Abstract:
According to the “exposure-sensitivity-adaptive ability” criterion of vulnerability assessment, the entropy weight method, weighted summation model and spatial regression model are used to explore temporal and spatial differentiation and influencing factors of vulnerability for urban “social-economic” system in the Loess Plateau from 2005 to 2015.The results show that the urban “social-economic” system in the Loess Plateau is moderately fragile and in a benign orbit. The vulnerabilities of the “social-economic” systems of different types of cities show different evolutionary characteristics. The vulnerability of resource-based cities and most urban agglomerations declines. The provincial capitals face strong risk coercion due to the polarization effect. The vulnerability index in the Loess Plateau has gradually increased from east to west. The large topographic unit as an important part of the natural environment has great significant impact on vulnerability differentiation. The hotspots region has always been concentrated in the Gully area of Loess Plateau in the eastern part of Qinghai Province. From the perspective of vulnerability dimension assessment, it is clearly indicated that the core issue of urban development in the Loess Plateau has been transformed from promoting economic growth to improving sustainability, that is, the construction of both software and hardware infrastructure, improving economic efficiency, regulating urban-rural imbalances, and reducing resource and environmental pressures for economic development.
