Abstract

蒋家沟泥石流的发生、发展受控于流域(坡地与沟道)地貌演变过程,并又影响着流域地貌的演变。
蒋家沟泥石流是乌蒙山隆升中遭受强烈切割过程内的必然产物,又是一种外营力、灾害。它随着山坡、谷坡、重力坡系列的演进而发生、发展,又随着这系列演退而逐渐走向消亡或停歇。在这一过程中相应出现散流坡泥石流、滑坡泥石流和崩塌泥石流、随着这些坡面泥石流的发展,便依次促进切沟、冲沟、溪沟等沟道泥石流的发生、发展。流域性泥石流又加速各级沟道与流域地貌的变异性,对干流的影响更趋显著。
在泥石流防治中,需要控制或提高侵蚀基准面,防止沟、坡的恶性发展。这是最基本的原理。其次再据坡面和沟道源地特征采取相应控流、固土措施等。
通过泥石流治理,流域地貌过程势必减慢,坡面和沟道土体趋向稳定,但这种稳定性盐分脆弱,稍有不当,亦可复发泥石流。

 

Other AbstractThe occurrence and development of debfis flow in the Jlangjia Ravine rely on the mountain geomorphic courses and may affect the geomorphic evolution of the mountainous region.The evolution courses of debris flow in the Jiangjia Ravine,slope debris flow and ravine debris flow.The slope debris flow may be expressed as three types i.e. spreading-flow-slope debris flow with the development system of the slopes (slope→valley slope→gravity slope).The ravine debris flow may be expressed as gully debris flow,gully debris flow and brook debris flow with the development system Of gully (cutting gully-gully-brpok). These debris flow evolution may impel the evolution of the basin geomorphy.From the geomorphic view, the principles of prevention and control of debrii flow.control the base level of erosion,restrain the starting conditions of various debris flow origins, enhance the stability of origin earth mass.
