向海自然保护区鹤类生境优化的水量调控

Water Control for Optimization of Crane Habitat in Xianghai National Nature Reserve

在基于向海自然保护区湿地水位达到 16 5m ,鹤类可选择生境面积最大这一研究结果的基础上 ,利用区域水量平衡原理 ,计算了为维持这块鹤类生境面积的健康存在 ,需要从对向海自然保护区起重要水源调控功能的向海水库调出的水量 ,并根据研究区的实际条件 ,提出了研究区湿地生境安全的用水保障措施。

The contributors have done some research for the crane habitat of Xianghai National Nature Reserve, and have reached a conclusion that when the water level arises altitude 165 m, the selective crane habitat area can reach the maximum (981.2 hm 2). Based on this result, using regional water balance law, the authors calculate the removing water in order to reserve this crane habitat being healthy from the Xianghai reservoir which is very important for controlling the water of the wetland in Xianghai National Nature Reserve. Meanwhile present several effective measures for water utilization in order to reserve this crane habitat being safe.
