人工湖水生态系统构建方法研究

基于湖泊生态恢复的理论及工程实践经验,提出了新建人工湖水生态系统构建的一般方法。通过水生植物、水生动物的合理选种、水生植物的空间和时间配置以及水生动物食物网的合理构建,使各种群在整体上互补共生,形成结构合理、具有一定抵抗能力与自我恢复能力的水生态系统。以某新建人工湖为例,基于所提出的方法构建了其水生态系统。研究成果对人工湖水生态系统的构建和运行管理具有指导意义。

Study on the aquatic ecosystem design method of artificial lakes

Based on the theory and engineering practice of lake ecological restoration, a general method on creating aquatic ecosystem of newly-built artificial lakes was proposed. Through the reasonable selection of aquatic plants and animals, the appropriate spatio-temporal layout of aquatic plants, and the reasonable construction of aquatic food web, thus species could complement with each other as a whole and finally an aquatic ecosystem with rational structure, as well as certain resistance and self-recovery capabilities could be formed. Taking a newly-built artificial lake as an example, a proper aquatic ecological system was designed for the lake according to the method proposed in the paper. This method can play a guiding role in design and operation management of aquatic ecological system of artificial lakes.
