摘　　要：传统流域决策支持系统往往使用一两个模型来解决某些特定目标,限于系统结构而不能综合考虑多领域问题。提出了一种新的支持多学科模型集成的流域决策支持系统原型,在一个系统中实现多种学科模型的跨时空尺度集成,为流域综合管理提供全面科学支持。系统采用开放式多学科模型管理方法,其脚本扩展机制使得系统可以容纳几乎所有模型,模型因子方法使得形式多样的科学模型模拟结果可以应用到决策方法中,使系统在多学科模型支持下提供科学合理的决策方案。情景驱动的决策流程、向导式交互界面及GIS等图形化工具支持使得系统用户界面友好、易用性强。As watershed management involves multidisciplinary sciences including not only natural physical science but socio-economic science, a good practice generally should take into account multidisciplinary model integration so as to bring together their individual strengths to solve complex watershed problems encountered. Decision Support System （DSS） plays an important role in watershed management in helping decision makers evaluate water resources scenarios and make optimal decisions by applying latest achieve- ments of scientist community to management practices. Traditional DSS is insufficient to solve multidisci- plinary problems because it usually acts like a toolkit containing a single or several models and is not de- signed to address model integration issues. In this paper, a new DSS prototype supporting multidisciplinary model integration is proposed. A node-link based approach is adopted to enable technical integration of models with different temporal and spatial scales. By introducing the definition of compound node, the system can theoretically be extended to model arbitrarily complex watershed problems. In the underlain layer, the model library is implemented by a flexible script mechanism and can include any model with small＇modifications to encapsulate original model. A multiple criteria decision method is implemented to support evaluation of decision scenarios, through a special design that links model outputs to decision indicators. In view of common obstacles to optional run, this paper also highlights our consideration and implementation of a scenario-driven conceptual decision making flow, GIS supports, and easy to use for user interface such as wizard-style scenario setup steps.
