The present paper express the terrain character index in drainage – system with the shape of the longitudinal profile of the debris flows,and studied the stability and evolution of the debris flows by the "Superentropy" theory with the fuzzy comprehensive evaluation method to evaluate the debris flow hazard.
本文以研究项目为依托,选择泥石流流域沟谷的纵剖面形态指数作为流域的地貌特征指标,用超熵理论量化泥石流流域地貌系统的稳定性与演化趋势,并借助于模糊综合评判手段,对泥石流危险性进行评价。
