国家级水利风景区空间格局及其资源供需评价
Spatial Pattern and Resource Supply and Demand Evaluation of National Water Conservancy Scenic Areas
摘要
Abstract
Water conservancy scenic spot is a special scenic spot relying on water shoreline or water conservancy project,which plays an important role in the construction of happy rivers and lakes,realizing the ecological protection of the whole basin and promoting the high-quality development of water conservancy.This paper reveals the spatial pattern of national water conservancy scenic areas at the national scale,and evaluates the regional supply and demand of water conservancy scenic resources by means of the reachability opportunity accumulation algorithm.The results are as follows.Firstly,on the national scale,the distribution of scenic spots shows the spatial characteristics dominated by population pattern,which is densely clustered in the east of ″Hu Line″ and sparsely dispersed in the west.Secondly,the connection network between the scenic spot and the city is multilevel.The characteristics of the network formation with the province as the unit are obvious,and the inter-provincial connectivity is insufficient.Thirdly,on the whole,the supply of water landscape resources and the demand of residents show the characteristics of spatial mismatch.The spatial difference of resource supply and demand ratio is higher in northwest,lower in Beijing-Tianjin-Hebei,South China and Southwest China.The research results can provide a basis for the regulation and allocation of hydraulic landscape resources.关键词
