RESEARCH ON TOURISM SPATIAL STRUCTURE OF ANHUI PROVINCE——BASED ON TOURISM CENTRALITY DEGREES AND TOURISM ECONOMIC CONTACT
用因子分析和引力模型计算安徽各市旅游中心度，发现合肥和黄山是双核心，皖北强于皖南，并划分出四大旅游经济圈。
On the basis of related theories of tourism economy's space and structure,and statistics in statistical yearbooks and social statistical bulletins,this paper uses the methods of factor analysis and the gravity model to calculate the tourism centrality of each municipality in Anhui province.According to the result,Hefei and Huangshan are tourism central cities in Anhui Province.Anhui province is developing in a dual-core linkage development mode and there exists an apparent situation that the northern Anhui is strong while the south is relatively weak.Influenced by the geographical and traffic conditions,urban tourism centrality doesn't have the necessary correlation with tourism economy's correlation.Anhui province has four circles of tourism economy:big Hefei tourism economic circle;Wanjiang urban tourism economic belt;South Anhui international tourism economic circle and big north Anhui tourism economic circle.
