摘    要::作者1996年4~7月在紫蓬山区国家级森林公园,对白鹭、池鹭和夜鹭繁殖种群的数量和繁殖成效进行了研究。结果表明:三块样地中,夜鹭的种群平均密度最大,白鹭的种群平均密度最小;白鹭、池鹭和夜鹭的种群繁殖生产力分别为2374ind/hm2、1441ind/hm2和2012ind/hm2;繁殖成效分别为520%、551%和451%。繁殖成效与巢位高度有关,低位巢卵损失率高,高位巢雏丢失率高。

关 键 词:  繁殖种群  种群密度  繁殖成效

Abstract:This study was carrisd out at Zipeng Mountain National Forest Park from April to July in 1996.Population number and breeding success of chinese Pond Heron,Little Egret and Black-crowned Night Heron Were reported The averge population density of Black-crowned Night Heron was gerates,that of Little Egret was lowest.The reproductive productivity of the Chines Pond Herons was 237.4 ind/hm 2,that of Little Egrets 144.1 ind/hm 2 and that of Black-crowned Night Heron 201.2 ind/hm 2.Breeding success rate was 52.0%,55.1% and 45.1% accordingly.Breeding success was related to the height of the nest sites,and influenced by weather.
Keywords:Heron  Breeding population  Breeding success
