Abstract： Regional integration is a crucial driving force for regional economic development. Based on the land use and socioeconomic data， this study adopted methods including equivalent factor correction and Pearson correlation analysis， and employed the coupled GMOP-PLUS-InVEST model to conduct quantitative assessment and multi-scenario simulation of land use changes and ecosystem services （ESs） （water yield， carbon storage， habitat quality and soil conservation） in the Xi'an and Xianyang area from 1985 to 2030. In addition， the trade-off and synergy relationships among different ecosystem services were explored. The results showed that： During the study period， the main land use change was a continuous decrease in cropland， which was mainly converted into forest land， grassland and construction land. Carbon storage and habitat quality exhibited a decreasing trend， while water yield showed a trend of decreasing first and then increasing. Ecosystem services in the Xi'an and Xianyang area were dominated by synergistic relationships， among which the pairs of water yield-carbon storage and water yield-habitat quality shifted to trade-off relationships in 2010. The comprehensive development scenario can effectively balance the expansion of construction land and ecological protection， which is more conducive to the green and sustainable development of the Xi'an and Xianyang area.

Key words： regional integration; land use; ecosystem services; multi-model coupling; trade-off and synergy; Xi'an and Xianyang Region
