Constructed Wetlands for Wastewater Treatment

The Anjiashan wetland lies at N 28°14′, E 116°36′, its area is about 1.2 hm 2. There are 33 families, 60 genera, 79 species, one variety and one subspecies vascular plants. Of which, Isoetes sinensis and Oryza rufipogon are key protected plants in China, and Sagittaria wuyiensis is endemic rare species. As for life forms, most plants (59 species) are emerging plants and hygrophytes. The Anjiashan wetland is located in subtropic zone. The tropics floristic elements occupy adominant position at the level of species, although there are 24 cosmopolitan genera in this wetland vegetation. Because of environmental heterogeneity, there are few edificatoes, but many co dominant species in the vegetation. There are many rare plant species in Anjiashan wetland, so it is necessary to take measures to protect this wetland.
