摘要

在对神府-东胜矿区人为泥石流沟道广泛野外调查的基础上

选取了43条典型泥石流样沟。在1∶10000地形图及卫片上进行了形态要素量测

应用流域地貌分析原理

对所有样沟各形态要素进行了详细分析

结果认为

人为泥石流沟道地势比沿程变化特征为

以形成区比降最大

区别于自然泥石流沟道;沟道分区面积比以汇水区面积最大

明显区别于湿润地区;流域形状以扇形为主

沟道给养面积较大

崎岖系数不太大是半干旱地区人为泥石流沟道的独特之处。

Abstract

Shenfu-Dongsheng mine site is located in the passage of arid and semiarid zone. Based on the fragile eco-environment

coalmining and construction have brought out some new environment problems.Man-made debris flow problem is the most serious of them which caused by coalmining

construction of railway and highway as well as exploi ting stone. Because of the particularity of forming process of man-made debris flow

the watershed geomo rphy is very distortion. Throug hevery landform factors of watershed systema tically analyzed

the results show as follows. (1) The gully bed gradient takes conv exshape as the dominant

that is a unique form of man-made debris flow gully. (2) Regional area ratio is the largest in converge water region

and the watershed formation of fan-shaped make up 80 percent of the total sample gul lies

it is favorable to water concentration and a particular demand of motive power of debris flow in semiarid area. (3) The landform rugged coefficient of watershed is not suitable to olarge and the area of providing water for gully formation is larger in semia ridregigon than in moist region.
