洱海湖滨带的生态现状与修复措施

目前洱海富营养化、水质恶化、生态系统退化等环境问题加剧,致使湖泊生态系统的良性循环遭到破坏,尤其是洱海流域内最敏感和脆弱的湖滨带区域,生态破坏更为严重。为了从一定程度上缓解这一现状,本文在洱海湖滨带的生态现状调查和湖滨带生态修复理论的基础上,介绍了湖滨带生态修复和重建的相关技术。结果表明：湖滨带在涵养水源、蓄洪防旱、促淤造地、净化水体、维护生物多样性和保持生态平衡等方面有着十分重要的作用。湖滨带生态修复的总体目标是要建立过渡带结构。健康的、具有自我维持能力的湖泊生态系统是湖滨带生态恢复与重建工作的最终目标。

Current Ecological Situation and Ecological Restoration measures in Lakesied zone of Erhai Lake

At present,there are many environmental problems of Erhai Lake such as eutrophication,deteriorative water quality and degradation of ecosystem which led to the breakage of positive circulation of Lake ecosystem.Among these areas,the breakage of ecological was especially serious in the most sensitive and vulnerable Lakesied zone of Erhai.In order to smoothen this current ecological situation to some extent,this paper introduced the technology related to the ecological restoration and reconstruction of Lakesied zone of Ernail based on current ecological situation of which and theory of ecological restoration.The results indicated that Lakesied zone embodied many functions such as preserving water resource,resisting flood and drought,creating terra,purifying water quality,maintaining biology diversity and keeping the ecosystem equilibrium etc.The total target of ecological restoration was establishing the transitional structure.The ultima target of ecological restoration and reconstruction of Lakesied zone was creating healthy and autarkic lake ecosystem.
