Abstract Based on the study of natural environment, geography and natural resources, the comprehensive regionalization of natural resources is conducive to fully understanding and analyzing the internal natural resources environment status and its dynamic change, which could also provide some decision-making basis for the investigation and supervision of natural resources, the sustainable development and planning of regional economy. In this paper, the authors have adopted the environmental geographical elements and natural resources as the basis to divide different regions and carry out the comprehensive regionalization. The scientific understanding of regional differences and the dynamic change of natural resources could be strengthened through the comprehensive regionalization, which has important guiding significance for the rational development and utilization of natural resources. Through difining the dominant division and auxiliary decision-making elements of the regionalization units, the authors have used the principal component analysis and cluster analysis method to preliminarily divide the comprehensive regionalization of natural resources into three level system. The secondary regionalization includes seven natural resources subregions, while the tertiary regionalization includes 14 natural resources districts. Besides, the temporal and spatial dynamic characteristics for natural resources from 1990 to 2018 at all levels were also quantitatively analyzed. The results show that the overall change of the dominant resources is the decrease of forest resources and the significant increase of cultivated land resources. The specific changes is the transformation from forest to cultivated land and the transformation from grassland to cultivated land.
