长江冲淡水和台湾暖流是我国陆架海上两个重要的海洋现象。二者在长江口邻近海域交汇并相互制约,其分布和变化控制着该地区的温盐、环流结构,也影响着长江径流所携带的泥沙、营养盐等物质向外海的扩散和输运,以及舟山渔场的形成和变化。 长江每年以巨量径流注入东海,在长江口外形成一股很强的冲淡水,以低盐、高营养盐、高悬浮体含量为特征。毛汉礼等(1963)首先对长江冲淡水的扩散与混合特征作了系统的描述,并指出,冬季长江冲淡水沿岸南下,其范围仅限于贴岸的一狭带内;夏季则在径流入海后不久转向东北,直指济州岛方向,到达对马海峡。众多学者通过资料分
The Yangtze River flushing water and the warmth of Taiwan are two important marine phenomena on the shelf and sea of our country. Both of them converge and restrict each other in the vicinity of the Yangtze River estuary. Their distribution and changes control the temperature, salt and circulation structure in the area and affect the diffusion and transport of sediment and nutrients carried by runoff from the Yangtze River into the open sea. As well as the formation and change of Zhoushan Fishing Ground. The Yangtze River flows into the East China Sea with a huge amount of runoff each year, forming a strong flushing water outside the mouth of the Yangtze River. It is characterized by low salt, high nutrient salts and high suspended matter content. Mao Hanli et al. (1963) first described the characteristics of the diffusion and mixing of the freshwater in the Yangtze River. It pointed out that in winter, the red water of the Yangtze River goes south along the coastline, and its scope is limited to a narrow band affixed to the shoreline. Shortly after runoff into the sea in summer Turn to the northeast, directed Jeju Island direction, reach the horse Strait. Many scholars through the information points
