Abstract:

Understanding the characteristics of spatial 〖JP2〗differentiation in the basin is a key to make a scientific〖JP〗 decision and promote sustainable basin economic development.Based on 10 economic indices in the main countries and cities which Jialing River flows through，this paper calculates the general score of basin economic level by using SPSS，and analyzes the spatial differences of basin economic level by means of  spatial analysis provided by Geoda.The analysis shows that there are great  differences in the economic level，and the geographical concentration exists in the basin economic.A “pointaxis” spatial structure has been basically formed，and there are two economic hot spot，that is “MianyangChongqing” dualnuclei zone，as well as a economic blind zone which is a border district at the junction of Shanxi，Gansu and Sichuan province.Based on the status of the spatial differentiation of Jialing River basin,this article gives the main reasons for the  differentiation and puts forward several proposals on hot spot and blind zone,in order to prevent the acceleration of the “polarization” effect,and to provide evidence for the harmonious development of basin economic
