Abstract:

The agropastoral ecotone is an important ecological security barrier and grain producing area in northern China. Elucidating the spatial evolution law and influencing factors of production-living-ecology spaces in the ecologically fragile areas for land space optimization and sustainable development is extremely important. In this study, the methods of land use dynamic degree, land transfer matrix, and geographical detector were used to explore the spatial evolution characteristics and influencing factors of production-living-ecological spaces in Hohhot, a typical farming-pastoral ecotone in Inner Mongolia, from 2000 to 2020. The results show that during the study period, the overall dynamic changes in the production-living-ecological space of Hohhot were gentle (0.02%-0.04%). The spaces for ecology, agricultural production, and animal husbandry decreased, while the spaces for life and other production increased. From 2000 to 2020, the spatial patterns for production-living-ecological in Hohhot changed significantly, and this was mainly manifested in the occupation of agricultural and animal husbandry production spaces by the living space outside the urban area, and the mutual transformation of agricultural production, animal husbandry, and ecological spaces in the Tumochuan Plain and its northern and southeastern hilly areas. During the study period, the mutual transformation of ecological, agricultural, and livestock production spaces was intense, but this decreased after 2010. Living spaces and other production spaces were in a state of net inflow, especially in the latter decades. The average slope is the dominant factor affecting the spatial layout of agricultural and animal husbandry production (0.24-0.4). Industrial development, human activities and agricultural production scales have a greater impact on the local spatial patterns. Based on refined governance, the role of policy guidance is increasingly prominent.
