To meet the urgent needs of desertification monitoring in the Tarim River watershed,it established desertification and model da-tabases for the early warning monitoring system and WEBGIS in the study area based on an integrated framework of the VB+SuperMap Objects (C/S) and the c#+SuperMap IS. NET (B/S). By using the observed data and the prediction model for early warning,the results showed that around 90% prediction accuracy could be achieved. The proposed system can provide an efficient storage and organization for multivariate GIS data in relational database,and the real time monitoring system of the field sand collection could improve the per-formance of the system. The proposed system is originally developed for the downstream of the Tarim River watershed. Due to the univer sality,the system can support decision making for related government departments and researchers,and has played an important role in practice.
