南太行自然保护地空间分布格局及交叉重叠关系研究

以南太行地区5种类型99处国家级和省级自然保护地为研究对象，运用最邻近点指数、地理集中指数和核密度分析法并借助GIS的空间分析功能，对南太行自然保护地的空间分布特征以及交叉重叠情况进行定性和定量分析。结果表明，南太行自然保护地森林公园的数量最多，自然保护区面积最大，长治市内的保护地分布数量最多，整体呈集聚的空间分布类型；其保护地按照密度值可分为3档，大多为点状分布，高密度区主要呈带状和团块状分布在南太行东部地带及部分南部地区；99处保护地中存在27处交叉重叠，风景名胜区交地质公园是最多的重叠类型。

Spatial Distribution Pattern and Cross-Overlapping Relationship of Natural Protected Areas in South Taihang Mountains

This paper studied the 5 types of 99 national and provincial natural protected areas in south Taihang Mountains, used the methods of nearest neighbor index, geographic concentration index, kernel density analysis, and the spatial analysis function of GIS to analyze the natural protected areas of south Taihang Mountains. Qualitative and quantitative analysis of the spatial distribution characteristics and cross-overlapping situation of natural protected areas were carried out. The results showed that the number of forest parks was the highest, the area of nature reserves was the largest, and the distribution number of protected areas in Changzhi City was the highest, and the overall spatial distribution of protected areas in south Taihang Mountains showed agglomeration; the protected areas could be divided into three grades according to the density value, most of which were distributed in a dotted pattern, and the high-density areas were mainly distributed in bands and clusters in the eastern part of south Taihang Mountains and some southern areas; 27 of the 99 protected areas overlapped, and the scenic spots and geoparks were the most overlapping types.
