Abstract:

Mountainous areas are complex in land distribution, and are also important ecological barriers and ecologically fragile areas. The spatial pattern and dynamic changes of land use in mountainous areas will affect the development of ecological functions in mountainous areas. Exploring the spatial heterogeneity of mountain land and its corresponding ecological effects is the key for mountain regions sustainable development. Based on the three typical mountain areas (Taihang Mountain, Hengduan Mountain and Karst Mountain regions), we clarified the land use spatial heterogeneous characteristics in vertical and horizontal directions, and evaluated the water yield, soil retention, carbon storage and habitat quality. Finally, we took the total mountainous areas in China to analyze the vegetation change trend and its influencing factors in recent 30 years.

Key words: mountain region, land use, resource and ecological effect, ecosystem service
