Ecological security of mineral resource-based cities in China: Multidimensional measurements, spatiotemporal evolution, and comparisons of classifications

Accurate assessments of the ecological security of mineral resource-based cities in China (MRBCCs) are one of the most important elements of improving comprehensive national security policies in the country and promoting high-quality development therein. To this end, an integrated method is proposed...

description	Accurate assessments of the ecological security of mineral resource-based cities in China (MRBCCs) are one of the most important elements of improving comprehensive national security policies in the country and promoting high-quality development therein. To this end, an integrated method is proposed herein based on rough set-entropy weight method-spatial data analysis, and an ecological security assessment indicator system is constructed based on a pressure sensitivity–stability–external regulation nexus. The ecological security status of 108 MRBCCs was evaluated in multiple dimensions and based on their spatiotemporal evolution. The results show that the comprehensive ecological security of MRBCCs improved from 2010 to 2018, but it was still low. There exists strong heterogeneity in the comprehensive ecological security of different cities, and the gap will only increase over time. Additionally, the comprehensive ecological security of MRBCCs dependent on coal, petroleum, non-ferrous metal, and ferrous metal showed an upward trend from 2010 to 2018.
