鄱阳湖生态经济区A级旅游景区空间结构研究

The Research on the Spatial Structure of A-Grade Tourist Districts in Poyang Lake Eco-Economic Zone

通过ArcGIS和地理集中系数、基尼系数、洛伦兹曲线等数理方法,对鄱阳湖生态经济区A级旅游景区的空间结构进行了探讨和分析,将2004、2007、2010和2012年4个时间段A级景区的数量进行对比,并将新增景区与交通干线、重要水系进行叠置,动态分析A级景区空间结构的演化规律.研究结果表明:鄱阳湖生态经济区A级旅游景区在空间分布类型上属于集群分布,空间结构上呈多核-边缘结构,等级规模上为纺锤型结构,空间上呈现非均衡的分布态势,时间上呈现沿交通干线和主要水系的演变规律.

Based on the spatial analysis of Geographical Information System and the methods of mathematical statistics,such as geography concentrate ratio,Gini ratio,Lorenz curve,this paper takes Poyang Lake Eco-Economic Zone＇s A-grade tourist districts as cases to analyze and discuss.Discuss the number＇s change of the attraction in the year of 2004,2007,2010,2012,and combine new addings with the road of transport and main rivers to expose the dynamic changes in the spatial patterns.The result shows that the distribution of Poyang Lake Eco-Economic Zone＇s A-grade tourist districts is a style of concentrating distribution,while the spatial structure tends to be multicores-peripheral.And it＇s class-scale is a spindle-structure,the spatial and time distribution appear unbalanced concentration and along main roads and rivers.
