【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]:The spatial distribution characteristics of National Wetland Park in China were preliminarily analyzed by means of mathematical statistical method, geographical statistical model and GIS spatial analysis method. The results showed that: (1) the spatial distribution of the National Wetland Park was unbalanced, and the distribution of the National Wetland Park was concentrated in the middle, Shandong Peninsula and the Yangtze River Delta. 2 from the distribution of the provinces and municipalities, the National Wetland Park was concentrated in Hubei and Shandong. Heilongjiang, Hunan and other provinces form four high-density hot spots in southwest Shandong, northwest Jiangsu, southern Jiangsu, northern Hunan and eastern Hubei. 3 from the point of view of the spatial distribution of natural geography, the National Wetland Park is concentrated in the subtropics. In the middle temperate zone and warm temperate zone, the annual average precipitation is 800 mm and 400 mm, as well as the area below 1 500m elevation. 4 from the spatial distribution of ecological regionalization, the National Wetland Park is concentrated in the Yangtze River region and Songhua River region in the first class watershed. The Huai River region, the Yellow River region and the wet areas of the middle and lower reaches of the Yangtze River and the wet areas of the middle and lower reaches of the Yellow River in the eight wet areas. 5 from the perspective of the social and economic spatial distribution, the National Wetland Park presents a pattern of "more in the middle, more in the west and less in the east". Correlation analysis shows that the number of National Wetland Park and the land area of each province and city area, The correlation between GDP and resident population is not strong (r = 0.160.26 and 0.39 respectively) 6 the development of National Wetland Park at present mainly depends on the resource background condition, the enthusiasm of local declaration and the degree of attention to the development of Wetland Park.
