Abstract:

Land expansion is facing problems, such as extensive utilization of resources, destruction of ecological environments, and imbalanced regional development. Clarifying the adaptation of the land’s functions is conducive to regional coordinated development. The main contents include evaluating the adaptation of the land’s functions in the Hohhot-Baotou-Erdos region in 1990, 2000, 2010, and 2018, and analyzing its temporal and spatial adaptation characteristics. This paper evaluates the synergy/trade-off relationship of the adaptation of the land’s functions based on the coupled coordination model and the bivariate spatial autocorrelation model. The main conclusions are as follows: first, the land functions in the region of Hohhot-Baotou-Erdos have significant temporal and spatial differentiation characteristics, the production/living functions rise locally, and the spatial distribution takes each municipal district as the high-value center circle/semi-circle distribution pattern with a decreasing outward gradient; second, the overall trend of the ecological function is continuously downward and its spatial agglomeration has the scale-dependent effect of a natural landscape; third, the synergy trade-off relationship of the spatial-temporal differentiation characteristics of the land’s functions are obvious. The coupling coordination degree of land and spatial functions of each flag county has been on the rise from the time sequence adaptation characteristics, and the number of flag counties increases; however, the overall level is low; fourth, the synergy/trade-off relationship of various functions in land space has obvious spatial differentiation characteristics, and this relationship alternately changes with time. The spatial distribution and agglomeration effect of the synergy/trade-off relationship of production and living functions is significant, and the spatial distribution of the this relationship between production/living ecological functions tends to be discrete. Ultimately, the spatial coupling effect of the synergy/trade-off relationship between various functions is at a low level as a whole.
