Other Abstract甘洛县泥石流活动十分活跃,曾造成摧毁场镇、冲毁桥梁、颠覆列车、淤埋农田等严重灾害。据现有资料,该县有泥石流沟50条,主要分布在断裂带两侧、背斜轴部和河流峡谷段。预防措施是结合农业改革,恢复森林生态系统和合理开发地下矿藏;治理措施是生物与工程相结合,拦挡与排导相结合进行综合治理。 
;  Ganluo County of Sichuan Province is situated between 102.5°-103. 0°E, 28. 6°-27. 3°N. Debris flow activities are frequent in the county so that the heavy disasters occurred :the towns, villages and small water power stations were destroyed; the railway and highway broke off, and the farmland was silt up.Based on the present data,in this region there are 50 gullies of debris flow,they are 7 largest scales, 13 large, 15 middle and 15 small on scale;they are 21 viscous’ debris flow gullies, 28 transitional and 1 nonviscous debris flow gullies on flow feature.In the county,the debris flow gullies are distributed on both sides of fault zones,anticline axis and river gorges sections. The Niuri River valley in a concentrated belt for faults,anticline and gorges,thus here is dense area of debris flows.The preventing measures against debris flows should reform the agriculture structure,recover forest ecololgic system,raise the environmental quality,weaken hydrodynamic conditions and reduce debris materials, control scale and damage of debris flow.Owing to serious slope destruction,abundant gully deposits, poor conditions for damming debris flows on branch gullies,and limited sand carrying capacity of main river. The preveintion measures combining vegetaion and engineering control, damming and drainge works have been taken in the county.
