Abstract: Taking the Beijing-Tianjin-Hebei region as the sample, the ecological, social and economic data of the Beijing-Tianjin-Hebei region from 2004 to 2018 were selected, the index weight system of desertification control was established, and the coupling degree, coupling coordination degree and entropy method were introduced to measure the coordination status of the coupling system. The results showed that from 2004 to 2018, the comprehensive development index of the Beijing-Tianjin-Hebei region had been in a state of continuous growth, and the coupling coordination degree was in a fluctuation and rising trend. The coupling coordination of Beijing and Hebei was always in the high quality coordinated development category; Tianjin had experienced moderate depression to severe depression to moderate depression, which was lower compared with Beijing and Hebei. There was some volatility in the integration process of the Beijing-Tianjin-Hebei region, and the comprehensive integration development of the Beijing-Tianjin-Hebei region was slower than the integrated development of economic, social and ecological subsystems.

Key words: desertification control, ecological, social and economic integration, coordination mechanism, Beijing-Tianjin-Hebei region
