摘  要:
采用固定监测样点、样线对向海保护区迁徙丹顶鹤种群数量动态变化、分布区域及栖息生境进行监测,结果表明:2003年以后,保护区内迁徙种群数量相对降低,而自2010年起未再观察到繁殖巢,迁徙种群数量总体呈下降趋势。主要原因是湿地长期干旱,生态系统退化严重,特别是作为丹顶鹤繁殖生境的芦苇沼泽不仅面积小,而且破碎化严重,不能满足丹顶鹤繁殖对水位、湿地面积及隐蔽条件等最低需求。人工辅助湿地生态系统恢复、建立永久性调水工程等是解决问题的有效途径,从而恢复和发展丹顶鹤种群。

摘  要:
The dynamic change,distribution area and habitat of migrating Grus japonensis population quantity of Xianghai protection zone was monitored by using fixed monitoring sampling point and line. The result showed that migrating population quantity of protection zone was low after 2003 while the breeding nests were not observed from 2010. The migrating population quantity presented decline tendency. The main reasons were long time drought,the ecosystem degenerating seriously,especially the area of reed swamp which was regarded as Grus japonensisbreeding habitat was small and the fragmentation was serious which can't satisfy the lowest need of water level,wetland area and shelter condition for Grus japonensis breeding. The human assistance wetlands ecosystem recovery,establishing permanent water transfer project were the effective approach to solve the problem. It can recover and develop Grus japonensis population.
