基于GIS的三门峡市公园可达性分析

基于GIS技术，以三门峡市中心城区城市公园为例，利用网络分析法定量评价步行、非机动车、机动车3种交通方式下的公园可达性，并结合可达面积与人口分析比较研究区、各行政区、各行政街道间的差异。结果表明，研究区内公园分布不均，湖滨区公园多、陕州区公园少；研究区公园绿地非机动车和机动车方式下的可达性较好；步行方式下的可达性较差，只有不到36.11%居民可步行30 min内到达相近公园；湖滨区公园绿地可达性要好于陕州区；前进街道、涧河街道、湖滨街道公园的可达性最佳，会兴街道、张湾乡公园的可达性最差。

Accessibility Analysis of Sanmenxia Park Based on GIS

Based on GIS platform, this paper selected the urban park in the central area of Sanmenxia to quantitatively evaluate the park accessibility under three modes of transportation walking, non-motor vehicle and motor vehicle by using network analysis method, and compare the differences among the study area, administrative districts and administrative streets in combination with accessible area and population analysis. The results showed that the parks in the study area were unevenly distributed, with more parks in Hubin District and less parks in Shanzhou district; the accessibility of non-motor vehicles and motor vehicles in the park green space was good; walking accessibility was poor, and less than 36.11% of residents could walk for 30 minutes to reach the nearby park; the accessibility of park green space in Hubin District was better than that in Shanzhou District; Qianjin Street, Jianhe Street and Hubin Street had the best accessibility, while Huixing Street and Zhangwanxiang Park had the worst accessibility.
