实证研究大城市区域性公园服务范围——以上海市杨浦公园为例

An Empirical Study on the Serving Area of Regional Park in Megapolis——Case Study of Yangpu Park in Shanghai

针对城市公园系统实际服务范围的界定这一核心问题,以上海市杨浦公园为研究对象,分别运用数据推算法与实证定点法2种方式检验经典理论与现有规范分析下的大城市区域性公园服务范围。结果显示,调查案例中的公园实际服务范围与理论分析的结果存在较大差异,其中又存在由于年龄段差异造成的不同特征,其中,老年游客组与中青年游客组由于游园目的的不同造成其服务特征的变化;在服务范围的空间分布上,大城市区域性公园的核心圈层半径在1000m左右,整体呈不规则多边形,但依然呈现随距离增加而服务效益减小的圈层式分布规律。

To figure out the question of the true serving radium of city parks, two methods are applied to verify the result of regional park serving area calculated by classic theory and criterion. It can be seen that there is obvious difference between the empirical study and the classic analysis. Firstly, in the tourists, the characteristic of the older-age group is evidently different from the young and middle-age group. Secondly, the real serving area of regional park is close to a shape of irregular polygon. Finally, the core serving radius is approximately 1 000 meters, and there is still a regular pattern of ring course from the wholly vision.
