005 respectively, the total park area has increased 608 hectare from 2000 to 2005, comparatively, the center urban zone has bigger proportion of park area than other zone, it should be pay attention to that the park number and area are less in southwest region, the construction of park should be enhance in southwest region in future. And the degree of total landscape fragmentation index was incremental trend from 2000 to 2005, which indicated that the area of recent built park was less in 2005 than 2000, and patch shape also was more departure than square.
