- Abstract:
- In order to reveal the distribution pattern and its spatiotemporal change of ecosystem services supply and demand in the Loess Plateau in northern Shaanxi Province，the ecosystem service supply and demand of the study area was quantitatively assessed and mapped via the land use and related geographical data from 2000 to 2015，the ecosystem services supply and demand integrated index was constructed，and the change pattern of the ecosystem service supply and demand was analyzed. The results show that:(1)the quantities of various supply services in the study area have increased，while the whole ecosystem service supply pattern was not changed obviously; from 2000 to 2015，the increase of supply services was obvious(22.05%)，and the increase of regulation services was small(2.41%); during the study period，the ecosystem service supply maintained a pattern of high value in the north，median value in the middle，lower value in the middle and eastern part，and the lowest value in the mid-north;(2)the demand for ecosystem services has increased year by year，but the total supply pattern of ecosystem services was no obvious change; the largest increase was the total GDP(20.93)，and the smallest was the total population(1.17); during the study period，the demand for ecosystem services generally maintained a pattern of lowest and lower demand in the south and mid-east，medium and higher demand in the central and western regions，and highest demand in the north;(3)comprehensively considering the overall characteristics of the supply and demand of ecosystem services in the study area，four types of ecosystem service supply and demand and four change modes were formed. In conclusion，the supply and demand of ecosystem services increased finally with little change of the spatial pattern in the Loess Plateau in northern Shaanxi Province from 2000 to 2015.
