特大城市核心区绿地格局量化比较研究r——以北京、伦敦、巴黎、纽约为例

摘要

城市绿地对于解决特大城市可持续发展问题有重要意义.城市绿地格局的特征受到历史发展进程、自然格局与城市重大事件等影响,同时,绿地格局也会直接影响特大城市的区域结构、空间布局、生态环境和城市风貌.该文选取四座典型的特大城市——北京、伦敦、巴黎、纽约作为研究对象,比较四座城市核心区绿地格局的演变历史,以及绿地面积、形态、密度、布局模式、规模尺度等绿地格局相关要素,并进行量化对比研究.最终通过比较分析得到四座城市核心区绿地格局的典型特征与影响因素,为未来特大城市绿地的发展提供依据.%Urban green space was very important to urban sustainable development. Green pattern was formed by urban history, natural pattern and important events. Meanwhile green pattern had directly affected megalopolis structure, spatial distribution, ecological environment and urban style. Selecting four typical megalopolis: Beijing, London, Paris and New York as the objects of study, we compared the green space evolution history of four cities' central areas, and we also made quantitative comparison on green area, shape and density, layout pattern and scale and so on. Finally, we obtained typical features and influencing factors of four cities' central areas green pattern, so as to provide basis for development of megalopolis green pattern.
