陕西省历次水资源规划成果对比与思考

Comparison of achievement of previous water resources planning in Shaanxi Province

对比新中国成立以来陕西省开展的3次水资源评价和4次水资源供需分析研究成果发现,陕西省自产水资源量有减少趋势,供、用水结构发生了较大变化,同一水平年需水量大幅度减少,水资源利用效率和效益快速提高。揭示了水资源规划中存在的对经济社会发展速度估计不足、需水量预测偏大、用水效率估计偏低等问题。指出:应重视需水管理,坚持以水定产、以水定发展的思路;发挥水资源综合规划对开发利用的指导作用;重视水资源利用现状研究,开展典型用水调查;建立规划后评估制度,提升水资源规划水平。

Through comparison of 3 times of water resources evaluation and 4 times of supply and demand analysis carried out by Shaanxi Province since 1949, the self - produced water resources amount is decreasing and the structure of water supply and consumption has changed significantly. The water demand of the same year decreased dramatically, and the water efficiency and profit increased rapidly. The problems in the water resources planning are pointed out, including failing to predict the quick development of economy and society, larger predicted water demand, smaller predicted water efficiency, etc.. It is proposed that we should focus on the water demand management, stick to the concept of producing and developing based on water resources, realize the guiding role of water resources comprehensive planning in its development and utilization, pay attention to the study of water resources utilization status, conduct the typical water consumption investigation; the post evaluation system of planning should be established so as to improve the planning level.
