摘要
泥流既是泥石流的一种特殊类型,也是水土流失极严重的一种形式。我国泥流主要分布于晋西北、陕北、陇东及陇西等黄土高原腹地。泥流在将大量泥沙搬运出黄土高原,输向黄河引起下游河床严重淤积的同时,对农业生产、城镇工矿、交通运输、水利水电工程、山地环境和人民生命财产等也造成严重危害。提出了泥流灾害防治中应遵从的6项基本原则。
Mudflow is a special category of debris flow hazards and a form of serious soil erosion as well. Mudflow mainly distributes in the Northwestern Shanxi, Northern Shaanxi, Eastern Gansu and Western Gansu four regions on main body of the Loess Plateau. A great number of sediments are transported by mudflow from the plateau and cause serious silting and aboveground rivers on the lower reaches of the Yellow River and its main branches. Meanwhile,it generates great dangers to agriculture, cities, towns and mining regions, railways, highways, and oil and natural gas pipelines,reservoirs and hydropower stations, mountain environment and lives and properties of the people in the Loess Plateau. At the end, six prevention countermeasures of mudflow hazards are put forward.
