摘要
川西地区受其独特的地形地貌、气候特征、区域性地质构造及强烈的地壳抬升影响，泥石流极其发育，为我国泥石流极活跃的区域。研究表明，川西泥石流的发育特征具有成带性、周期性、季节性和夜发性特点。文中还对川西泥石流危险程度进行划分，为环境保护、减灾防灾提供了依据。
Affected by the topography, landform, climate, geologic structure amd crustal uplift of Western Sichuan,the debris flow is very active.The study in this paper indicates that the debris flow takes on properties of zone, period, season and night occurrence. And its debris flows dangerous degree distribution proves the fundament for environment protection and disaster decrease.
