Simulating the flows of ecosystem services (ESs) can help understand their spatiotemporal flow paths from generation to use, thereby facilitating payments from beneficiaries to providers of ESs. In this study, an analytical framework incorporated with ES flows and regional disparity was established to compute payments for wind erosion prevention service (WEPS). The results showed that between 2010 and 2015, both the potential and actual wind erosion amounts in Yanchi County decreased considerably, and the total amount of sand fixed by WEPS decreased significantly from 3.71 x 10(9) kg to 0.08 x 10(9) kg; additionally, the economic value of the WEPS also decreased from CNY 479.46 million to CNY 10.22 million. Based on the spatiotemporal movements of the physical and economic value flows of the WEPS, this study revealed spatiotemporal relationships between areas providing and benefiting from the WEPS of Yanchi County and provided a direct, scientific basis for decision makers to formulate payment systems for WEPS. The total amount paid for WEPS by beneficiaries in China should theoretically be CNY 38.16 million in 2010 and CNY 1.00 million in 2015 based on the economic value flow of WEPS and the regional disparity coefficient. This framework can provide a scientific and objective basis for establishing horizontal ecological compensation policies. (C) 2019 Published by Elsevier B.V.
