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87．36×104 m3,近期可能参与近期泥石流活动量约7．9×104 m3。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。

화평구위일로니석류구,역사상다차폭발니석류。해구류역면적15．90 km2,주구장7．4 km,주구평균종비강208‰,송산고체물원총량위87．36×104 m3,근기가능삼여근기니석류활동량약7．9×104 m3。재유리적자연지질배경조건화인위인소상호작용하형성니석류재해。
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 × 104 m3 , recently may be involved in the recent debris flow activity is about 7. 9 × 104 m3. The inter-action of natural geological environment conditions and human factors were induced the formation of debris flows disasters.
