Abstract历史上曾经发生或根据判别因素综合分析确定今后有可能发生泥石流的沟谷,我们称之为泥石流沟。泥石流沟的确定是泥石流预测预报的基础性工作之一。
Other Abstract In the construction of the mountainous region, the debris flow gullies which have ceased for several ten or hundred years often regarded as non-debris-flow gullies. After the project completion, the debris flows broke out and would bring about a great loss. Therefore the correct differentiation of debris flow gully is quite importent in the production and construction.Through the practice of late years, author gained the indications distinguishing debris flow gullies according to the analysis of differentiation factors. They may be sorted into direct and indirect factors.The direct factors are. climate and hydrology ( regional annual rainfall, regional anual mean temperature and water sources broken out suddenly), the drainage geomorphologic characteristics ( drainage area, above sea level, difference of height, gradient of gully bed and slope), geology and earthquake ( geoglogic structure and stratum character, earthquake magnitude and season, deposition of the loose solid materials and harmful phsical geologic phenomenon), the accumulational characteristics of debris flow ( viscous debris flow with high density, microviscous debris flow or water-debris-flow )The indirect factors are., water loss and soil erosion (caused by the vegelation damage for artificial and natural factors), and human activity (building road, mining and discarding earth and rock, constructing the winding mountain channel and bombarding the slope )In addition, analysing the data of social investigation, the history and condition of disasters of local debris flows can be traced. This paper stressed the importence of accumulational characteristics of debris flow in differentiation of debris flow gully.
