摘要
笔者以受到富营养化威胁的城市湖泊——惠州西湖为研究对象,针对其营养程度、生物多样性情况,从生态学角度制定湖泊生态系统管理规划。规划从西湖的环境特征角度出发,结合浅水富营养湖泊多态现象理论,以恢复高等水生植物群落构建为主,结合鱼类、底栖动物调控,削减营养负荷与优化湖泊管理,达到以高等水生植物为优势的、生态系统结构合理的、自净能力与抗干扰能力强的生态系统,最终实现西湖的稳态转换。
The research object is an apparent city lake what is threatened eutrophicationally in Huizhou West Lake. Aiming at lake nutrition degree and biology diversity, the lake ecosystem management and program are built from the point view of ecology. The management and programming start off from environment trait of West Lake, combine theory of superficial water rich nutrition and lake enjoying polymorphism. The key is that renewing and building high-level hydrophyte＇s community, combining fish and benthic animal - adjustment and control, cutting down nutrition burden and optimizing lake management. So the ecosystem can achieve advantage of high-level hydrophytes, logical and self-clean and anti-jamming strongly ecosystem. At last, the balance of lake transfer can be realized.
