| 2016年9月至2017年4月，采用样线法和可变大小样方法相结合，对七里海潟湖湿地非繁殖期鸟类进行了调查研究。调查共记录到鸟类13目27科60种，其中雀形目鸟类10科14种，占物种总数量的23.33%；非雀形目鸟类17科46种，占物种总数量的76.67%。湿地水鸟数量占全部鸟类总数量的95.11%，水鸟类群主要为鸥类、雁鸭类、鸻鹬类和鹭类。鸟类居留类型主要为旅鸟和夏候鸟，分别占物种总数量的35.00%和33.33%。鸟类区系方面，以古北界鸟类和广布种鸟类为主，分别占物种总数量的63.33%和26.67%。经统计，鸟类多样性指数、均匀度指数和丰富度指数的平均值分别是1.86、0.39和2.31。七里海潟湖湿地位于东亚—澳大利西亚迁徙路线上，是重要的鸟类迁徙停歇地和觅食地，鸟类尤其是水鸟资源丰富，应当受到关注和保护。 |

| Abstract: |
| Bird diversity in the Qilihai Lagoon wetland of Qinhuangdao was investigated with line transects and variable circularplot methods during nonbreeding seasons from September 2016 to April 2017. A total of 60 species belonging to 13 orders and 27 families were recorded. Among the 60 species, 14 species in 10 families were Passeriformes, accounting for 23.33% of the total. The other 46 species in 17 families accounted for 76.67% of the total. Waterfowl population made up 95.11% of all the species and most of them were gulls and ducks, followed by waders and herons. For the residential types, passing migrants and summer migrants were the most abundant species, accounting for 35.00% and 33.33% of the total, respectively. In the avian fauna, Palaearctic realm species and widespread species accounted for 63.33% and 26.67% of the total, respectively. Based on the statistical analysis, ShannonWeaver diversity index, Pielou evenness index and Margalef richness index averaged 1.86, 0.39 and 2.31, respectively. The Qilihai Lagoon wetland, located on the east AsiaAustralasia migration route, is an important stopover and foraging site for migrating birds, especially for waterfowls. Thus, it should necessarily be concerned and protected. |
