Development and application of decision support system for real-time regulation and control of water environment

By taking the establishment of the decision support system for real-time regulation and control of water environment as the object，so many modules，such as the comprehensive data monitoring system，the database，the load model of river basin pollutants discharged into river，the river water environment model，the water environment bearing capacity and pollution load dynamic regulation and control model，GIS platform，etc.，are integrated，and then the general framework for the system composition is proposed herein，for which the key links of the system integration，i.e. the method for integrating and linking among several mathematical models，the method for interacting between GIS platform and mathematical model，the real-time simulation of the status of water environment，the simulation of the regulation and control measures-based scheme，etc.，are analyzed as well，thus the concept and method for realizing the real-time regulation and control of water environment and the digitalized management function within a large complicated system are put forward，which provide a simple and practical integration mode for developing and integrating the regulation and control system for complicated water environment. The result from the application of this system to the management of the water environment of the North Canal water system shows that the system realizes the simulation of the real-time regulation and control of the North Canal and enhances the intelligentized management level of the regional water environment. The study result has an important reference value for establishing the real-time regulation and control and the decision support system for water environment as well as the refined management concerned.
