Ecological shelter construction is an important means to promote the Chinese-style modernization of harmonious coexis-tence between man and nature,and the evaluation of ecological shelter construction in inland river basin is of great significance for sum-marizing the effectiveness and problems of ecological shelter construction and implementing the strategic task of Chinese-style modern-ization construction.Based on the social-ecological coupling perspective and the construction of ecological shelter construction evalua-tion index system,this paper made a dynamic comprehensive evaluation of ecological barrier construction in Hexi inland river basin u-sing the comprehensive index method,and put forward the enhancement strategy accordingly.The results showed that:①From 2015 to 2020,the comprehensive index of ecological shelter construction in Hexi inland river basin showed a slight upward trend,the ecological shelter construction was in the stage of development and enhancement,and the ecological security of the basin was mostly in a general or poor state.②The overall spatial effectiveness of ecological shelter construction showed a gradually decreasing trend from west to east,in which the effectiveness of ecological shelter construction in Zhangye City was evident,the comprehensive index of ecological shelter con-struction steadily increased.On the above,this paper suggested integrating ecological shelter construction into the whole process of basin construction from the perspective of the integrity of the social-ecological system,making overall planning and systematic arrangements in terms of eco-industry,eco-culture and eco-society,and coordinating the transformation and improvement of basin ecological shel-ter construction.
