在中国2003年到2011年供需水量的基础上,建立GM(1,1)模型预测2025年中国各省市(除台湾,香港,澳门之外)的供水量和需水量,得出西北和沿海部分区域缺水的结论。为了解决缺水区的用水问题,需将丰水区的水向缺水区转移与调运,通过建立线性规划模型实现总费用最小化。该策略将有利于实现我国水资源的可持续利用。
Based on the water supply and demand in China from 2003 to 2011, the GM (1,1) model was established to predict the water supply and water demand of all provinces and cities in China (except Taiwan, Hong Kong and Macao) by 2025, and the Northwest and Coastal Parts Regional water shortage conclusion. In order to solve the problem of water shortage in the water-deficient area, the water in the water-rich area needs to be transferred and transferred to the water-deficient area. The total cost should be minimized by establishing a linear programming model. The strategy will be conducive to the sustainable use of water resources in our country.
