The development of environment friendly, efficient and economic reagents for soil remediation; The ecological management of soil environment;

Responsible for the development and management of test project. 100mu field in Chenzhou City, Hunan Province was selected as our experiment location, and representative cadmium polluted paddy field was identified as the demonstration object for demonstration from 2013 to 2015. Evaluation of heavy metal pollution and potential ecological risk were conducted until ultimately determined the demonstration site for two years of remediation. In order to form a more systematic remediation evaluation system, repairing effect and their affect on soil quality were also evaluated and compared, respectively. Moreover, remediation mechanisms has been analysed.
