【摘要】 水鸟群落是湿地生态系统的重要组成部分，对环境变化具有高度敏感性，为了研究水鸟对降水的响应特征，2016—2021年持续对广西山口红树林国家级自然保护区水鸟进行监测。结果表明：（1）水鸟数量对降水量的响应具有季节性差异，春季和夏季水鸟数量与降水量呈现显著负相关关系（P<0.05），秋季和冬季水鸟数量与降水量呈现显著正相关关系（P<0.05）;(2)水鸟分布格局对降水量的响应亦有季节性差异，随着降水量的变化，水鸟在农用地与自然生境中迁移。更多还原

【Abstract】 Waterbirds community is an important part of wetland ecosystem, which is highly sensitive to environmental changes.In order to study the response characteristics of waterbirds to precipitation, continuously monitored waterbirds in Guangxi Shankou Mangrove National Nature Reserve from 2016 to 2021. The results showed as follows:(1)The response of waterbirds population to precipitation had seasonal differences.There was a significant negative correlation between the number of waterbirds population and precipitation in spring and summer(P <0.05), and a significant positive correlation between the number of waterbirds population and precipitation in autumn and winter(P < 0.05).(2) The distribution pattern of waterbirds also had seasonal differences in response to precipitation. With the change of precipitation, waterbirds migrated in agricultural land and natural habitat.更多还原
