    绿斑密度:高密度城市绿地规划布局适用指标研究——以澳门半岛为例

    摘要:高密度城市因人口与建筑超量集聚,常导致绿地不足、自然景观稀缺、环境质量恶化等问题。选取澳门半岛为研究对象,提出适用于高密度城市绿地系统规划布局的空间绿量评价指标——“绿斑密度”(GPD),探讨它与绿地布局影响因子之间的相关性。研究内容结合2010、2015年所做的澳门半岛城市绿地普查工作,阐述了绿斑密度与城市绿地边界周长、街区人口密度、微绿地空间生态效益等影响城市绿地布局与使用效率关联因子之间的关系。通过SPSS分析得出以下结论:在绿地率相当的情况下,GPD值与绿斑布局的分散程度及居民到达使用的方便程度呈正相关联系;街区人口密度与GPD呈正相关联系,与绿斑平均面积呈反相关联系;随着城市街区人口密度增加,绿地斑块趋向以面积微小、密度较高的模式发展。

    Abstract:There are many problems in high-density cities such as the shortage of landscape, and the deterioration of the quality of human habitat because of the overloaded people and buildings. This paper selects the green space in Macau peninsula as an example and proposes the index of "Green Patch Density (GPD)" and the relevance between GPD and patterns of green space. Using the statistics of Macau (2010, 2015), this paper analyzes the relevance of GPD and green space service boundary perimeter, GPD and district population density, GPD and micro green space ecological effect. The main conclusions are as follows: GPD is positively correlated with the density of green patch and the convenience for residents; the density of population is positively correlated with the new green patch density, and the density of population is negatively correlated with the average area of green patch.
