首发时间:2008-09-17
摘要:为了解2005年北京城市公共绿地景观格局的构成和特征,以北京城八区所含的规划市区为研究区域,在地理信息系统的支持下,选取了平均斑块面积、平均斑块形状指数、平均斑块分维指数等,通过Fragstats软件对公共绿地进行了格局分析。其结果表明,公共绿地总面积较大,达到了6431.26公顷;整体景观的平均斑块分维指数值为1.09,反映了城市公共绿地受人为干扰强烈的特性;另外,整体景观的平均斑块最近邻体距离为131.56 m,也反映出公共绿地斑块之间联系较为紧密。

Abstract:In order to learn the constitutes and characters about landscape pattern on the public green space in Beijing on 2005, Taking Beijing planning area of eight city zone as study region, assisted in Geography Information System, select the indices about the Mean Patch Area, the Mean Shape Index, the Mean Patch Fractal Dimension et al., the landscape pattern of the public green space was analyzed through Fragstats software. The result showed that the total area of the public green space was 6431.26 hectare. The average fragmentation index was 1.09 in total, which indicated the characters for human strong interference to the public green space, other, the average Neighboring value of Minimum Distance was 131.56 m in total. which indicated the patches were closely interrelated each other.
