摘要
为了解2003年北京城市公园绿地景观格局的构成和特征,在地理信息系统的支持下,选取了景观破碎度、最近邻点指数、平均斑块分维指数与格网分析等方法,通过Patch Analyst软件对北京城八区内的公园进行了分析。其结果表明,城八区内的公园总面积较大,达到了4 380 hm2,最近邻点指数R为1.97,斑块总体趋于均匀分布,整体景观破碎度为2.65,东城区斑块的边界形状较为复杂。值得注意的是,北京西南区域公园数量和面积都较少,应适当加强其区域公园建设。
In order to learn the constitutes and characters of park landscape patten in Beijing in 2003,assisted in Geography Information System,selecting the indices about the Landscape Fragmentation Index,the Spatial Neighboring Index of Minimum Distance,Mean Patch Fractal Dimension Index et al.,Gridding method,the park landscape patterm was analyzed in eight city-zone of Beijing through software of Patch Analyst.The results showed that the total area was 4380 hm2,the Spatial Neighboring Index of Minimum Distance was 1.97,the whole landscape fragmentation index was 2.65,and the distribution of urban park patches regular in the city.The borderline shape was more complex in Dongcheng District.It is worth to note that the area and the number of urban parks in southwest region were less,the park number should be increased in southwest region in future.
