长江大通站水文系列的组成与感潮段主副港预报研究

本文根据大通站水文系列组成的分析,提出了长江感潮段潮位的主、副港预报方法和原理。主港为河口的吴淞和湖区界的大通;副港为沿江各港(站),建立了一系列多元回归函数预报副港的潮位,精度符合要求。

Method of Multiple Regression Function Between Primary Port and Secondary Port for predicting Tidal Level at Lower Reach of the Yangtze River

This paper mainly describes for predicting tidal levels at lower reach of the Yangtze River by analyzing the components of hydrologic series of Datong, where is the place located at the tidal flow limit of the river in Anhui province, the essay points out that the method of forecasting by multiple regression function between primary port and secondary port is a way to forecast the components that represent the stochastic or random variations. Owing to simultaneous presence of ocean tidal action and fresh water there are two primary ports, one is wusong at the mouth of the river and the other is Datong, the secondary port is along the tidal reach any one, where the tidal levels forecasting is desired. For most purposes to utilize the tidal energy as the pump stations along the river with optimal operation, irrigation, navigation, industrial water supply, drainage and for long distance mass transfer of water, the computation model therefore is satisfy for all year round.
