人工湿地在盘锦市水环境生态规划中的作用

The Roles of Constructed Wetlands in the Eco-construction of Panjin City

生态城市的建设依赖于科学利用有限资源。随着我国城市化进程加快，水体污染日益严重，加剧了水资源的短缺。人工湿地是利用生物自净功能，低投入、低运行费、低能耗的环保型的污水处理技术。不仅可进行水资源的循环利用，而且美化环境、保护生物多样性。本文分析提出，人工湿地是生态城市建设中水资源利用最有效模式，应大力发挥人工湿地在我国生态城市建设中的作用。

Ecocity construction depends on scientific uses of limited resources .With the rapid development of urbanization, water pollution timely becomes a serious problem and water scarcity is concerned in China .Constructed wetland system is an efficient bio-technique for wastewater purification with low investment, imbecility, low circulation fee and high ecovalue. Water can be recycled in the system and it provides natural habitats for organisms and better environments for human beings. Therefore, constructed wetland system is almost efficient mode for water use with ecological and social service functions in the sustainable human settlements. We suggest that utilization of constructed wefland in domestic ecocity construction should be strongly encouraged.
