摘要
利用数理统计方法、地理统计模型和GIS空间分析方法,对中国国家湿地公园的空间分布特征进行了初步分析.结果表明:①国家湿地公园空间分布不平衡,总体上呈现凝聚型分布,集中分布在中部、山东半岛和长三角.②从省市区分布来看,国家湿地公园集中分布在湖北、山东、黑龙江、湖南等省份,并在鲁西南-苏西北、苏南-浙北、湘北、鄂东形成4个高密度热点区域.③从自然地理空间分布来看,国家湿地公园集中分布在亚热带、中温带和暖温带,年平均降水量800~1 600 mm和400~800 mm区域,以及高程1 500 m以下的区域.④从生态区划空间分布来看,国家湿地公园集中分布在一级流域中的长江区、松花江区、淮河区和黄河区以及八大湿地区中的长江中下游湿地区、黄河中下游湿地区.⑤从社会经济空间分布来看,国家湿地公园呈现"中部多、西部较多和东部相对较少"的格局.相关分析表明,国家湿地公园数量与各省市区的国土面积、GDP和常住人口数量的相关性不强(r分别为0.16、0.26和0.39)⑥现阶段国家湿地公园的发展主要取决于资源本底条件、地方申报的积极性和对湿地公园发展的重视程度.
Abstract
By using the methods of mathematical statistics, geographical statistical model and GIS spatial analysis methods, the spatial distribution characteristics of China national wetland parks were preliminarily investigated. The results show that①The spatial distribution of national wetland parks appeared uneven. As a whole, they presented the condensed type distribution, intensively distributed over Central China, Shandong Peninsular and Yangtze River Delta.② From the viewing angle of distribution numbers wetland park in each provincial, municipal and district, the national wetland parks intensively distributed over Hubei, Heilongjiang, Hunan, etc., and formed 4 high-density hot regions in Southwest Shangdong+Northwest Jiangsu, South Jiangsu+North Zhejiang, North Hunan, East Hubei.③ From the viewing angle of spatial distribution of physical geography, the national wetland parks intensively distributed over the subtropical, temperate and warm temperate zones, interspersed among the regions with average annual precipitation of 800~1600 mm and 400~800 mm, and the regions with the elevation below 1500 m.④ From the viewing angle of spatial distribution in ecological regionalization, the national wetlandparks intensively spread alongfirst level river basins, such as Yangtze River Region, Songhuajiang River Region, Huaihe River Region and Yellow River Region, and wetland regions of the middle and lower reaches of the Yangtze River and the middle and lower reaches of the Yellow River within China eight large wetland regions.⑤From the viewing angle of spatial distribution in social economy, they presented the pattern of"many in central China, more in west China, and relatively less in east China". The correlation analysis results indicate that the correlation indexes between the national wetland parks number and land area, GDP and the numbers of resident population of all provinces were not high (r=0.16, 0.26 and 0.39, respectively).⑥ The current development for national wetland parks mainly depends on resources base conditions, enthusiasm of local declaring qualification of national wetland park, and the attention degree to develop national wetland parks from local governments.
