贵州省国家公园选址及其植物多样性保育研究

贵州省生态资源丰富,建立国家公园有利于集中规范化管理生态资源。为了分析贵州省国家级自然保护地的空间分布特征,筛选出优势景观资源聚集区作为国家公园候选区,该文借助ArcGis空间分析工具对现有的5类113处保护地进行空间分布特征分析,筛选出国家公园试点候选区并对其进行资源评价。结果表明:(1)贵州省国家级自然保护地总体呈凝聚型分布,重叠度高,将保护地聚集区作为景观优势聚集区划定了8个国家公园试点候选区。(2)通过对聚集区主要代表性资源分析和专家评分得出,分值排在前列的聚集区可以考虑作为国家公园试点区进行推荐,分值最高的赤水-习水区可优先选为国家公园试点区。(3)赤水-习水区资源的国家代表性、适宜性、国有性和社会可行性等,满足设立国家公园优先整合交叉重叠保护地的基本原则,其植物多样性保育价值重大。该研究结果为国家公园的选址提供了新的思路,并为以国家公园为主体的自然保护地体系建立以及国家公园植物多样性保育提供了参考依据。

Site selection and plant diversity conservation of national park in Guizhou Province

Guizhou Province is rich in ecological resources, and the establishment of national park is conducive to centralized and standardized management of ecological resources. In order to analyze the spatial distribution characteristics of national nature reserves in Guizhou Province, and to screen out the advantageous landscape resource gathering areas for the selection of national parks, we analyzed the spatial distribution characteristics of 113 protected areas in five categories by ArcGis spatial analysis tool, and screened out the candidate areas of national park pilots and evaluated their resources. The results are as follows:(1)The national nature reserves in Guizhou Province are distributed in a cohesive way with a high degree of overlap, and eight national park pilot candidate areas are delimited by taking the reserve gathering area as the landscape advantage area.(2)Based on the analysis of the main representative resources of the gathering areas and the experts''scores, the concentration areas with higher scores can be recommended as the national park pilot areas, and the highest score in Chishui-Xishui area can be selected as the national park experimental area.(3)The national representativeness, suitability, state-owned and social feasibility of Chishui-Xishui area resources can meet the basic principle of setting up national parks with priority to integrate the overlapping protected areas, and its plant diversity conservation is of great value. The results of this study provide a new idea for choosing location of national parks and a reference for the establishment of national parks based on nature reserve system and the conservation of plant diversity in national parks.
