摘要
湖泊湿地是湿地的重要类型,在自然生态系统中发挥着涵养水源、滞污造淤、净水防蚀、调洪防涝、观光游赏、生物多样性维持等重要功能,是各种鸟类和底栖动物的栖息地。湖泊湿地依然存在着湿地遭受侵占、水体富营化、植被简单化、生物多样性降低、生态服务功能价值下降等问题,成为制约地方经济可持续发展的症结。该文通过查阅文献资料,剖析了各地湖泊湿地的生态退化的状况,归纳了湖泊湿地生态退化的环境诱因,评述了当前湖泊湿地生态修复工程中存在的问题与不足,并对未来湖泊湿地生态保护与修复研究工作提出了的策略和建议。
As an important type of wetland,lake wetland plays an important roles in the natural ecosystem,for instance,water conservation,pollution stagnation and silt prevention,water purification,erosion prevention,flood and waterlogging control,sightseeing and biodiversity maintenance,also acting as habitat of all kinds of birds and benthic animals.There are still a wide range of environmental problems in lake wetlands,such as wetland encroachment,water enrichment,simplification of vegetation,reduction of biodiversity and decline of ecological service function value,which have become the crux restricting the sustainable development of local economy.By the ecological conditions of wetlands vary greatly,and there is no unified restoration mode and practice for the lake and wetland ecosystem.Through the literature data,the ecological degradation of lakes and wetlands in various places was analysized,the environmental inducement of lake wetland ecological degradation summarized,the problems and deficiencies in the current ecological restoration project reviewed,and decision-making suggestions for the ecological protection and restoration work in the future were put forwand.
