Land use function change and its driving force of the "production-living-ecological" space in Fenhe River Basin from 1980 to 2020.

It is of importance to analyze land use function change and driving factors of the production-living-ecological space of national territory to realize the coordinated development. Based on land use remote sensing data in 1980, 1990, 2000, 2010, and 2020, we used the methods of land use dynamics, transfer matrix, center of gravity shift and geographic detector to analyze the pattern of production-living-ecological space in Fenhe River Basin and explore the influencing factors. The results showed that the area proportion of production-living-ecological space in the basin was ecological space > production space > living space from 1980 to 2020. The ecological space and agricultural production land showed a decreasing trend, with a decrease of 72441.19 and 105882.96 hm, respectively. The living space and industrial production land showed an upward trend, with an increase of 119503.02 and 58821.13 hm, respectively. There was significant difference in the land use function change of production-living-ecological space. Agricultural production land had the largest transferred area, accounting for 47.9% of the total. The largest transfer area of industrial land was agricultural land, which accounted for 61.3% of the total from 2000 to 2010. The occupation of agricultural land by urban living land was mainly distributed in the marginal area of various urban areas of Taiyuan Basin. Among them, the increasing area of urban living land in Taiyuan City showed a trend of gradual southward expansion. The center of gravity migration of urban land for living and industrial production land was the most obvious, and that for living showed the trend of first moving south and then moving north, while industrial production land moved northward significantly. The influence of social-economic factors on the land use change was obviously stronger than that of natural factors, while the interaction between social-economic factors had a stronger explanatory power. The results would provide reference for clarifying the relationship between land function transformation and optimizing land use function of production-living-ecological space.
