[Objective] To assess the benefits of comprehensive management and provide support for government policy making. [Methods] The concept of DPSIR model was introduced into the eco-environment benefit evaluation index system. AHP-entropy and TOPSIS method was used to evaluate the eco-environment benefit of the comprehensive management in ten tributaries in Inner Mongolia section of the Yellow River. [Results] Value of the integrated management in ten tributaries from highest to lowest was: Hantaichuang > Xiliugou > Hashilachuang > Husitaihe > Maobula > Muhaerhe > Dongliugou > Boergasetaigou > Heilaigou > Haoqinghe. The comprehensive effect index was high in the middle, but low in both sides. Hantaichuan was class Ⅱ, while the other tributaries was class Ⅳ, and the comprehensive management in this region was poor. [Conclusion] The internal structure of the DPSIR-TOPSIS model was clear, and it well explained the intrinsic link between watershed comprehensive management engineering and environment-economy-society system. This study provides a new method for assessing the eco-environment benefit of comprehensive management.
