【摘要】 由于城镇生活、工业和环保用水的增加以及灌溉面积的扩大,都江堰水资源的需求量亦随之增加。到2030年,都江堰灌区需要的引水量将达到岷江可引水量的极限,即岷江金马河河段将处于长时间断流的状态,对生态环境和人文景观都将产生不利的影响。本文分析了都江堰水资源利用的发展趋势,重点探讨了水资源供需矛盾的解决方案,包括合理利用地下水、开展人工增雨、合理利用邻近流域的水资源等。这些措施将有助于解决都江堰水资源总量缺乏和水资源量的时空分布不均匀的矛盾。更多还原

【Abstract】 The demand of water resource of Dujiangyan increases along with the extension of the irrigation area and the increase of water usage in urban living,industry and environment-protection.Till 2030,the water demand of Dujiangyan irrigation area will reach the maximum water from Minjiang river.Thus,the Jinmahe section of Minjiang river will remain dry for a long time. It will bring the disadvantageous effect on the local environment and cultural sight.The development tendency of water resource and the methods to solve the contradictions between water resource supply and demand is presented in this paper.The measures of making use of the underground water,transferring water from near basin and development of rainmaking should be helpful to decrease the spatial and temporal non-uniformity of water resource and the shortage of water supply in Dujiangyan.更多还原
