摘　　要：针对协同GIS对多用户地图编辑和长事务处理的协同需求,给出了基于任务划分的协同GIS工作模型;构建了协同GIS工作环境;结合多版本技术,解决了协同GIS中多用户对地理数据的协同编辑等问题.通过在国家863项目中的实践证实,该方案支持对共享数据更新操作的并行执行,减少了数据锁定的需求,实现了协同工作机制与GIS的结合,取得较好效果.Today's Geography Information System (GIS) can not only support one user but also can provide service for multi-users in a network environment. To support collaborative work among multi-users, the technology of Computer Supported Co-operative Work (CSCW)is depended on, the application of GIS is combined, and the Task-Based Cooperative GIS model is put forward. The core problems of building a Collaboration GIS are discussed and analyzed. At last, the solution is provided. Through applying the model to specific application domains, the prototype for the integration is implemented between CSCW and GIS.
