摘　　要：2011年12月～2012年3月,采用样线法对大丰麋鹿保护区幼龄麋鹿的集群组成、生境选择和警戒距离等进行调查,采用目标动物取样法对其行为进行观察,分析处于乏食状态下幼龄麋鹿的行为活动规律。结果显示:幼龄麋鹿昼间77.45%的时间用于取食活动,它们通过延长取食时间以取得足够食物,维持生理需要。乏食压力下,幼龄麋鹿集群、生境选择及观望警戒距离月间差异均不显著(P>0.05),生活规律保持相对稳定性。乏食期结束,74.58%的幼龄麋鹿能够应对自然环境变化得以生存,显示了其具有一定野外生存本能和较高的环境变化适应能力。From December 2011 to March 2012,we investigated herd composition,habitat selection and alert distance of young Pere David＇s Deer（Elaphurus davidianus） using the line - transect sample method in Dafeng Milu National Nature Reserve. We observed the behaviors of young Pere David＇s Deer under the pressure of insufficient food using the target animal sampling method.Young deer spent 77%of daylight hours in foraging and they spent more time to obtain enough food to maintain the physiological need.Group size,habitat selection and alert distance of young deer did not differ under conditions of insufficient versus sufficient forage（P0.05）.Three of four young deer survived on insufficient forage,indicating ability to survive in the wild and adapting to changing environments.
