基于GIS的诸暨市公园绿地可达性研究

利用网络分析法对诸暨市中心城区内公园绿地的可达性进行了研究,借助洛伦兹曲线来表示建筑物的集散程度并与不同出行方式下的公园绿地可达性差异进行了比较.结果表明:①步行方式下,0～5 m in、5～15 min、15～30 min、30～60 min的可达面积比分别为0.23％、1.21％、4.49％、9.74％.车行方式下...

Accessibility of Urban Park Green Space in Zhuji City Based on GIS

This study focused on the accessibility of urban park green space in the central areas of Zhuji City by utilizing network analysis and the Lorenz Curve is used to express the distribution degree of buildings compared to accessibility differences of park green space under different travel modes.The results show that:①In the walking mode,the available area ratios of 0~5 min,5~15 min,15~30 min and 30~60 min are 0.23%,1.21%,4.49%and 9.74%.In the driving mode,the available area ratios of 0~5 min,5~15 min,15~30 min and 30~60 min are 6.06%,20.43%,33.70%and 39.81%.②The buildings in Jiyang Street are the most centralized.The quantity of parks is large,and the accessibility is high.Taozhu Street is low,and Huandong Street is the lowest.The above research results can provide scientific basis for the planning and construction of urban park green space in Zhuji City.
