摘　　要：本文报道黄腰柳莺Phylloscopus proregulus的繁殖生态和种群动态,内容包括营巢环境、巢、卵、孵卵、育雏、雏鸟的发育,种群繁殖力、繁殖成功率和种群数量及变动。The breeding ecology and population dynamics of the Yellow-rumped willow warbler,Phylloscopus proregulus,were investigated during 1984-1985 at the Lenglong Mountain areas in Gansu province.The Yellow-rumped Willow Warbler arrives at the Lenglong Mountain areas on May 13-14 every year.Their pair-formation starts from last ten-days period of May to early June.The female goes to share with the male in building their nest for 4 days.They builded their nests on the ground under smaller shrubs in the dragon-spruces forest.The nests are like the half ball in the shape,the size of 7 nests averages 4.4±0.32cm in the exterdiameter,3.6±0.27cm in the interdiameter,3.5±0.41 in the bight and 4.1±0.21 cm in the depth.There are 4-5 eggs in a clutch.The eggs are white jade in color with rufous-red specks.The size of 14 eggs averages 14.9(14-16)×11.7(11.5-12)mm.and weight averages 0.81+0.02g.After the last egg was layed,the female begins fo incubate,the incubated period lasts 10-11 days.The female goes to share with the male in brooding their nestlings.The period resided by the youngs in the nests lasts 10-11 days.According to Ricklefs’method,the growth curve of body weight of the youngs is fitted the Logistic equation,W=6311/1+6-03892(t-3.45)T10;04.91 days.The breeding rate was 2 and the rate of the breeding success was 0.86.The successful rate of laying 4 eggs was higher than that laying 5 eggs.It has connection with the cower temperatures on June 1-151984,so the population density in June of 1985 was greater than in June of 1984.
