常德市旅游地的空间结构研究

On the Study of Spatial Structure of Tourism in Changde

根据内部结构决定功能的原理,以节点的方式把常德市区的旅游地作为旅游吸引作用的聚集体,置于同一规模水平的网络框架中,利用结点的邻接矩阵、可达矩阵及旅游地吸引模型,进行空间分布结构、空间关系研究。结果表明:旅游地空间相互吸引力指数大于0.5的旅游地有河山森林公园、柳叶湖、夹山、桃花源、花岩溪。从区域看,常德市旅游地结构呈现出以常德市区为中心的类同心圆圈层结构,随着圈层半径的扩大,旅游地吸引力逐渐减小。

According to the principle of inner structure deciding its function , the spatial structure and relation are analyzed by the method of adjacency matrix , accessibility matrix and gravity model . The result indicates that the tourism places Yuan, whose spatial attraction index （SAI） is larger than 0.5 are Hefu Mountain, Luye ＂Lake, Jia Mountain, Taohua-Yuan. Huayanxi. From the region part, the structure of tourism places in Changde shows concentric - circle - like characteristic centering on Changde City. The attraction of tourism will gradually decrease with the expansion of radius of the circle.
