| 中文摘要 | 云南东北部的小江流域是我国暴雨型泥石流集中发育的地区之一。在小江众多的泥石流支沟中蒋家沟是爆发最频繁、规模最大、危害最严重的一条泥石流沟。 蒋家沟泥石流至今已有三百余年的历史。 |
| 英文摘要 | The mudflow of the Jiangjia Ravine, Dongchuan District, Yunnan Province, is one of the typical large-scale mudflow in China. With a frequency of "bursting" 10 to even more than 20 times each year, it has a maximum discharge of 2420 m3/sec., a maximum velocity of 15 m/sec. and a maximum density of 2.37 tons/in3.It is caused by several natural parameters, such as peculiar geological structure and hydro-meteorological feature which are conducive to mudflowing. Yet, the most important one is human factor-the destruction of forest vegetation in large areas. The mudflow had its origion only about 400 years ago. Since then, according as the forest being cut over rapidly, the mudflow has accelerated in proportion, resulting in an intensive gully-dissection in the upper reaches and a continuous thick deposition in the lower reaches. |
