Change characteristics and formation mechanism of the territorial spatial pattern in the Yellow River Basin from 1980 to 2018,China

Scientifically recognizing the change process and influencing factors of the territorial spatial pattern in the Yellow River Basin is an urgent need to build a sustainable territorial spatial development and protection pattern and achieve high-quality development in this area. Based on the methods of territorial spatial transfer matrix, standard deviational ellipse and geographical detector, this paper studies the change characteristics and the formation mechanism of the territorial spatial pattern of the Yellow River Basin from 1980 to 2018. The results show that: (1) In the past 40 years, the territorial space of the study area features obvious horizontal regional differences and vertical gradient differentiations; with the continuing decrease of production space and expansion of living space, the ecological space has occupied the absolute dominant position, but with a fluctuating trend. (2) The changes in the territorial spatial pattern of the basin have gradually accelerated, and regional differences and spatial orientations have become more prominent. There is spatial synergy between the areas with reduced agricultural production space and the areas with increased forest land, grassland and other ecological space. (3) The influence of annual average temperature on production space has significantly improved, and the restraining effect of altitude on living space and ecological space has gradually strengthened; the population density and the investment scale of fixed assets have wide impact on the evolution of production and living space pattern, and the urbanization rate and ecological environment protection policies have profound impact on the evolution of ecological space. (4) The natural backgrounds of the Yellow River Basin are important geographical bases for the formation of current territorial spatial development and protection pattern; the urbanization, the industrialization and the ecological protection and construction policies are the key driving forces for the change of territorial spatial patterns, which have accelerated the change process of territorial spatial pattern in the basin; the interaction of natural and human factors has significant non-linear enhancement effect and bi-factor enhancement effect on the evolution of the territorial spatial pattern.
