谈到黄河断流时,普遍认为始于1972年。其实黄河断流的现象早已见于记载。据《今本竹书纪年》,周贞定王六年(公元前463年),“河绝于扈”,黄河曾经在扈(今河南原阳县西)一带断流。 黄河断流主要是由于干旱引起的,如西晋永嘉三年(公元309年)五月全国大旱,“河、洛、江、汉皆可涉”,黄河和其他大河都可以涉水而过;黄河决口改道后,由于河水溢出或流入新的河道,也会使下游断流。如清道光二十二年(1824年),黄河在桃源县(今江苏泗阳、泗洪县)十五里堡、萧家庄决口,主流夺六塘河入海,使萧家庄以下河道断流。 断流一般发生在黄河下游,但个

As Qing dynasty twenty-two years (1824), the Yellow River in Taoyuan County (now Jiangsu Siyang, Sihong County) fifteen Fort, Xiaojiazhuang burst, the mainstream wins Liu Tanghe into the sea, so Xiaojiazhuang the following river break flow. The cutoff generally occurs in the lower reaches of the Yellow River, but one
