水生植物对水体修复的作用研究及其品种选择

Study on the Role of Aquatic Plants in Water Restoration and Variety Selection

水生植物作为水生态系统中重要组成部分,对水生态系统修复起着重要作用,主要有为其他生物提供食物及栖息场所;过滤、吸附和沉降;吸收、富集作用;光合增氧作用;化感抑藻作用。上海地区自然条件适宜各类水生植物,按照沉水、浮叶、漂浮、挺水植物四类,从种类形态、净化效果、养护栽培要求三个方面总结品种选择要求,指导水生植物的配置设计。

Aquatic plants which are as an important part of water ecosystem, play an important role in the restoration of water ecosystem. Main functions of aquatic plants include providing food and habitat for other organisms, functions of filtration, adsorption and settlement, functions of absorption and enrichment;photosynthesis providing oxygen, allelopathy can inhibit the growth of algae. Natural conditions are suitable for all kinds of aquatic plants in Shanghai. Aquatic plants are classified into submerged plant,floating-leaved plant, floating plant, emergent aquatic plant. This paper summarizes the requirements of variety selection from three aspects: species morphology, purification effect, maintenance and cultivation requirements, and guides the configuration and design of aquatic plants.
