【摘要】 水资源是基础性的自然资源和战略性的经济资源,水已被列为五大可持续发展世界性课题之首,对水的关注主要体现在三个领域:水与发展、水与环境和水的管理。对水与发展和水与环境的强烈关注反射出水资源在可持续发展中的基础性地位和至至关重要的作用,不恰当的水的管理可能是诱发各种水问题的主要原因。加强对水的管理,实现水资源可持续利用,保障经济社会可持续发展,已成为一种全球性共识和正在世界范围推广的实践。文章通过对泾惠渠灌区社会经济历史资料的分析,采用“哈罗德—多马”模型,预测灌区一定水平年社会经济发展的各项指标,通过定额法推求灌区工农业及生活需水量,在分析确定灌区水资源开发潜力的基础上,按照“节水为先,需水控制、开源节流相统一”的思路,建立水量供需平衡分析数学模型,研究确定藻区供水优化调度方案。即:建立节水型农业生产体系,提高水的利用率;采用地表水与地下水联合调度,维持水资源的良性循环;加强用水管理,提高水的经济效益。该成果应用于灌区管理,对缓解灌区水量供需矛盾、拟制灌区地下水位下降、提高灌区工农业生产水平、保持灌区社会经济协调发展将起到积极的促进作用。更多还原

【Abstract】 Water is a basic natural resource and national strategically economic resource. The issue of water has been listed as the first of world top five main issues which concern the durable development. The care on water issues is mainly focused on the following three aspects: water and development, water and environment, and the management on water. The strong care on water & development, and water & environment reflects the fundamental position and essential function of water resources in the social durable development, and unsuitable management on water resources may be one of the main reasons causing various problems and conflicts concerning water resources. So, to strengthen the management on water resources, realize the durable utilization, and to ensure the social durable development has become a common understanding and been being fulfilled worldwide. By analyzing the concerned social and economic data in history in JingHui irrigation area, and by utilizing "Harold—Thomas" pattern, the article predicts each main indexes of social and economic development in a certain coming years; by analyzing the rated unit consumption for industrial and agricultural activities, works out the water demand in both industrial & agricultural, and living aspects; on the bases of analyzing the potential resources of water in the irrigation area,a mathematical model of balance of water supply and demand has been established in the spirit of "Saving water being the first, controlling the demand, and exploiting the potential and saving water both being important" to further study and optimize the water dispatching scheme in the irrigation area, i.e., to establish a low water consumption agricultural production system, enhance the efficiency of water utilization, optimize the dispatching of both ground and underground water to maintain a positive water recycling, and strengthen the water management to enhance the economic efficiency by utilizing water. To utilize the study result in the irrigation area will play a positive and constructive role in softening the conflict of water supply/demand, controlling the going down of underground water table, improving the industrial/agricultural production, and maintaining the harmonious development of the social and economic in the irrigation area.更多还原
