Abstract:

The pattern and quality of ecosystems would change due to the coupling effects of natural and human activities, and their changes would directly affect ecosystem services and human well-being. Located in the central region of Inner Mongolia, Xilingol League is an important ecological security barrier for the Beijing-Tianjin-Hebei region and is also a major source of livestock products. It is of great significance to study the evolution and driving factors of the ecological pattern of the Xilingol League to build an ecological security barrier in northern Inner Mongolia. In this study, the remote sensing image was used to analyze the changes in ecosystem types and quality of 2000 and 2015 and analyzed the effects of multiple factors included resource development, urbanization development, and policy implementation on the evolution of the ecosystem in Xilingol League. Results showed that the overall quality of the ecosystem in the Xilingol League was improved in 2000-2015, and the quality of grassland ecosystems improved most in the middle and eastern regions. The area of grasslands, shrubs, towns, bare land, wetlands, forests, and mining areas showed an increasing trend, but the area of farmland, sand, and water showed a decreasing trend. The pattern and quality of the ecosystem in the Xilingol League were affected by the interaction of human and natural factors, which had a positive relationship with precipitation while correlated negatively with temperature. There was a positive correlation between the GDP and mining area ecosystem, and the policy of returning farmland to grassland had prompted the transfer of farmland to grassland.

Key words: Xilingol League, ecosystem pattern, ecosystem quality, driving factor
