摘　　要：和平沟为一老泥石流沟,历史上多次爆发泥石流。该沟流域面积15.90 km2,主沟长7.4 km,主沟平均纵比降208‰,松散固体物源总量为87.36×104m3,近期可能参与近期泥石流活动量约7.9×104m3。在有利的自然地质环境条件和人为因素相互作用下形成泥石流灾害。Heping ditch is an old debris flows, many times debris flows were occurred in the history. The valley area is 15. 90km2 , the main channel length has 7. 4km, main channel average longitudinal gradient is 208‰, total amount of loose sol-id material source is 87. 36 ＆#215; 104 m3 , recently may be involved in the recent debris flow activity is about 7. 9 ＆#215; 104 m3. The inter-action of natural geological environment conditions and human factors were induced the formation of debris flows disasters.
