| 摘 要： | 在盐城国家级自然保护区人工湿地内,通过对丹顶鹤越冬期间夜栖地的调查,得出鹤群夜栖分布及其动态规律,并提出对该种群与夜栖地的管理措施。该项工作主要借助望远镜、GPS.照相机,采用直接计数法统计数量和利用文献资料数据。结果表明:人工湿地中丹顶鹤的夜栖分布随着环境的改变而改变,其中安全度和水位为其主要限制因子。因此控制人工湿地冬季水位,保护栖息环境不受人为影响是丹顶鹤安全越冬的主要保护措施。

| Abstract: | Investigation was conducted on night habitats of wintering Red-crowned cranes in artificial wetland in Yancheng National Nature Reserve,in order to analyze the distribution of the night habitats and patterns of changes and to develop management measures for the population and their night habitats.Telescopes,GPS and cameras were used for the investigation.The number of cranes was determined by direct counting and literature data,The results indicated that the distribution of night habitats of wintering cranes changes with environment,among the environmental factors,safety and water level are the main restraining factors.Therefore,it is an important measure to control water level for cranes to have a safe wintering. |
