海水温度和盐度的变化与鱼类的行动和分布息息相关。当前在海洋渔业生产上广泛开展渔情预报工作,对发展海洋渔业生产,进行科学捕鱼作出了一定的贡献,而海水温、盐度的预报,往往是分析渔情,预测渔况和发布渔情预报的重要依据。本研究课题是直接为海洋渔业生产服务的,因而,我们主要选择渔汛期和渔场区进行了水温纵向预报试验。所谓纵向预报,这里是指多年同月水温序列的预报,借以同横向时间序列预报相区别。
Changes in seawater temperature and salinity are closely linked with the movement and distribution of fish. At present, the extensive work on the forecast of fishery conditions in the production of marine fisheries has made a certain contribution to the development of marine fishery production and scientific fishing. However, the prediction of sea water temperature and salinity often analyzes the situation of fisheries, forecasts the status of fishing and releases fisheries An important basis for forecasting. This research project is to directly serve the marine fishery production. Therefore, we mainly choose to carry out longitudinal forecast of water temperature in fishing season and fishery area. The so-called longitudinal forecast, here refers to the forecast of the series of water temperature for many years in the same month, in order to distinguish with the transverse time series forecast.
