| 摘 要： | 公园绿地的可达性是衡量其空间布局合理性的重要指标,以出行距离来度量公园绿地的可达性是一种较为便捷和有效的方法.以乐清市城区为例,根据公园绿地的规模,设置相应的服务半径,借助ArcGIS网络分析工具,基于出行距离来评价公园绿地的可达性.与缓冲区分析和按统一服务半径(500m)进行分析对比,本方法更接近实际.

| Abstract: | Accessibility is the important criteria for evaluation of public park＇s spatial distribution. Using travel distance to calculate public park＇s accessibility is always easy and effective. Taking Yueqing City as an example, different service radius was set for each public park according to its size, and its accessibility was evaluated based on travel distance by utilizing network analysis tools of ArcGIS. Compared with the classical method-buffer analysis and the method using the unitary service radius regardless of public park＇s size, the proposed method was more accurate to analysis public parks＇ accessibility. |
