基于能量概念的泥石流减灾新思路

陆地上发生的很多变迁都是受能量流控制的，特别是在泥石流这种具有复杂性、突发性、群发性、继承性和局部性等特征的山地灾害过程中，能量趋于均衡化是它们发生和输移的根源和驱动力。本文从能量的角庞出发，通过阐述能量线性模型的原理，分析泥石流输移时的各种能量消耗，从宏观角度提出了减轻泥石流灾害的一种新的思路，即可以从控制能量或熵消耗的角度出发，通过减少固体物质来源量和增大摩擦两种途径来采取一系列减灾措施，为制定泥石流防治规划提供参考。

A new viewpoint of debris flow disaster mitigation based on energy conception

The energy flow controls many transitions that happen on the land, especially in process of debris flow, the energy attenuation is the reason and driving force. This paper base on energy, according to represent the axiom and application of energy-line model, explain the calculation formula of energy consumption, introduce a new viewpoint of debris flow mitigation. The new concept is that we can start with controlling energy decay, through reducing the moving mass and enhance the external and internal friction, adopt a series of measures to provide reference for preventing and curing the influence of Debris flow.
