Abstract: Based on the analysis of the geological formation of the coal mining subsidence area, the habitat characteristics of the built area and the habitat conditions of the area to be built of Jiuli Lake, the plant remediation technology with simple operation, less investment and no secondary pollution was planned for the polluted water and soil in Jiuli Lake coal mining subsidence area. The stems and leaves of plants transported oxygen from the air to the roots, forming an aerobic environment conducive to nitrification and denitrification by microorganisms, which could accelerate the absorption of nitrogen and phosphorus by plants. Wetland plant planning should firstly simulate the natural wetland plant community, in order to build wetland animal habitat, enhance biodiversity, and strengthen the stability of the wetland ecosystem.

Key words: constructed wetland, ecological restoration, hydrophyte, water purification, biodiversity
