水生植物不仅能够使园林景观变得丰富多彩,而且还能使受污染的水体得到一定程度的净化。本文以成都活水公园为例,总结分析出水生植物的应用种类和植物配置等相关问题,以及对人工湿地中水生植物净化作用的探讨。通过前人对活水公园净化效果的数据分析可以看出,对污染物的去除上都保持着较高的去除率,超过设计指标,并且优势水生植物对污染物的去除率不尽相同,总的来说是芦苇>香蒲>伞草。 Aquatic plants not only make landscapes rich and colorful, but also allow the contaminated water to be purified to some extent. Taking Chengdu Huishui Park as an example, this paper summarizes the application of aquatic plants and plant configuration and other related issues, as well as the purification of aquatic plants in constructed wetlands. According to the data analysis of purification effect of living water park, the removal rate of pollutants is higher than that of design index, and the removal rates of pollutants by dominant aquatic plants are different.
