[Objective] It is necessary to study farmland meta-ecosystem service value to reflect the region ecosystem safe and farmer livelihood sustainable in arid area.[Methods]This paper calculated farmland meta-ecosystem value and analyzed the influence factors of eight county protection of desertification land perimeter of Hexi Corridor in the arid region by ecological economic method and multiple regression.[Results] The result showed that farmland meta-ecosystem unit area service value increased from 19 966 yuan/hm² to 21 511 yuan/hm², the increment was 1 545 yuan/hm², the annual average growth was 0.58%. Raw material production, waste treatment, soil formation, erosion control and food production were the main increased items. Farmland meta-ecosystem total value increased from 2.94×10⁹ yuan to 4.25×10⁹ yuan,the increment was 1.31×10⁹ yuan, the annual average growth rate was 2.88%. The quantity of basic service value and social security function value had greater increases than environment pollution service value and water consumption function value had, but the increase rates of environment pollution service value and water consumption function value were faster than those of basic service value and social security function value. The changes of farmland meta-ecosystem unit area service value of the eight countries had spatial and type differences, Except of Dunhuang City, farmland meta-ecosystem total service values of seven countries increased. The variation of farmland meta-ecosystem service value in the study area was mainly affected by grass agriculture production, rural per capital income, chemical fertilizer consumption, scale economic crops and grain yield per hectare.[Conclusion] The Reversion of ecological degradation has positive influence on farmland meta-ecosystem value of most country, but environment pollution and water consumption were increasing constantly, for that reason, the vulnerability of land desertification reverse trend is still high.
