- 摘要:
- 绿地空间结构极大影响绿地功能，而传统的城市绿地评价过多注重绿地数量，忽视了其空间分布。运用景观生态学理论和GIS、RS技术，以广州市区为研究对象，选取绿地覆盖率、斑块面积等11项指标，通过主成分分析对6个行政区绿地进行比较评价，将评价指标综合为绿地空间格局、绿地形状和绿化覆盖率3个方面。结果表明：越秀区由于绿地分布结构合理，覆盖率较高，综合状况最佳，其次为荔湾区，白云区综合评价最差。评价方法从绿地空间结构的角度完善了传统城市绿地评估体系，为城市绿地规划管理与生态建设提供科学依据。
- Abstract:
- Spatial structures of urban green spaces have great impacts on their functions,but the traditional evaluation took too much emphasis on the number of green spaces,ignoring their spatial distribution.Using landscape ecology theory,GIS and RS technology,11 indexes such as the green coverage,patch area index and so on were selected to evaluate green spaces in Guangzhou.Principal component analysis was conducted and 11 indexes were grouped into three types, the first was landscape pattern index,the second was shape index and the third was the green coverage index.The comprehensive evaluation results showed that Yuexiu district was the best because of the reasonable structure and higher green coverage.Liwan district was better and Baiyun district was the worst.This evaluation method for green spaces system improved the traditional one from the perspective of the structure of green space,and provided a scientific basis for the planning and ecological construction of urban green spaces.
