风景名胜区土地经济密度是衡量旅游用地效益的关键指标.为掌握中国风景名胜区土地利用经济状况、类型和空间差异特征,本文以国家级风景名胜区为研究对象,应用土地经济密度指数、变差异系数和Arcgis空间分析法对中国2003年~ 2009年26个省(市、区)国家级风景名胜区土地经济密度及其差异特征进行分析.结果表明:(1)从全国层面来看,我国国家级风景名胜区土地经济密度总体上呈现逐年上升的趋势,其中陵寝类、壁面石窟类、历史圣地类等三类风景名胜区土地经济密度相对较大;(2)分省层面来看,我国国家级风景名胜区土地经济密度的区域差异明显,区域时间差异变化上大致呈现“整体上升型”、“有升有降型”和“整体下降型”三种类型;区域差异动态特征显示,26个省(市、区)国家级风景名胜区土地经济密度的区域差异随着时间的变化呈现先缩小后扩大的趋势.
The land economic density of scenic spot is the key index for measuring tourism land economic effects. In order to learn about the current state, and the temporal-Spatial features and type differences of land use economic in scenic spots in China, this paper does an empirical research on these two during 2003 - 2009 by taking the national scenic spots in 26 provinces as research object and by using the index of land economic density, coefficient of variable differences and space analysis method in Arcgis9.2 software. The result shows that: (1) from overall aspect, the land economics of National Scenic Spots in China is increasing year by year and with differentiation between scenic spots; From provincial aspect, there are three types of developing trends as a whole: Overall ascension type, Rising and falling type and Overall falling type; (2) The spatial analysis shows that: differences manifest between different areas;The dynamic characteristics of spatial difference demonstrates that the land economy density of national scenic spots of 26 provinces( municipalities, regions) in China varies with time and it narrows first and then widens in the mass.
