鉴于城市化地区水环境问题的时空复杂性,单一的水环境管理措施已不能满足实际管理的需要,为改善水环境有必要采取综合管理措施.文章以数字流域为基础,将流域内水系数据、地形数据、土地利用数据、社会经济及人口数据等进行融合,构建了水质综合管理决策支持系统,着重探讨了综合模型集成、动态空间数据与模型及管理之间的耦合关系问题;以深圳市石岩水库流域为例进行实证研究,构建了石岩水库流域管理决策支持系统,评价了旱季截污、产业结构调整、雨季截流等单个及组合措施的水质改善效果.结果表明该系统可以模拟多种措施的综合作用、动态的更新数据与模拟结果、并提供可视化的空间决策信息,是复杂流域水质动态综合管理与空间决策支持的有效工具.

Integrated management measures are necessary for improving water quality in a rapid urbanization catchment with temporal-spatial complexity in water environment. A framework of decision support system(DSS) for water quality integrated management was developed based on digital watershed technology. Coupling relationship among spatial data, modeling and management as well as model integration were discussed. In a case study of Shiyan Reservoir, Shenzhen, the effects of proposed individual and integrated measures were evaluated. Results indicated that DSS has capacity of simulating comprehensive effects of various management measures, dynamically updating data and simulating results, and providing visualized information for spatial decision making. The system would be an effective tool for dynamic management of water quality and spatial decision support.
