摘　　要：韭园沟流域坝系工程安全评价方法研究是在调查、分析研究的基础上,确定坝系安全评价指标和指标标准,应用层次分析法建立了坝系工程安全评价方法。通过计算流域骨干坝安全度均大于0.8,骨干坝布局均衡系数0.9,坝系安全度0.892 62,从计算结果看,韭园沟流域坝系基本处于安全状态,骨干坝布局比较合理,评价结果基本上与实际相符。因此,认为这一评价指标体系和评价方法可以在黄土高原小流域坝系安全评价中推广应用。Based on the investigation and analysis, the research method is carried out, and the salty evaluation index and its evaluating criteria for the dam system project are determined. Using the Analytic Hierarchy process, the safty evaluation method of dam system project is established. Through calculation, the safty degree of the key dams is higher than 0.8, the coefficient of layout equilibrium is 0. 9, safety degree of dam system is 0. 89262. The results indicate that the dam system in Jiuyuangou is salty, layout of key dams is reasonable, and the evaluation resuits basically accords with the actual situation. Accordingly, this evaluation index system and evaluation method can be applied to small watershed in loess plateau .
