采用环志的方法,对朱野外种群进行了6年研究,编制了生命表;并对其繁殖地点变动、繁殖情况及各年龄组的存活情况等现状做了分析,发现洋县朱种群中,当年幼鸟死亡率比较高。增加种群数量的关键是保护1龄幼鸟。
Abstract:An investigation of the natural poptilation of Crested Ibis(Nipponia ,nippon)has been con-ducted for 6 years by means of banding ,and the life table of the precious bird has been work out. Atthe same time,the nesting sites,reproducting ecology,and the survival rates of different age stageshave also been studied.The investigation results show out that 1-year-nestling has a relatively higherdying rate in the population of Crested lbis in Yangxian County, Shaanxi Province. Hence conserving1-yeflrnestliiig is key measurement for inlarging the Crested Ibis population.
