摘要
洪泽湖我国五大淡水湖之一,其湿地生态系统对淮河下游以及南水北调东线工程的水环境质量有重要的调节功能,由于受过境客水和季风气候的影响,形成5种湿地类型,且湿地生物多样性和生物资源极其丰富。文章在分析洪泽湖湿地生态多样性特征的基础上,分析了洪泽湖湿地存在生物多样性减少、湿地功能减退、水质下降等多种生态环境问题,认为洪泽湖湿地水位剧变、水质恶化等人为因素和自然因素是导致洪泽湖湿地功能和生物多样性退化的主要原因。
As one of the biggest freshwater lakes,Hongze Lake plays an important role in the water environment quality of Huaihe River＇s lower reaches and south-north water transfer east route project. It forms five types of wetland landscape due to the influence of the cross-boundary water and monsoon climate. Its biodiversity and biological resources is extremely rich. Based on investigating the characteristics of ecological diversity in Hongze Lake,the purpose of the study was to discuss the major eco-environmental problems of the Lake wetland,such as wetland biodiversity loss,wetland disfunction and deterioration of water quality. Results indicated that the main reason is human activities and natural factors,such as the change of water depth and deterioration of water quality.
