摘要
为了分析上海市社区绿地空间分布特征并提出优化策略,作者选取了上海不同建设年代的3个典型城市社区:黄浦瑞金社区、闵行莘城社区和松江方松社区,通过对比分析各社区绿地景观斑块的平均分维数、聚集度指数、破碎度指数、蔓延度指数、连接度指数等景观生态学指数,来研究上海城市社区绿地的空间分布特征。研究结果表明:1)瑞金社区、莘城社区和方松社区的破碎化指数分别为0.77、0.45和0.40,瑞金社区的绿地景观破碎化程度最高,莘城社区和方松社区的绿地景观破碎化程度明显低于瑞金社区。2)瑞金社区、莘城社区和方松社区的蔓延度指数分别为76.16、69.02和66.14,反映出方松社区绿地分布较为均匀。3)瑞金社区、莘城社区和方松社区的连接度指数分别为40.07、53.18和70.61,表明方松社区中各类型绿地斑块间的空间联系较为紧密。
Research on the green space pattern of community has practical meaning for analyzing green space distribution and optimizing its structure.In this paper,three typical communities constructed at different times in Shanghai were studied including Huangpu Ruijin community,Minhang Xincheng community and Songjiang Fangsong community.The spatial distribution of green space in the three communities was surveyed and analyzed through landscape indexes including landscape patch fractal dimension,aggregation index,fragmentation index,contagion index,and connectivity index.The results showed that 1)the fragmentation indexes of Ruijin,Xincheng and Fangsong were 0.77,0.45 and 0.40,respectively.The degree of green landscape fragmentation of Xincheng or Fangsong was significantly lower than that of the Ruijin;2)the contagion indexes of Ruijin,Xincheng and Fangsong communities were76.16,69.02 and 66.14,respectively,reflecting the more uniform distribution of green space of the Fangsong community;3)the connectivity indexes of the three communities were 70.61,53.18 and 40.07,respectively,showing that the green space of Fangsong community is closely connected.
