【摘要】 为保障上海市长江口水源地的供水安全,并为流域的水资源规划提供依据,在对长江口咸潮入侵特征进行分析的基础上,根据上海市长江口各水源地的供水能力,明确了保障上海市长江口水源地供水安全分月控制临界流量的涵义和标准。根据陈行取水口实测资料采用统计模型,并结合多盐度数学模型的计算成果,综合分析确定了咸潮入侵期(10月至次年4月)各月的临界流量过程,并提出了长江口水源地咸潮控制监界流量保障措施建议。更多还原

【Abstract】 In order to guarantee the water supply safety of water source area in Yangtze River estuary for Shanghai City and provide basis for water resources planning of the Yangtze River Basin,the meaning and standard of monthly controlled critical flow for water supply safety are made clear based on the analysis of the characteristics of saline water intrusion of water sources and its water supply ability.The monthly critical flow process from October to next April in the saline water intrusion period is determined using statistics model,combing with the calculation results of mathematical model of multi-salinity,according to the measuring data of Chenxing water intake.The guarantee measures for critical flow of saline water intrusion into water sources area of Yangtze River estuary are proposed.更多还原
