摘要:

基于GIS技术,运用成本距离加权法,从可达性和服务效率两个角度对苏州河滨水空间中心城区段的公园绿地服务状况进行了量化分析和研究。结果表明:(1)公园绿地在苏州河南北沿岸均匀分布,滨水空间东段和中段公园绿地分布较西段多且大,但整体上公园绿地面积占比较小;(2)在仅考虑步行阻力的情况下,78.27%的区域到达最近公园绿地的步行时间不超过30 min,只有11.07%的区域步行到达公园绿地的时间超过60 min,滨水空间的绿地可达性较为合理;(3)在考虑综合阻力的情况下,可达性优良的第Ⅰ、Ⅱ等级区域的服务面积比和服务人口比分别仅为60.84%和54.86%,滨水空间的公园绿地服务效率还有待提高。

Abstract:

Based on GIS technology, we used the cost-distance weighting method to quantitatively analyze and study the service status of park green in the central urban section of Suzhou River waterfront space from two perspectives of accessibility and service efficiency. The results show that(1)the park green are evenly distributed along the north and south of Suzhou River, but overall the area of park green in the research area accounts for a relatively small percentage.(2)78.27% of the areas have a walking time of less than 30 minutes to reach the nearest park green,and only 11.07% of the areas have a walking time of more than 60 minutes to reach the park green, so the accessibility of park green in waterfront space is reasonable.(3)The service area ratio and the service population ratio of the Ⅰ and Ⅱ grade areas with excellent accessibility are only 60.84% and 54.86% respectively, and the service efficiency of park green in waterfront space still needs to be improved.
