摘要
湿地生态系统设计是恢复、调整湿地的重要手段 .本文从湿地生态系统设计概念入手 ,阐述了设计的基本原则 .较详细地讨论了设计中的指标 (水文指标、化学指标、基质指标和生物指标 )要求 .根据湿地生态系统设计的用途不同 ,探讨了 3种主要的湿地生态系统设计类型 ,即作为废水处理湿地的设计 。
The design of wetland ecosystem is the key and fundament in wetland restoration and mitigation. In recent years, it has been frequently applied to the proper construction of wetlands. The paper first reviews the concept of wetland ecosystem design, as well as the basis of ecological engineering, and then presented the basic principles in the design of wetland ecosystem .Some major ecological indicators including hydrology, chemical, substrate, soil and biotic indicatiors were also discussed,and some reference values for ecological indicators were presented.On the base of the designing purposes,three major types in the wetland design were analysed. They include constructing wetlands for wastewater treatment, for mitigation wetlands, and for controlling flooding and non point source pollution.
