摘要:

客观理解蒙古高原生态系统服务及其对气候因子的响应对于气候变化背景下制定科学的生态系统保护和利用策略具有重要意义。基于土地利用/覆盖和气象观测等数据,综合运用模型模拟、空间分析和统计分析等方法,探究蒙古高原主要生态系统服务的时空格局及其与气候因子的关系。结果表明:(1) 蒙古高原生态系统生境质量、产水量、碳储量、绿地休闲服务均呈现出东高西低、北高南低的分布格局,空气净化服务呈现西高东低、中部高四周低的空间分布格局。(2) 2000—2020年,除空气净化服务总体呈降低趋势外,生境质量、产水量、碳储量、绿地休闲服务表现出不同程度的增加趋势,增长率分别为9.76%、36.02%、7.96%、7.37%,各类生态系统服务的变化幅度具有明显的空间异质性。(3) 年均降水量、温度和风速等气候因子与不同生态系统服务均呈现出显著相关性,总体上来看,降水量对生境质量、产水量、碳储量、绿地休闲等服务变化的影响贡献最大,风速对空气净化服务变化产生的贡献最大;不同亚区内,各类因子的贡献也存在一定差异。研究从生态系统服务的角度较全面地评估了蒙古高原生态系统状况,结果能够为中蒙合作开展适应气候变化的生态系统管理提供科学参考。

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.
