本文以1978—1982年浙江省海洋水产研究所秋、冬汎嵊山、大陈渔场水文调查资料为主要依据,分析了北纬28°—31°、东经125°以西海城内,四个纬向断面水温的逐月分布和变化。4—11月,表层水温比底层高,且在上均匀层下面存在着梯度层。水温存在垂直梯度层现象,本文泛指为水温层化。为了便于分析,本文以各断面梯度层强度大小作为分析水温层化时空变化的依据。在探讨水温层化与渔业生产关系时,整理了同期有关渔业的统计资料。
In this paper, based on the hydrological survey data of Zhejiang Province Institute of Marine Fisheries in Autumn and Winter, Shengshan Mountain and Dachang Fisheries from 1978 to 1982, the four zonal sections Monthly water temperature distribution and changes. From April to November, the surface water temperature is higher than the ground floor, and there is a gradient layer below the upper uniform layer. There is a vertical gradient of water temperature phenomenon, this article generally refers to the water temperature stratification. In order to facilitate the analysis, the strength of each section gradient layer as the basis for analysis of temporal and spatial changes of water temperature stratification. When discussing the relationship between water temperature stratification and fishery production, the statistical data on fisheries in the same period were compiled.
