摘要
针对城市景点空间分布的公平性问题,以武汉市为例,使用增强的二步移动搜索法(E2SFCA)对武汉市景点的潜在可达性进行了研究。分别选取60 min、180 min作为最大搜索范围,分别得到了E2SFCA可达性效果图。分析结果可知,武汉市景点潜在空间可达性不均衡,整体上表现出中心城区可达性较高边远辖区可达性较低的圈层结构。最大搜索范围为180 min的可达性比60 min的可达性均衡性好,圈层结构更明显。
As for the equity issues of urban scenic spots spatial distribution,taking Wuhan city as example,the enhanced 2-step floating catchment area（E2SFCA）method which is a recent extension of the gravity model is used to analyze potential spatial accessibility. 60 min and 180 min were selected respectively as the catchment size of the E2 SFCA method. Comparative analysis result indicates that the spatial structure of Wuhan＇s scenic spots is unbalanced. The accessibility of city＇s downtown is higher than those of the remote area. Distribution of spots regarding the accessibility shows a concentric pattern. The accessibility of 180 min is better than 60 min,and the circle structure is more obvious.
