中文摘要 过度开发和休闲游憩等人类干扰导致湖岸带生境的均质化和退化,影响鸟类生存并制约湖泊湿地的生态服务功能。文章以重庆市梁平区双桂湖国家湿地公园为案例,对2019年实施“环境-生物-结构”协同设计的湖岸带修复工程4年后的鸟类群落及生境进行调查,结合生境制图法量化生境特征。结果表明:双桂湖湖岸带共有鸟类49种、实验区45种、对照区22种;实验区鸟类香农-威纳指数(北岸2.665、西岸2.984)高于东岸对照区(2.563),其中,西岸新增小微湿地面积较北岸更多,水鸟种类及其种群数量增加更为显著。鸟类多样性与生境多样性、鸟类数量与生境丰富度之间呈显著正相关关系(P＜0.01)。综上可知,修复工程有效促进了鸟类生境单元多样性的增加;构建湖岸带小微湿地和“林-草-湿”复合生境格局能使生境异质性和鸟类多样性得到持续提升。

英文摘要 Anthropogenic interventions like excessive development and recreational activities resulted in the homogenization and degradation of lakeshore habitats and exerted negative impacts on bird survival and ecological service functions of lake wetlands. Taking Shuanggui National Wetland Park in Liangping District, Chongqing, for a case study, the study investigates the bird communities and their habitats 4 years later after the lakeshore restoration project began to be implemented in 2009, which focused on the coordinated design framework of environmental elements-biological elements-structure, and quantifies the habitat characteristics using habitat mapping method. The results reveal that there are totally 49 bird species in the Shuanggui lakeshore, among which 45 species are observed in the experimental area and 22 in the control area; the Shannon-Wiener Index for birds is higher on the north shore (2.665) and the west shore (2.984) of the experimental area, compared to the east shore (2.563) in the control area. The west shore has a larger area of micro-wetland than the north shore, thereby with a more significant increase in both the variety and the population sizes of waterfowl species. There is a significant positive correlation between bird diversity and habitat diversity, as well as between bird abundance and habitat richness (P＜0.01). It is concluded that the restoration project has effectively increased the diversity of bird habitat units, and construction of small and micro-wetlands and integrated forest-grass-wetland habitat pattern have continuously improved the lakeshore habitat heterogeneity and bird diversity.
