【摘要】 对盐城自然保护区丹顶鹤及其栖息地现状及变化进行了研究.结果表明,1999年保护区丹顶鹤调查数量为796只,主要栖息地为农田、苇草滩和盐蒿滩,丹顶鹤数量分别占总数的37.19%,23.37%和16.96%.70%的丹顶鹤分布于保护区核心区及附近面积为200hm~2的区域.对丹顶鹤栖息地的选择性的分析表明,在丹顶鹤的主要栖息地中,对农田和苇草滩具有明显的正选择性.根据1982年以来的资料分析,由于自然环境条件的变化及人类活动的影响,丹顶鹤的栖息地的类型,分布及选择性都有明显的变化.更多还原

【Abstract】 The Current status and change of Red - crowned Crane and its habitats were studied. In 1999, the number of Red - crowned Crane in Yancheng Nature Reserve is 796. Its main habitats are farmlands, grassy tidal lands and Saltliving wormwood lands. The number of Red -crowned Crane in these habitats is 37.19% , 23.37% and 16.96% respectively. More than 70% individuals distribute in the core area and sounding region with area about 200 km . Study on the habitat selection of Red - crowned Crane shows that Red - crowned Crane has positive selectivity to farmlands and Grassy tidal lands. Analysis on the data from 1982 indicates that the habitat type, distribution and selectivity of Red - crowned Crane changed obviously for the influence of nature environment and human development activities.更多还原
