Service Value and Influence Factors Analysis of Farmland Meta-ecosystem in Land Desertification Control Areas -A Case Study of Eight County in Hexi Corridor
[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.
