【摘要】:保护地是我国自然遗产与文化遗产的重要载体。基于保护地类型的多样性和区域地理条件与历史脉络的差异性,借助Arc GIS、SPSS软件分析,以长江中下游地区6省1市为研究区域,以自然保护区、风景名胜区、森林公园、地质公园、水利风景区、湿地公园、文物保护单位、历史文化名城及历史文化名镇名村9类国家级保护地形式为研究对象,引入最邻近点指数、地理集中指数及Kernel核密度指数分析长江中下游保护地空间分布特征,并运用主成分分析法分析影响自然与人文保护地分布的主要因素。结果表明,保护地总体趋于集聚分布,但自然保护区、森林公园、地质公园和历史文化名城的最邻近点指数R1,趋于均匀分布,其他类型的保护地均呈集聚分布。省域保护地地理集中指数江苏最高,江西最低;各类型保护地地理集中指数相差不大,分布较为均衡。自然保护地分布形成环太湖都市圈、南京都市圈、武汉都市圈和长沙都市圈4个高密度地区;人文保护地高密度地区集中在浙江、安徽和江苏3省。自然保护地分布受资源禀赋影响最大,而人文保护地与城市发展状况关系紧密。
[Abstract]:Protected land is an important carrier of natural heritage and cultural heritage in China. Based on the diversity of the types of protected areas and the differences between regional geographical conditions and historical context, and with the aid of Arc GIS-SPSS software, this paper takes 6 provinces and 1 city in the middle and lower reaches of the Yangtze River as the research area, and takes the nature reserves, scenic spots and forest parks as the research areas. Geological parks, water conservancy scenic spots, wetland parks, cultural relic conservation units, historical and cultural cities and famous towns and villages are 9 types of state-level protected sites, and the nearest point index is introduced. The geographical concentration index and Kernel nuclear density index are used to analyze the spatial distribution characteristics of the protected land in the middle and lower reaches of the Yangtze River, and the principal component analysis method is used to analyze the main factors affecting the distribution of natural and human protected land. The results showed that the protected land tended to gather and distribute, but the nearest point index R1 of nature reserve, forest park, geopark and historical and cultural city tended to distribute evenly, while the other types of protected land were clustered. The geographical concentration index of provincial protected land is the highest in Jiangsu province and the lowest in Jiangxi province, and the geographical concentration index of each type of protected land has little difference, and the distribution is more balanced. There are four high density areas around Taihu Metropolitan Circle, Nanjing Metropolitan Circle, Wuhan Metropolitan Circle and Changsha Metropolitan Circle, while the humanities protection areas are concentrated in Zhejiang, Anhui and Jiangsu provinces. The distribution of natural reserves is the most affected by resource endowment, while the humanistic protected land is closely related to urban development.
