For the northern farmingpastoral zone characterized by salinization effects and wind and sand activities, studying the spatial differences in ecosystem service functions and their rheological mechanisms can help to clarify the spatial relationship between service provision area (SPA) and service benefit area (SBA) and crossregional ecological compensation schemes. The hybrid singleparticle Lagrangian integrated trajectory (HYSPLIT) model and the potential source contribution function model (PSCF) were used to simulate the impact of the sandstabilization ecosystem service (SSS) of the largescale salinealkali sand source area (dry salinealkali lake in Angulinao) ecosystem on wind erosion and SBA. The radiation benefits in terms of land cover, population and gross domestic product (GDP) were determined, and crossregional horizontal ecological compensation schemes were proposed based on the results of the radiation benefits. The results showed that the SSS of ecosystem in the study area was significant, and the amount of sand fixation reached 3679.3 million tons; the transmission path of SSS extended to the east, mainly affecting North China and Northeast China. The land area of SBA was 1893.7 million km2, accounting for 19.66% of the total area of China. The benefit scope included 15 provinces (cities and districts) such as Beijing, which was 41.167 times of the research area itself; the beneficiary population reached 527 million people, and the total benefited GDP was 28.37 trillion yuan; the ecological restoration of salinealkali land in the study area reduced the amount of dust in the beneficiary areas by 1471.700 t, and the direct economic benefit reached 4426 billion yuan. The ecological compensation fund was jointly undertaken by 15 beneficiary provinces (cities and districts). Heilongjiang Province and Inner Mongolia Autonomous Region had the largest compensation amounts. Followed by Hebei Province, Jilin Province, Liaoning Province and other provinces, Zhejiang Province had to pay the least amount of ecological compensation. Based on the theory of ecosystem service flow, the SSS provisiontransmissionbenefit mechanism was analyzed, the quantitative relationship between SPA and SBA was studied, and the actual beneficiaries and benefits were determined. Through the application in dry salinealkali lake in Zhangbei County, Hebei Province, this work can provide policy makers with a reference to promote ecological construction through horizontal ecological compensation and reduce the damage caused by soil wind erosion.
