我国国家生态旅游示范区空间分布特征研究

A Study on the Spatial Distribution of China National Eco-Tourism Demonstration Area

我国国家生态旅游示范区空间分布特征的研究,有助于为优化其空间布局提供参考。文章利用地理数学方法中的空间分析手段和GIS软件提供的空间分析工具,采用最邻近指数、地理集中指数、基尼系数、不平衡指数和核密度,对我国112处国家生态旅游示范区的空间分布特征进行研究。研究结果表明：国家生态旅游示范区的最邻近点指数为0.83,空间分布类型属于凝聚型;省际分布较为集中,半数分布在11个省级行政区内;在七大地理分区的基尼系数为0.96,呈集中分布的态势,区域分布均衡性很低;分布的高密度区域为长三角地区和京津冀地区。建议改革和完善我国国家生态旅游示范区的评选机制,完善评选标准,加强西部、北部地区生态旅游资源的开发。

The study of the spatial distribution characteristics of China national eco-tourism demonstration area will help to provide reference for optimizing its spatial layout. In this paper, the spatial distribution of 112 national eco-tourism demonstration areas in China is analyzed by means of spatial analysis tools and GIS software. The spatial distribution of 112 national eco-tourism demonstration zones in China is analyzed by the nearest neighbor index, geographical concentration index, Gini coefficient, imbalance index and kernel density Characteristics of the study. The results show that the nearest neighbor index is 0.83 in the national eco-tourism demonstration area, the spatial distribution type is condensed, the inter- provincial distribution is concentrated and the half is distributed in the 11 provincial administrative regions. The Gini coefficient of the seven geographical divisions is 0.96, The distribution of the distribution trend is very low, the distribution of high density areas are in the Yangtze River Delta region and the Beijing-Tianjin-Hebei region. It is suggested to reform and improve the selection mechanism of national eco-tourism demonstration area, improve the selection criteria and strengthen the development of ecotourism resources in western and northern regions.
