Based on the practical implementation of initial water rights allocation in Dalinghe River Basin, the initial water rights allocation research progress was summarized from four aspects, such as allocation scopes, allocation mechanisms, allocation principles and allocation models. Combined with the characteristics of Dalinghe River Basin and the index system of water resources allocation in China, a new evaluation index system of water rights allocation is designed from four dimensions, including the fairness, efficiency, sustainable development, and macroeconomic regulation & control. The effectiveness of initial water rights allocation is evaluated comprehensively in Dalinghe River Basin based on the coupling models of Delphi method, Topsis method, and Coordination degree evaluation method. The evaluation results show that under the action of macroeconomic regulation and the control of both the central government and water administration department in Dalinghe River Basin, water rights allocation in Dalinghe River Basin is matched with its social and economic development. In addition, the coupling coordinated development validity reaches a higher level by strengthening democratically political consultation among different provinces and cities in Dalinghe River Basin. The effectiveness of the method is verified by the case analysis.
