将单位产值能耗模型应用于区域用水量预测中,提出了水资源总量的约束条件,在基准情景、优化情景、可持续发展情景三种情景下,预测分析了2010～2050年河北省用水量。通过与河北省水资源评价中不同水平年的用水量预测值比较,表明本文模型的预测值准确性较高,切合实际情况,可持续发展情景能满足区域水资源总量的约束要求,为适合今后水资源和社会经济发展的最优情景。
The energy consumption per unit of output value model is applied to the prediction of regional water consumption, and the constraints of the total amount of water resources are put forward. Under the three scenarios of the baseline scenario, the optimized scenario and the sustainable development scenario, the water consumption of Hebei Province from 2010 to 2050 the amount. Compared with the predictive value of water consumption in different years of water resources appraisal in Hebei Province, it shows that the predictive value of this model is accurate. According to the actual situation, the sustainable development scenario can meet the requirements of the total water resources in the region and is suitable The best scenario for water resources and socio-economic development in the future.
