摘　　要：为研究池衫湖富营养化后生态系统的变化情况,根据2018—2019年池杉湖湿地采样数据和文献资料,构建了池衫湖生态系统Ecopath模型,主要包括10个功能组。结果表明:目前池杉湖湿地生态系统总初级生产量/总呼吸量(TPP/TR)值为2.829,表明池衫湖生态系统仍不成熟,总体处于发育阶段;通过Ecopath模型将氨氮和COD浓度增加5倍和10倍模拟预测池衫湖富营养化后生态系统的变化,随着氨氮与COD的增高,生态系统食物链受到破坏,生态系统功能逐渐丧失。池衫湖生态系统正处于发育阶段,富营养化会使生态系统的食物链受到破坏,对于冬季鸟类排放大量粪便引起的富营养化应采取适当的管理措施,以保障池衫湖生态系统的健康发展。In order to study ecosystem changes in Chishan Lake after eutrophication,the Ecopath model of Chishan Lake ecosystem was established based on the field data collected from the Chishan Lake wetland from 2018 to 2019 and literature data,mainly including 10 functional groups.The results showed that the current Total Primary Production/Total Respiration(TPP/TR)of Chishan Lake wetland ecosystem was 2.829,indicating that the ecosystem was still immature and at the development stage;in this study,the concentration of ammonia nitrogen and COD was increased by 5 and 10 times through the Ecopath model to simulate and predict ecosystem changes after eutrophication of Chishan Lake,and it was found that the food chain of the ecosystem was disrupted and the ecosystem functions were gradually lost with the increase of ammonia nitrogen and COD.The Chishan Lake ecosystem is at the developmental stage,and eutrophication will destroy the ecosystem food chain.Appropriate management measures should be taken for the eutrophication caused by a large number of feces discharged by birds in winter to ensure the healthy development of the ecological system in Chishan Lake.
