| 摘 要： | 现代黄河三角洲由几个亚三角洲组成。 1 85 5 -1 93 4年 ,形成了以宁海为顶点的第一亚三角洲 ;1 93 4-1 996年 ,三角洲冲积扇顶点进一步下移 ,形成了以渔洼为顶点的第二亚三角洲。最近的一次改道是在 1 996年 6月 ,改道后的河流沿清水沟流路的清 8剖面附近东流入海。这次改道可能是第三亚三角洲形成的开始。以后数十年内的黄河尾闾摆动将在清 8剖面附近进行。虽然人类活动将对三角洲的发展演化产生越来越明显的影响 ,但这些亚三角洲的发育演化仍有明显的规律性

| Abstract: | The modern Yellow River delta consists of several subdeltas. The first subdelta with an apex near Ninghai was formed during 1855 to 1934, and the second subdelta with an apex near Yuwa was formed during 1934 to 1996 due to the further downstream shift of the delta apex. The latest river diversion occurred in June, 1996, and the diverted river flowed eastward into the sea around the Qing 8 section. The diversion may be the beginning of the third subdelta formation, and the terminal channel of the Yellow River will swing around the Qing 8 section in several decades. Although the human activities will bring about increasing influences on the development and evolution of these subdeltas, there are still obvious regularities in the development and evolution of these subdeltas. |
