Abstract: Taking Yanshan-Taihang Mountains Area as the study area, the ecosystem service value (ESV) was calculated based on the ESV evaluation model. And the dynamic change process of ESV was systematically analyzed. Meanwhile, the spatial evolution of ESV trade-offs/synergies was compared at different spatial scales (county, town and grid). The results show that: (1) In the study area, the ESV increased continuously from 2 985.09×108 yuan in 2000 to 3 171.01×108 yuan in 2019. The spatial distribution of ESV was high in the east and north, and low in the west and south. (2) Among all kinds of ESV, the regulation service was the highest, followed by support, supply, and cultural services. Among all kinds of land use, the ESV of forest was the highest, followed by the ESV of grassland, cultivated land, wetland, water system and desert. (3) Synergies were the dominant relationships between ecosystem services, and tradeoffs only existed between supplying service and the other three services in the study area. The tradeoffs/synergies were different at different space scales (county, town, and grid). The synergies were dominant at county scale, while the tradeoffs/synergies co-existed at town and grid scales. The results are of great significance for accurately understanding the values and trade-offs/synergies of ecosystem services at different scales. It can provide scientific references for ecosystem protection and restoration in the concentrated poor areas of Yanshan-Taihang Mountains, and also lay a foundation for achieving the win-win situation of economic development and ecological protection in poverty areas.
