【摘要】：建立二维盐度数值模型,计算区域包括大通至长江口及其邻近海域,设计高分辨率网格,数值模拟和分析在不同大通流量等级下长江口盐水入侵形势,计算出中小潮期间长江口重要水库取水口处盐度均值为0.5‰时对应的临界大通流量。利用模型分析长江口盐度场对上游大通流量的敏感性。本文对临界大通流量的计算研究有助于提高预报长江口盐水入侵模型精度,为长江口水库避咸蓄淡提供参考;盐水入侵对流量的敏感性研究可以为改善盐水入侵情况提供技术指导。
[Abstract]:A two-dimensional salinity numerical model is established. The calculation area includes Datong to Changjiang Estuary and its adjacent sea areas. High resolution grids are designed. Numerical simulation and analysis of salt water intrusion situation in Yangtze Estuary under different Datong flow levels are carried out. The critical Datong discharge is calculated when the average salinity at the intake point of the Changjiang Estuary is 0.5 鈥，
