| 摘 要： | 根据1984—1990年的考察结果,兴凯湖自然保护区丹顶鹤的数量为59—62只,其中繁殖的有14—15对;没繁殖的有9—10对;一年龄幼鹤13—14只。1987—1990年间,共调查了20个巢,产卵40枚,出雏36只。而同期的秋季考察中共记录了本区繁殖家族14对,共存活13只幼雏。每个家族平均0.93只幼鹤。本区适宜生存的面积仅150平方公里,经7年调查最大容纳量(K值)稳定在60只左右,平均每只占区2.4—2.5平方公里。

| Abstract: | According to the result investigated in 1984-1990,there were 59 to32 Red Crowned Cranes in the Xingkai Lake Natural protected Area. And 10 couples unreproduced, 13 to 14 were one-year-old of age. 40 eggs in 20 nests investiagted during 1-987 to 1990 were laied and among them 36 had nestlings. 14 couples of reproducing familes were recorded during the same period in fall and 13 young birds lived, by an average 0.92 young bird lived in each family. In the Xingkai Lake Natural Protected Area,
where is suitable for living i only 150 Sq.km. After 7 years' investigation, it was found that the highest capacity of the crane's number was steady about 60 ones and each one occupies an area of 2.4-2.5 Sqkm on an average. |
