基于GIS的聊城市公园绿地可达性分析
|
摘要
以聊城市城市公园绿地作为研究对象,运用地理信息系统(GIS)网格分析功能,对步行、骑行及机动车出行等不同交通方式下城市公园绿地的空间服务区域范围进行分析.结果表明:研究区域内步行方式下,只有不到1/3面积内的居民能在15 min内步行到达公园,骑行方式下有将近1/4面积内的居民不能在15 min内享受城市公园绿地服务功能,而机动车出行方式下5 min内公园绿地可达性面积仅为35.619%,且主要集中在老城区,开发区和高新区城市公园分布相对不均衡.研究成果可为聊城市合理优化绿地空间结构布局提供理论依据.
In this study,urban park green space of Liaocheng was taken as the research object.With geographic information system(GIS) grid analysis,analyzed the spatial service area of urban park green space under different traffic modes such as walking,cycling and motor vehicle travel.The results show that less than 1/3 area residents can walk to the park and nearly a quarter cycling of area residents cannot enjoy city park green space within 15 min.The green space accessibility area is only 35.619% for people with motor vehicle travel mode within 5 min.The green space accessibility area mainly concentrated in the old town.It is unbalanced distribution for development zone and high-tich zone.The results of this study can provide theoretical basis for liaocheng city to reasonably optimize the spatial structure layout of green space.
