A STUDY OF THE ALTERNANT-MODE MODEL OF THE WATER RESOURCES EXPLOITATION AND UTILIZATION AND THE COORDINATIVE MANAGEMENT OF REGIONAL ECONOMY
水资源开发利用与区域经济协调管理的一种交互式模式

The water resources system consists mainly of surface and ground water. In this paper, the water resources system is resolved into the surface water system and the ground water system, according to the theory of the multi-level optimal control of a large-scale system. A multiple-objective management model is given for the surface water system, and an economic management model is developed for the ground water system. Then a coordinative function is designed in order to coordinate the surface and ground water systems. So, the total water resources system is operated by the optimal strategy. Various agricultural, industrial and life demand departments are considered in the regional economy. A decomposition-coordination optimal management model is developed for the demand water system. Finally,the total coordinated function is designed in order to coordinate the supply water system and the demand water system. So, the optimal operational strategy is provided for the total water resources system and the regional economic system.
