摘    要:1985、1995年和1998年4-5月,采用查阅保护区历史资料及实地调查方法,对辽宁双台河口国家级自然保护区内丹顶鹤(Grus japonensis)的主要营巢地-东郭苇场和赵圈河苇场的生境破碎化及丹顶鹤在2片苇场中的营巢状况和繁殖种群数量变动情况作了系统的考察和研究,发现丹顶鹤的营巢生境破碎严重,已由成片的芦苇湿地变成91个斑块,其中最小营巢斑块面积为0.37km^2,最小巢间距为304m,比过去资料记载的最小巢区面积缩小了0.72km^2,但繁殖种群数量变动不大,多年来一直维持在30对左右,丹顶鹤为了适应变化了的环境,已采取了缩小巢区面积的生态适应对策。

关 键 词:丹顶鹤  生境破碎化  巢位选择

Abstract:During April and May of 1985,1995 and 1998, red crowned crane's nesting and variation of breeding population quantities in Shuangtaihekou National Natural Reserve in Liaoning,and also the habitat fragmentation there were investigated. Associated with previous data of the reserve, red crowned crane's nesting habitat had been seriously fragmentated into 91 patches from one integrated reed wetland.The area of the smallest patch was 0\^37km\+2,and the minimum distance of two nests was 304m.Compared with records of previous data,the minimum area of nesting habitat reduced by 0\^72km\+2.However,the breeding population quantities of red crowned crane had maintained at about 30 pairs for a long period.The red crowned crane adapted to the changed environment by the ecological adaptation strategy of reducing area of nesting habitat.
Keywords:Red  crowned crane  Habitat fragmentation  Nest site selection
