以居住区绿地结构分析和生态效能评价为切入点,借助Fragstats、CITY green等软件分析不同居住区绿地结构与生态效能的特点与差异及绿地结构与生态效能的相关性,为居住区绿地布局提供依据。结果表明:居住区绿地生态效能同绿化覆盖率、三层盖度和、最大斑块面积指数、乔灌草绿地比例、绿地斑块连接度、平均绿地斑块面积呈现正相关性;与景观破碎化程度、绿地斑块平均最近距离呈负相关;并且,良好的树种构成与种植结构有助于提高绿地生态效能。
Taking the analysis of the green space structure and the evaluation of ecological efficiency as the starting point, this paper analyzes the characteristics and differences of green space structure and ecological efficiency and the relativity between the green space structure and ecological efficiency in different residential areas by means of software such as Fragstats and CITY green, in accordance with. The results showed that the ecological efficiency of green space in residential area was positively correlated with the coverage of greening, the coverage of three layers, the maximum patch area index, the proportion of green area, the connectivity of green area and the average area of green patches. The average nearest distance of green patches was negatively correlated, and good tree species composition and planting structure could help to improve the ecological efficiency of green space.
