摘要：

In order to realize high-precision, automatic abstraction and live, dynamic monitoring of wetland information in Poyang Lake Area, this study researches on RS image classification and change monitoring based on knowledge rules. It first reviews the development of wetland RS monitoring and probes RS classification methods based on Spatial Data Mining; secondly it gives analysis on spectrum features of RS images of Poyang Lake wetland and sets up the Decision Trees Model; and then it classifies 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 master the dynamic change to provide scientific proof for government decision making. © 2013 Asian Network for Scientific Information.
