Decision Support System for Water Quality Integrated Management Based on Digital Watershed Technology:A Case Study of Shiyan Reservoir in Shenzhen

HAN Long1,2,QIN Hua-peng1,2,LU Nan3,HU Jia-dong3 (1.Key Laboratory for Environmental and Urban Science,Shenzhen Graduate School,Peking University,Shenzhen 518055,China;2.Shenzhen Key Laboratory of Environmental Simulation and Pollution Control,Shenzhen 518057,China;3.Shenzhen Water Pollution Control Headquarter Office,Shenzhen 518036,China)  
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.
