Abstract:

Objectively understanding the ecosystem services of the Mongolian Plateau and their response to climate factors is of great significance for formulating scientific strategies for ecosystem protection and utilization under the climate change. Based on the data of land use/cover and meteorological observation, this study combined model simulation, spatial analysis and statistical analysis to explore the spatiotemporal patterns of main ecosystem services and theirs relationships with climate factors in the Mongolian Plateau. The results showed that: (1) The habitat quality, water production, carbon storage, and green leisure services of the Mongolian Plateau were high in the east and low in the west, high in the north and low in the south. The air purification service was high in the west and low in the east, high in the middle and low in the surrounding areas. (2) From 2000 to 2020, habitat quality, water yield, carbon storage and green leisure services showed increasing trends with the increase rate of 9.76%, 36.02%, 7.96% and 7.37%, respectively, and the variation of ecosystem services showed an obvious spatial heterogeneity. (3) Climate factors including annual average precipitation, temperature and wind speed are significantly correlated with different ecosystem services. For the whole region of Mongolian Plateau, precipitation contributed most to changes of habitat quality, water yield, carbon storage and green space leisure; wind speed contributed most to the changes of air purification. The contribution of various factors also varied in different subregions. The study comprehensively evaluated the ecosystem status of Mongolian Plateau from the perspective of ecosystem services. The findings could provide scientific reference for China-Mongolia cooperation in ecosystem management to adapt the climate change.
