摘　　要：2006-2009年,对三峡库区长江干流及12条主要支流的冬季水禽分布状况进行了较为系统的调查,其中鸳鸯的总体数量大约为100~120只.水位变动对鸳鸯的分布格局造成一定程度的影响,随着三峡大坝不同工程阶段的分期蓄水,三峡库区长江主河道的越冬鸳鸯种群数量呈明显减少趋势.2009年1月和2010年1月的调查结果表明,蓄水达172 m和168 m水位线后越冬鸳鸯集中分布于3条支流河道中,长江主河道中未见有越冬鸳鸯分布.From 2006 to 2010,a survey was made of bird distribution during the winter season along the course and bank of the Changjiang River and 12 tributaries of the Three Gorges Reservoir.The result showed that the fluctuation in water level influenced,to some extent,the distribution status of the overwintering population of mandarin duck（Aix galericulata）.The total population of mandarin duck numbered 100-120.The overwintering mandarin ducks disappeared in the river course of the Changjiang River after the water level rose to an altitude of 172 m and 168 m,and they were distributed mainly in 3 tributaries of Chanjiang River in January of 2009 and 2010.
