Research on Poyang Lake Wetland Information Extraction and Change Monitoring Based on Spatial Data Mining

Poyang Lake wetland is the largest "kidney of the mainland". It plays an important role in many aspects such as water storage, flood control, climate mediation and biological diversity protection. This paper first reviews the development of wetland RS monitoring and probes RS classification methods based on Spatial Data Mining; secondly gives analysis on spectrum features of RS images of Poyang Lake wetland, and sets up the Decision Trees Model; and then classified RS image by Decision Trees Model in Expert Classifier module of Erdas Imagine 2010 software, and achieves a relatively high precision. Finally it gives dynamic change monitoring on Poyang Lake Wetland based on multi-temporal RS image and grasps the changed situation to provide scientific proof for government decision making.
