中国国家地质公园空间分布及其演化研究

Study on the Spatial Distribution and Its Evolution of National Geoparks in China

2001年4月至2013年12月,国土资源部正式批准授牌了七批共240处国家地质公园。随着国家地质公园数量的增长,其在空间上呈现出一定的分布结构和演化规律。通过GIS空间分析发现:中国国家地质公园在空间上呈现显著凝聚分布;空间分布不均,具有空间集群分布的特征;分布的高密度地区为1个带状区域和4个块状区域。通过对不同阶段国家地质公园空间分布的分析,发现中国国家地质公园分布重心向北迁移、与区域中心城市的关系日趋紧密。地质构造条件、地质公园的旅游化以及拟建地政府部门认知水平是影响国家地质公园空间分布演化的重要因素。

Since Ministry of Land and Resources of the PRC recognized the first national geoparks in 2001, China have two hundred and forty national geoparks by the end of 2013.The growth in the number of national geop-arks has shown a certain spatial pattern and evolution of the distribution .GIS spatial analysis shows that the distri-bution of 240 national geoparks is a type of agglomeration and the distribution of national geoparks in 31 provinces is asymmetric.According to the Lorenz Curve , more than half of national geoparks concentrate in 10 provinces. The distribution of high density area are one zonal region and four plane regions .The analysis on the change of the spatial distribution of national geoparks in different period shows that the mean center of national geoparks moved to the north and the spatial relationship between national geoparks and regional central city are becoming more and more closely .Geological conditions , tourism development of national geoparks and the cognitive level of the local government and the leadership are the main factors which affect the evolution of spatial distribution of national geop -arks.
