景观水体生物种群构建与水质控制探讨

Construction of biological population in landscape water and water quality control

水体景观是现代景观设计中的重要表现形式之一,随着"生态绿化"理念的发展,景观水体日益成为公共绿地的重要组成部分。因其相对封闭和面积较小,生物链不完整,生态稳定性差,水体富营养化现象较为普遍。应用生态学原理,在水体构建浮游生物、水生植物、鱼类以及底栖生物组成的生态系统,辅以调控措施,维持水体生态平衡,可提高景观水体的自净能力,维持良好的水质和景观效果。

Waterscape is one of the important forms of modern landscape design. With the development of the concept of Eco-greening,landscape water increasingly becomes an important part of public green space. Due to its relatively closed and small area,incomplete biologic chain,poor ecological stability,and common eutrophication phenomenon. Using the ecological theory,an ecosystem consisting of plankton,aquatic plants,fishes and benthic organisms is built in water,and the ecological balance in water is maintained with the aid of the control measures,so as to improve the self-purification ability of landscape water,and maintain good water quality and landscape effect.
