中文摘要：

在遵循有效性、公平性和可持续性原则构建初始水权分配指标体系的基础上,针对初始水权分配中指标体系存在显著的相关性和权重偏好非一致性等问题,提出将主成分分析应用于初始水权分配中以消除相关性的影响。该方法先用主成分分析法对指标体系进行赋权,之后结合改进AHP与熵权法对多层次指标体系进行组合赋权,以消除单一权重方法的片面性,并利用博弈论进行指标权重的综合集成,最后运用综合评价法确定初始水权进行分配权重。将此方法用于湖北省应城市的初始水权分配,结果分析表明,采用该方法进行初始水权分配可行且合理。该方法可以为其他区域的初始水权分配提供参考和借鉴,并为水资源的统一管理奠定了基础。

英文摘要：

The index system of the initial water rights allocation was constructed following the principle of effectiveness,equity and sustainability.Aiming at the problems of significant correlation of index system and inconsistency of weight preference of initial water rights allocation,Principle Component Analysis（PCA）was applied to the initial water rights allocation to eliminate the impact of correlation.In the method,firstly,Principle Component Analysis（PCA）was proposed to empower the index system,Thereafter,improved AHP and entropy method were adopted to determine weights for multi-lever index system,which eliminated the unilateral result.And game theory was used to carry out the comprehensive integration of index weight.Finally,a comprehensive evaluation method was used to allocate initial water rights.The method was applied to study the initial water rights allocation in Yingcheng,Hubei province.The verification of the model and the analysis of the experimental results showed that the proposed method worked well and was rational and practical.The model could provide a reference for initial water rights allocation in other areas and lay the foundation for the unity management of the water resources.
