基于网络分析法的公园绿地可达性研究

A study on the accessibility of urban parks based on network analysis method

文章以株洲市中心城区为例,运用了网络分析法探究路网等微观因子对可达性的影响程度,并对可达性进行优化,从而提高中心城区公园绿地可达性水平,促进公园绿地配置合理。研究表明,城市公园绿地的可达性程度依赖路网的完善程度;研究区范围内分布不均衡,主要集中在研究区中西部地区,东侧缺少公园布置;研究区内公园的可达性一般,步行最差,机动车最好,在30 min时才能全部覆盖。

Taking Zhuzhou city center as an example,this paper explores the influence degree of road network and other micro factors on accessibility by using network analysis method,and optimizes accessibility to enhance the accessibility level of urban parks in the central area,promoting a more reasonable allocation of green spaces.The research indicates that the accessibility of urban parks is highly dependent on the completeness of the road network.In the study area,the distribution of parks is uneven,mainly concentrated in the central-western region,with a lack of parks on the eastern side.Generally,the accessibility of parks in the study area is moderate,with walking being the least convenient mode of transportation and motor vehicles being the most convenient,covering all areas only after 30 minutes.
