黄海西部沿岸是我国人类活动和海洋经济开发较为集中的地带,陆地和海洋相互作用较为强烈,其特殊的地形和所处的独特地理位置,使得该海域的环流复杂多变,沿岸海域各水团与陆架锋以及长江口东北部的锋面一起构成了黄海西部特有的环流体系和背景场,对该海域的物质输运和扩散、海水运动以及海洋生物地球化学过程产生影响,并制约着沿岸海域对污染物的净化能力。在总结前人研究成果的基础上,较为系统地分析总结了黄海西部沿岸各流系或水团的配置、特性及其与传统上认定的黄海西部沿岸流主体的关系,在鲁南沿岸的流场布局、夏季江苏外海沿岸区域存在北向流等方面获得了一些新的认识,并阐述了各沿岸流系对物质输运的影响,分析了台湾暖流北上在物质输运中的作用。针对当前黄海西部沿岸流系定量研究中的不足,指出应通过建立沿岸流观测系统、采取新的技术手段和调查方式并利用相关数据挖掘技术分析现场调查和卫星遥感数据,提取出各水团及锋面的环境要素特征值,以此为基础模式,开展各沿岸流系的划分方法研究,判定陆架锋与黄海西部沿岸流的依存关系,建立沿岸流物质输运影响的评价方法,定量评估沿岸流物质输运扩散对近岸海洋环境的影响以及在物质收支循环中的作用,揭示黄海沿岸的自净能力与沿岸流物质输运的关系,为该区域海洋生态环境保护提供科学依据。
The western coast of the Yellow Sea is a relatively concentrated area for human activities and marine economic development in our country. The interaction between land and sea is more intense. Its special topography and unique geographical location make the circulation of the sea complex and changeable. And the front of the continental shelf and the northeast of the Yangtze Estuary, constitute the special circulation system and background field in the western Yellow Sea, affecting the transport and diffusion of matter, seawater movement and marine biogeochemical processes in this area and restricting the Purification of pollutants. On the basis of summarizing the research results of the predecessors, this paper systematically analyzes and summarizes the configuration and characteristics of each stream system or water mass in the western coast of the Yellow Sea and its relationship with the traditionally identified mainstream of the western Yellow Sea coast stream. Field layout and the existence of northward flow in the offshore Jiangsu coastal area in summer. Some influencing factors on material transport by the littoral banks are also described, and the role of Taiwan’s warm current northward in material transport is analyzed. In view of the current quantitative research on the western Yellow River flow system, it is pointed out that the establishment of a coastal flow observation system, the adoption of new techniques and survey methods and the use of relevant data mining techniques to analyze field surveys and satellite remote sensing data, Based on this model, we carried out a study on the division of flow along the coast, determined the dependence of the continental shelf currents on the continental shelf and the west coast of the Yellow Sea, established the assessment method for the influence of coastal transport of material flow, The impact of material transport and dispersion on the coastal marine environment and its role in the material income and expenditure cycle reveals the relationship between the self-purification capacity of the Yellow Sea coast and the transport of material along the coast and provides a scientific basis for the marine ecological environment protection in the region.
