摘要: 根据野外调查、文献和救护个体统计,四川省34个县(区)有黑颈鹤 (Grus nigricollis) 分布,其中繁殖地记录有10个县,迁徙地记录有24个县,未发现有黑颈鹤越冬地的记录。黑颈鹤在四川省的繁殖地有2个区域,一个是若尔盖湿地,这个区域是目前已知黑颈鹤繁殖最集中和数量最多的区域;另一个是川西高原的沙鲁里山,其繁殖种群分散,数量较少。黑颈鹤的繁殖地大多都已经被划为保护区,但保护管理还有待加强。对黑颈鹤繁殖的系统研究还不够深入,有待进一步加强。Abstract: According to field investigations, literature and crane rescue reports, the Black-necked Crane (Grus nigricollis) is distributed in 34 counties (districts) of Sichuan Province, including 10 counties with crane breeding and 24 counties with migrating. So far, the Black-necked Crane has not been found overwintering in Sichuan Province. The Black-necked Crane breeds in two areas in Sichuan Province-one is the Ruoergai Wetland which is famous for its high density and population of Black-necked Cranes during the breeding season; another one is Shaluli Mountains in the western Sichuan plateau where the Black-necked Crane breeding groups are scattered and small. Most of the breeding areas of the Black-necked Crane are protected and are in nature reserves,but the management of these nature reserves needs to be improved. The systematic breeding ecological study of Black-necked Crane is limited, therefore more and further research is needed.
