基于可达性的山地城市公园绿地服务范围分析及布局优化——以万盛经济技术开发区为例

On Accessibility-Based Analysis of City Park Green Space Service Range and Layout Optimization——A Case Study in Wansheng Economic and Technological Development Zone

通过GIS建立以道路网络为基础的道路矢量数据库和包含公园名称、入口和面积等要素的公园数据库,采取网络分析法分析了万盛经济技术开发区公园绿地的假日游览服务范围和日常游憩服务范围,得出了4种服务盲点类型:真空盲点、车行服务盲点、步行服务盲点和隐形盲点.不同类型的盲点为选址分析提供依据,并结合盲点区的用地性质、人口分布和自然条件等因素优化绿地布局.

The study probes the road vector database based on the GIS road network, and the city park da-tabase including the names, entrances, areas and the other elements of parks. The holiday and the daily service ranges in Wansheng Economic and Technological Development Zone have been worked out through the network analysis. There are 4 types of blind spots of parks, namely empty space blind spots, vehicle transport service blind spots, walking service blind spots and latent blind spots. Different types of blind spots can provide basis for site selection analysis, which could be used together with the land usage, the population distribution and the natural conditions of the blind spots to optimize the layout of green space.
