安徽沿江浅水型通江湖泊湿地是东亚—澳大利亚迁徙水鸟的重要越冬地和停歇地。近年来，高强度的渔业养殖使湿地严重退化，对越冬水鸟构成威胁。为了解湿地变化对越冬迁徙水鸟的影响，2007年11—2008年4月和2008年11月—2009年4月, 对安徽菜子湖和升金湖11个样带内越冬水鸟的种类、数量及空间分布进行了调查，并分析了湖泊渔业模式对水鸟分布的影响。两个湖泊共统计到越冬水鸟7目12科43种。其中, 菜子湖群38种, 密度为8.2 ind./hm2; 升金湖42种, 密度为3.5 ind./hm2, 优势种为鸿雁(Anser cygnoides)、豆雁(Anser fabalis)、小天鹅(Cygnus columbianus)和黑腹滨鹬(Calidris alpina )。越冬水鸟种类和数量在12月底—次年1月上旬达到最大值, 但不同类型越冬群最大数量出现的具体时期有所不同。根据水鸟组成的聚类分析, 可将水鸟栖息地分为三组。水鸟的分布与渔业模式有关，在自然捕捞区, 鹤类、雁鸭类和鸻鹬类密度较大，在围网养殖区密度较小，而鹭类的密度在各湖区变化都较小。本研究结果提示, 发展可持续渔业对于长江中下游浅水湖泊湿地越冬水鸟资源的保护具有重要意义。
The shallow lake wetlands in the middle and lower Yangtze River ?oodplain are important wintering and stopover habitats for migratory waterbirds on the East Asia-Australia Flyway. With increasing fishery practices in recent years, however, the wetlands have deteriorated significantly and now threaten wintering waterbirds. To gain insight into the influence of deteriorating wetlands on waterbirds, we conducted a survey of wintering waterbird species, population size, and distribution across 11 belt transects in Caizi Lake and Shengjin Lake, two shallow lakes along the Yangtze River in Anhui Province from November 2007-April 2008 and from November 2008-April 2009, respectively. The impacts of different fishery patterns on the distribution of waterbirds were also analyzed. A total of 43 waterbirds species belong to 7 orders of 12 families were counted during the surveys, of which 38 were found in Caizi Lake with a density of 8.2 ind./hm2, and 42 in Shengjin Lake with a density of 3.5 ind./hm2. Geese (Anser cygnoides), bean geese (Anser fabalis), tundra swan (Cygnus columbianus), and dunlin (Calidris alpina) were the dominant species in the two shallow lakes. Species number and individual assemble reached maximum at the end of December and in early January of the following year, without coincidence of the largest flock for different ecological groups. Based on waterbird diversity across the 11 belt transects and the fishery patterns, habitats could be divided into three groups. Gruiformes, Anseriformes and Charadriiformes had relatively higher densities in the natural fishery zones and lower densities in the cage fishery zones; whereas, the density of Ardeidae showed little change across all lake zones. It is important to develop sustainable fishery patterns in shallow lakes along the middle and lower Yangtze River floodplain to better protect resources of wintering waterbirds.
