Wetland area classification and accuracy evaluation of Poyang Lake based on remote sensing

This paper was primarily conducted to probe into the method and approach which could improve classification accuracy of wetland, made experiment of the computer automatic classification methods to Landsat TM Image covering Poyang Lake wetland. In experiment firstly used unsupervised classification to remote sensing image, made progress of manual work interpreted to make certain their attributes, then transformed their outcome to the file of classification cyclostyle, and then carried out supervised classification, it indicated that the classification precision of Poyang Lake wetland was improved through these means.
