摘要
根据坝系规划评价的原则和层次分析法,选取了3个层次、9个指标的坝系规划评价指标体系。通过分析研究得出坝系规划评价指标体系各指标的计算方法,并确定了各指标的权重值,最终计算出小流域坝系规划综合指数。计算结果显示,小流域坝系规划综合指数越大,经济、社会、生态3大效益也越大,因此在小流域坝系多方案规划中选择综合指数最大的作为优化方案。该方法值得推广使用。
According to the evaluation principle of dam system planning and the analytical hierarchy process（AHP）,three hierarchies and nine indicators are selected as an evaluation system of dam system planning.Calculation method for each index in the evaluation system of dam system planning is obtained by analyses,weighted value of each index is determined,and finally a comprehensive index of dam system in small watershed is calculated.The computational results show that the greater the comprehensive index in small watershed,the better the economic,social and ecological benefits are.Therefore,the greatest comprehensive index may be selected as the best solution in the schemes for dam system planning in small watershed.The approach can be recommended for practical uses.
