摘要
通过１９９７０７２４～１９９７０８１７对四川辖曼自然保护区的调查，发现黑颈鹤２６９只．通过平均密度法估算整个保护区有４０７只，其主要分布在伏流宽谷沼泽和湖泊洼地沼泽，其最适生境是湿润及水体沼泽区，偶见于草坡．由于自然环境的变迁及人为活动的干扰，黑颈鹤的栖息繁殖环境及整个湿地生态系统的稳定性正受到极大的威胁。
According to the investigation in the Xiaman Nature Reserve in Sichuan from 24 July to 17 August,1997. 269 individuals of black necked Cranes were observed and it was deduced that there should be about 407 individuals by the method of average density .The habitats for black necked cranes in Xiaman were marshes, Lakes,and Occasionally grasslands. Because of the environmental changes and human activities, the distribution areas of black necked cranes have been greatly reduced in recent years.
