摘要
为推进南水北调工程的高质量发展,分析了南水北调东线江苏境内受水区现状节水措施及成效,从生活、农业、工业三方面确定节水潜力研究方法,提出预期可达的节水目标并计算了受水区节水潜力,根据“先节水后调水”的原则,确定了南水北调东线工程江苏段调水量,对节水的经济、社会及生态效益进行了分析。研究结果表明:南水北调东线江苏境内受水区2030年节水潜力为15.91亿m^(3),主要节水潜力在农业方面;与常规方案相比,基于节水潜力挖掘的优化调度方案下泵站总抽水量减少28.31亿m^(3),可降低泵站能耗5427.74万kW·h,节水经济效益达27.59亿元。
To promote the effective development of the South-to-North Water Diversion Project,taking the water receiving area in Jiangsu as the research object,the current water-saving measures and effects are analyzed,and the research methods for water-saving potential are determined from three aspects of life,agriculture and industry.Based on the achievable water-saving target,the water-saving potential is calculated.According to the principle of“water-saving first and then water transfer”,the dispatching scale of the eastern route project of the South-to-North Water Diversion Project in Jiangsu is determined,and the economic,social and ecological benefits of water-saving are analyzed.The research shows that the water-saving potential of the water receiving area in Jiangsu is 1.59 billion m^(3) in 2030,and the main water-saving potential is in agriculture.Compared with the conventional scheme,the total pumping volume can be reduced by 2.83 billion m^(3) under the optimal water-saving scheduling scheme,which can reduce the energy consumption of the pumping station by 54.28 million kW·h,and the water-saving economic benefit reaches 2.76 billion yuan.The research results provide ideas for further optimizing the allocation of water resources in the water receiving areas of Jiangsu in the eastern route of the South-to-North Water Diversion Project and implementing the policy of water control in the new era.
