商洛市水资源供需分析及合理利用对策

ANALYSIS ON SUPPLY AND DEMAND OF WATER RESOURCES AND RELATED COUNTERMEASURES IN SHANGLUO CITY

随着人口增长和社会经济的发展,商洛市可利用的水资源已不能满足需水要求,供需矛盾更加尖锐。为了缓解商洛市水资源的供需紧张局面,在分析商洛市水资源开发利用程度的基础上,探讨了影响商洛市水资源开发的制约因素,主要包括供水工程供水能力不足、水污染严重及水资源利用效率低等原因,致使地区水资源不能有效地利用;以2005年为现状年,以2010和2020年为规划年,采用定额法对商洛市供需水量进行了预测,并对商洛市水资源进行了供需平衡分析,得出供水能力的不足是制约商洛市水资源供需平衡的关键;针对各制约因素,提出加快新修水源工程和供水工程建设、发展高效节水农业、建设节水城市及加大污水资源化等实现水资源供需平衡的有效对策,为商洛市的经济社会发展创造契机。

The utilizable water resources of Shangluo aren＇t sufficient to water requirement with the population and social economy development, and the contradiction between water supply and water demand is changing into more acute. Based on the development and utilization of water resources of Shangluo, for mitigating the tension of water supply and water demand, the restricting factors of water resources were studied, including the shortage of water supply, declining water quality and low utilization efficiency of water resources. Taking 2005 as a basic year, the water demand and water supply volumes in year 2010 and 2020 were forecasted by using quota method, and the balance between water supply and water demand in Shangluo was analyzed. It shows that the shortage of water supply is the key restricting factors of water resources. Then according to the restricting factors, the utilization countermeasures and measures of realizing the balance between the water supply and water demand are proposed by construction the new source engineering, development of water-saving agriculture, construction water-saving urban and increasing reuse of sewage, which are creating chance for the social economy development.
