摘　　要：泥石流防治工程规划属于一种半结构化的决策问题。可拓决策是根据物元的可拓性 ,采用定性分析与定量计算相结合的方法解决矛盾问题的一种决策技术。本文根据可拓学的基本理论与方法 ,提出了一种首先基于系统物元相容性评判进行方案比选 ;再对初选方案通过系统物元变换进行方案优化设计的可拓决策模式 ,并以成昆铁路大田箐沟泥石流防治方案的优化设计为例说明这种可拓决策技术的应用程式。The disaster mitigation planning of debris flow is a kind of semi-structure decision making problem. Extension decision, based on the theory of extenics and the method of qualitative and quantitative analysis, is a good solution for contradictoriness. A model of extension decision with two gradations is provided in this paper. First, the comparison of schemes, according to the compatibility analysis of system matter element, is carried out. Then, the mitigation planning is treated for optimization by transforming the system matter elements. A case study is carried out on the Datianqing gully using this method.
