Design and Implementation of Remote-sensing Monitoring and Assessment System of Wetland in Northeast China

The paper focuses on the typical wetland in Northeast China, in which region-dedicated design of virtual framework structure is adopted. Considering the characteristics of the wetland, and based on multisource remote sensing data, the remote-sensing monitoring and assessment business system for wetlands and wetland environment background database in Northeast China are established, the remote-sensing monitoring and assessment indicator system for wetland in Northeast China is confirmed, and the dynamic and continuous monitoring over the wetland is realized, and the service products are released real time, which have all provided scientific grounds for wetland protection, restoration and reconstruction, and the improvement of ecological environment.
