摘要: 2018—2023年越冬期,对菜子湖的水鸟资源进行调查,共记录到水鸟7目12科59种,其中,国家一级保护动物5种,国家二级保护动物9种。对水鸟取食集团群落结构进行分析,结果表明,不同取食集团水鸟群落多样性指数存在显著差异,不同类型多样性指数变化幅度是Shannon-Wiener多样性指数>Margalef丰富度指数>Simpson优势度指数>Pielou均匀度指数。不同取食集团水鸟的数量对水位变化响应存在一定差异,其中,食鱼组、食草组、食底栖动物组的数量与水位之间存在显著负相关关系,水位变化对水域、草本沼泽、泥滩等3种生境的面积具有显著影响。未来应从水位优化调控入手,维持越冬期水鸟丰富食物资源,对提高菜子湖水鸟群落多样性具有重要意义。

Abstract: During overwintering of the years 2018-2023, a total of 59 species of waterbirds belonging to 12 families and 7 orders, including 5 species of first-level nationally protected waterbirds and 9 species of second-level nationally protected waterbirds, were recorded. The results showed that there were significant differences in the diversity indexes of waterbird communities among different foraging guilds, and the change range of diversity index for different types was Shannon-Wiener Diversity Index > Margalef Richness Index > Simpson Dominance Index > Pielou Evenness Index. The response of waterbird populations in different foraging guilds was different to water level changes. Among them, there was a significant negative correlation between the populations of fish-eating group, sedge-eating group and invertebrate-eating group and water level. Water level changes had significant impact on the area of three habitats: water body, grassland and mudflat. In the future, water level regulation should be optimized to maintain abundant food resources for overwintering waterbirds, which is of great significance for improving the diversity of waterbird communities in Caizi Lake.
