Spatial Structure Differences and Optimization of National Tourism Areas above 4A Level in Anhui Province

Taking national tourism areas above 4A level in Anhui Province as the research object,this paper studies the spatial structure types,geographic concentration degree,distribution density and equilibrium degree,as well as benefit difference of tourism areas by using the methods of the nearest point index,geographic concentration index and Gene coefficient,and discusses the influencing factors that restrict the spatial development of tourism areas from regional economic developmental level,tourism traffic and tourism resources. On this basis,it puts forward some strategies for the optimization of spatial structure in Anhui tourism areas such as increasing policy and financial support,deeply developing northern Anhui tourism regions,making full play of the leading role of southern Anhui tourism areas,constructing convenient traffic network,strengthening tourism cooperation and so on.
