Study of Panjin Wetlands Along Bohai Coast:(Ⅰ) the Information System of Wetlands Based on 3S Technique

Based on previous studies on Panjin wetlands along the coast of the Bohai Sea,this paper adopts RS,GIS and GPS tech-niques and establishes the information system for Panjin wetlands. The system involves many functions,such as identification and classification of wetlands,calculation of the area of wetlands and storage of the information of the wetland management. Moreover,our study indicates that remote sensing technique is a useful tool for great macrography,speediness and accuracy to carry out the extraction,analysis,management and handling of information together with geography information system,which has prospective applications in similar kinds of research.
