流域泥石流防治效益评估模型初探

Preliminary Study on Evaluation Model of Valley Debris Flow Control Benefit

该文对流域泥石流防治效益的评估方法作了系统的探讨。首先从影响防治效益的诸多因素中筛选出主要因素，建立了具有层次结构的评估指标体系，并给出了有关指标的计算方法，最后讨论了用模糊综合评判方法对防治效益进行评估的方法和步骤。该文所提出的评估方法客观性强，简便易行，便于在实际中推广应用。

An evaluation method on valley debris flow control benefit is proposed in this paper.First,a hierarchy system for evaluation is established by selecting main factors,then the computingmethods of index are presented.Finally,a comprehensive evaluation method of fuzzy mathematicsis used.The method proposed by this paper is more objective and easy to be realized in application.
