title: [Discussion on some basic problems in design of wetland ecosystem].
abstract: 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 indicators 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.
