The pollution control effect can be enhanced by the improvement of the design methods the components and management of constructed wetlands.The design methods aimed at controlling the stormwater runoff should be based on the hydrological data accumulated for years.The development of novel medium and the selection of plants i.e. flood-tolerant and economical should be considered in advance. The management of constructed wetlands should be enhanced and the database of the stormwater in wetlands should be built.The discussion above should be effective in improving the pollution control effect in stormwater runoff by applying constructed wetlands.展开更多
