根据水利投资项目具有内部结构复杂，涉及因素众多，影响范围广泛，后果影响重大、深远，且难以预测等特点，以尼尔基水利枢纽工程为例，提出了一种较为完善的、对水利工程具有普遍意义的综合评价指标体系。采用Delphi法与层次分析法相结合的方法求出各指标权重值，并采用多层次模糊综合评价模型对其进行评价，得出了比较全面、客观的结论。

A water conservancy investment project is characterized by: a complicated inner structure, much factors involved in it, a wide influence range, and profound effect and consequent hard to forecast. Taking the Nierji Hydraulic Project as an illustration, this artical puts forward a relatively perfect synthetic assessment index system of the water conserancy inuestment project, calculates each index weight by using the Delphi method and AHP method, evaluates the project by employing the fuzzy analytic hierarchy integrated assessment methed, and then gets a relatively overall and objective conclusion. 
