摘要
利用地理集中指数、均衡度指数、均衡比指数等定量方法,从东、中、西部和11省市尺度对长江经济带1066个自然保护区分布特征进行了综合分析。结果表明:(1)保护区数量和面积分布均衡性存在空间差异;(2)保护区在东部主要受经济状况影响,中部受人口数量影响,西部受省市面积影响;(3)森林生态类在中部和西部分布均衡,野生动物类在东部和中部分布较均衡,野生植物、古生物和地质遗迹在西部分布较均衡,内陆湿地在中部分布较均衡;(4)市级和国家级保护区分布较集中,县级和省级保护区分布相对均衡;草原草甸和海洋海岸类分布较集中,内陆湿地、野生植物和森林生态等分布相对均衡。研究成果可为优化研究区自然保护区空间格局,拟定自然保护区发展政策提供依据。
Based on the geographical concentration index, equilibrium index and equilibrium ratio index method, this paper comprehensive- ly analyzed the distribution characteristics of 1066 different grades and different types of nature reserves in the Changjiang Economic Zone from two scales of the east to the west and 11 provinces and cities. The results showed that： （1）There were differences in the distribution of the number and area of the natural protection areas. The distribution of the central part was more balanced while was poor in the eastern, and the distribution of the western part was more balanced, but the area distribution was quite different. （2）The distribution of nature reserves in the east was affected by the economic situation, the middle was affected by the population quantity, and the west was affected by the measure of area. （3）The distribution equilibrium of different types of nature reserves was different, and the forest ecological types were balanced in the central and western regions, while the wild animal types were more balanced in the eastern and middle parts. Wild plants, ancient biological relics and geological relics were more evenly distributed in the western regions. The inland wetland typos were more balanced in the middle regions. （4）The distribution of different levels and types of nature reserves in 11 provinces and cities was different, and the distribution of municipal and national protected areas was more concentrated, and the distribution of countylevel and provincial protection zones was relatively balanced. Grassland, meadow and marine coastal types nature reserves were more concentrated, while the inland wetlands, wild plants and forest ecological types nature reserves were relatively evenly distributed in various provinces and cities. This study could provide an academic basis for optimizing the spatial pattern of nature reserves, formulating the development policies of reservation parks, and constructing ecological civilization in the Changjiang Economic Zone.
