上海西郊淀山湖湿地生态修复探析

Analysis of Ecological Restoration of Dianshan Lake Wetlandin the Western Suburbs of Shanghai

随着我国经济的发展和城市化进程的加快,资源破坏和生态环境恶化问题日益突出。上海西郊淀山湖区域(黄浦江上游水源保护区的核心位置)承载着自然生态保育、水源保护与涵养、生态防护等基本作用与功能,变化的自然环境导致了该功能不断退化,对该区域湖泊湿地进行保护和修复,维护水源地生态安全迫在眉睫。本文从"上海西郊湿地建设可行性研究报告"调查分析了一些场地历史资源和现状问题,结合示范区工程实践,对工程实施中植物群落修复配置、水系建设和鸟类等动物环境栖息地保护等措施做出介绍和总结,探索建立人工植物群落的自我维持机制和人工调控技术,以形成具有整体性、稳定性的湿地生态景观,最终实现生态恢复、水质自净、生物多样化及人与自然的和谐共生。

With the acceleration of China's economic development and urbanization process,the problems of resources destruction and ecological environment deterioration have become increasingly prominent.The Dianshan Lake area in Shanghai western suburb(the core position of Huangpu River upper stream water conservation district) carries the basic functions of ecological conservation,water resource protection and conservation,ecological protection,etc.However,changes in the natural environment has led to the continuous degradation of these functions.As a result,protection and restoration of the lake wetland in this area to maintain the ecological safety of water sources has become extremely urgent.According to 'Shanghai Western western suburb wetland construction feasibility study report',this paper investigated and analyzed the historical resources and current situation of the sites;introduced and summarized the measures of plant community restoration configuration,water system construction and animal environment habitat conservation combining with the engineering practice of demonstration area;explored the selfsustaining mechanisms and artificial regulation technology of artificial plant community to form the wetland ecological landscape that has integrity and stability;finally to realize the goal of ecological recovery,water self-purification,biological diversity and the harmony between human being and nature.
