| 摘 要： | 本文报道了紫蓬山区池鹭、白鹭和夜鹭雏鸟的生命表，并对三者的存活曲线进行了比较，结果表明，池鹭、白鹭和夜鹭雏鸟分别在９－１３、８－９、１１－１４日龄的千分死亡率较高，０日龄期望的雏期分别为１７．９７、２３２０、２４．７７天，存活曲线都为Ａ型，但池鹭雏的最凸，夜鹭雏的最四三种鹭雏鸟的生命表和存x活曲线的研究对于了解雏鸟存活情况，以及制定种群的保护措施具有重要的意义．

| Abstract: | This paper deals with life tables and survivorship curves of nestling Chinese Pond Heron,Little Egret and Black-crowned Night Heron in Zipeng Mountains.The nestling of Chinese PondHeron has higher qx from 9 days old to 13 days old. In the case of nestling Little Egret and Black crowned Night Heron, qx.is higher from & days old to 9 days old, and from 11 days old to 14 days oldrespectively. At 0 day old,life expectancy of the nestling of Chinese Pond Heron, Little Egret andBlack-crowned Night Heron is 17.97 days, 23.20 days, and 24.77 days respectively. All of thesurvivorship curves are A-patterns, of which the curve of nestling Chinese Pond Heron projects more,however that nestling life tables is helpful to get information about survivorship of the nestling, and totake measures to conserve these birds. |
