In an increasingly meta-coupled world, the balance of interregional environmental development is becoming increasingly important, and an ecological cooperation community is emerging. Mapping the flow of an ecosystem service (ES) can aid in understanding the spatiotemporal transport paths from generation to use, thereby facilitating a visualization of the interregional relationship on environmental management. In this study, we evaluated the material quantity and value of the wind-break and sand-fixing service (WSS) of Inner Mongolia, simulated the material and value flow and identified the service benefitting regions (SBRs). The benefitting land, population and economy in China were used to reflect the WSS flow effect. The results showed that: the total material quantity of WSS in Inner Mongolia was 7.83 × 1012 kg in 2010 and 7.37 × 1012 kg in 2015, with a total value of 7.83 × 1010 CNY and 7.37 × 1010 CNY, respectively, of which 79.18% in 2010 and 79.92% in 2015 flowed to the downwind SBRs out of Inner Mongolia. The spatial transport paths and SBRs were mainly located in northern China, the Korean Peninsula, Japan, Mongolia and the Russian Far East in 2010 and 2015. The material and value flow rate of the WSS had spatial proximity features, resulting in differences in the benefits received by benefitting countries and provinces. The SBRs in China covered 67.50% and 65.67% of the total area of China in 2010 and 2015, respectively. The people benefitting amounted to 88.01% of the total population in China in 2010 and 86.58% in 2015, corresponding to a beneficial gross domestic product (GDP) of 92.00% and 90.50%, respectively, of China's total GDP in each year. Based on the spatiotemporal movements of the material and value flows of the WSS, this study revealed the spatial and temporal correspondences between the area's supply and benefits from the WSS of Inner Mongolia. It provides a scientific basis for decision-makers to coordinate interregional benefit transfers through wind erosion control in Inner Mongolia and ensure continuing flow of benefits to SBRs.
