人工湿地系统植被构建方式探讨

Discussion on the Establishing Methods of Vegetation in Constructed Wetlands

植物是人工湿地系统的核心之一,不但有助于污水净化,还能产生一定的生态环境效益。湿地运行初期植物的生长好坏直接影响到今后植物的生长和污染物的去除效率。面对新建的人工湿地,如何快速高效的构建植被系统,是工程建设中必须面对的一个重要问题。湿地植被构建方式的改进有助于提高湿地建设效率,改善系统处理效果。本文从工程角度探讨植物种植方式、种植时间、种植密度及湿地启动对湿地植被构建的影响。

As one of the main parts in a constructed wetland, the plants contribute not only to wastewater purification, but also produce benefits for ecological environment. The growth condition of plants during the initial operation of a wetland affects directly on their future growth and the removal efficiency of pollutants. For a new constructed wetland, how to build the vegetation system speedily and efficiently is important in the project construction. Improving the methods of vegetation construction can contribute to enhance the efficiency of construction and treatment for the whole system. This paper discusses on the factors in the fields of projects construction affecting vegetation of wetland including methods, time and density of planting as well as start mode.
