The design and realization of Heilongjiang provincial flood control decision support system

Heilongjiang Province is one of the biggest inland provinces in China. There are few large control reservoirs to prevent great floods in its main rivers. So it faces more difficulties and increased loads in flood control. The flood control decision support system is a very important part of nonstructural measures in the practice of flood control. This paper analyzes the framework of Heilongjiang Provincial flood control decision support system, which integrates all flood control tasks, such as collection and transaction for information, flood forecast and flood control operation, decision making consultation, and so on, into a whole system. And two main subsystems are discussed and designed in details, i.e. the information service subsystem, decision making consultation subsystem. They focus on some content about the main functions, network architecture, key techniques and system realization. At present the system is running normally and has played an important role in flood control of Heilongjiang Province.
