摘要:

国土空间面临资源利用粗放、生态环境破坏、区域发展失衡等问题,明晰国土空间功能有利于区域协调发展。以1990年、2000年、2010年、2018年为观测期,在分析呼包鄂地区国土空间功能演变特征的基础上,采用耦合协调度及双变量空间自相关模型对国土空间功能演变的协同/权衡关系进行评价。结果表明:近28 a,研究区生产/生活功能局地上升,空间分布呈现以各市辖区为高值中心、向外梯度递减的圈层/半圈层格局;生态功能有所下降,空间分布具有自然山水规模尺度依赖效应;国土空间功能耦合协调度整体上升,协同关系旗县数量增加,但整体水平较低,空间分异表现为生产-生活功能协同/权衡关系集聚分布;生产/生活-生态功能协同/权衡关系趋于离散;各功能协同/权衡关系空间耦合效应水平较低,国土空间功能亟需调整优化。

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.
