中国自然保护区与国家地质公园空间分布差异

Spatial distribution difference of national nature reserves and national geoparks in China

基于自然保护区和国家地质公园两种保护形式的空间信息,利用Arcgis 9.3分析软件、地理集中指数和综合密度指数量化分析自然保护区和国家地质公园空间差异。通过反距离加权插值法求出自然保护区和国家地质公园与全国主要城市距离远近,讨论两种保护区形式对城市依赖性以及与生态旅游发展关系。结果表明,自然保护区和国家地质公园在空间分布上呈现"东密西疏"格局,两种保护形式都相对集中在中国中东部人口密集地区,西部较少。国家地质公园分布与城市有一定规律性,保护独特的地质遗迹,减轻旅游对自然保护区压力。

Based on the spatial information of two protection forms, by Arcgis 9.3 analysis software, geographic concentration index and the integrated density index and quantitative analysis were used to analyze the spatial difference of national geopark and Nature Reserves. By inverse distance weighted interpolation method nature reserves, national geoparks and their distance relationship with major cities were determined, the dependence of two forms on the cities and their effects were also discussed, combined with the ecotourism development model in the two kinds of protection forms. The results showed that nature reserves and national geoparks presented the pattern of ＂intense in East and sparse in West＂. Two kinds of forms were relatively concentrated in densely populated areas in the eastem China. The distribution of national geopark had certain relevance with the cities, and also had important impacts on the urbanization construction. Not only for protecting the unique geological relics, but also improving the social and economic benefits and helping alleviate the pressure of tourism on nature reserves.
