摘要：Under the joint action of the Yangtze River Basin and Xiangjiang River Basin,Dongting Lake has caused irreversible heavy metal pollution to the surrounding wetland soil,and has brought about ecological,atmospheric and water natural pollution.In view of the main method to solve the heavy metal contaminated soil is the biological agriculture and forestry combined ecological restoration method,this paper takes the soil polluted by heavy metal in Dongting Lake wetland as the research object,and constructs multiple groups of comparative experiments with indoor potted plants as the object.In order to provide theoretical and technical support for improving and repairing the polluted soil in Dong-ting Lake wetland,ryegrass and Thiobacillus fer-rooxidans were used as the objects of phytoremediation respectively to explore the method of phytoremediation combined with both of them,and to explore the effect of the method of Phytoremediation on the remediation of heavy metal pollution in soil.
