摘要

黄河自1976年改道清水沟流路,向东流入菜州湾以来,至1988年10月其大嘴已向莱州湾淤进18.8km(钱意颖等,1992),在科氏力的作用下,黄河入海口门也已转成东南方向。随着黄河口海区的开发利用,国内有关单位对黄河口海区的水文环境作过多次调查(朱兰部等,1994;张经等,1985;孙秉一等,198;Yang Zuosheng et al.,1989),从这些调査资料中我们发现,黄河入海径流和长江口一样,在洪水期冲淡水也有转向东北方向的特点。本文根据1976年黄河改道以来中国科学院海洋研究所有关单位在黄河口海区进行调查的水文资料和利津水文站的黄河径流观测资料,对黄河冲淡水的转向现象及其成因进行初步的分析研究,此研究对深入了解黄河口的水文环境及河口有机物、溶解质、悬浮体的输运特征有重要意义。

Abstract

Hydrological investigation data were used to analyze the characteristics of the salinity distribution and the extenion of the Yellow River Diluted Water (YDRW) in the sea. After the Yellow River relocatid eastward to Laizhou Bay in 1976,it was found that the YDRW extends east ward and northeast ward during the plentiful water period (from June to October), and southeast ward during the dry season (from November to May). The main factors affecting the extension direction of the YRDW were found to be theYellow River runoff, monsoon and current systems near the Yellow River Estuary. The critical value of discharge which makes the YRDW turn eastward or northeastward is 2.2×109m3 per month.
