Abstract:In order to improve the eco-environment service ability, enhance the biodiversity conservation function, and promote the construction and development quality of the wetland parks in Guangzhou, a plant diversity survey was conducted in twenty wetland parks recently. The results showed that total 205 aquatic and wetland plant species were recorded; the analysis to species composition, life form, habit, dominant family and genus and application frequency revealed that the community structure of the aquatic and wetland plants was relatively simple, the homogenization of the dominant species used was very serious, and the key protected and rare and endangered wild plants were seldom considered for conservation too. Therefore, fifty-five indigenous plants were recommended as candidate species for ecological promotion and landscape configuration in future. Finally, several suggestions were put forward for the future construction and management of wetland parks in Guangzhou.
