Evaluation model of regional resource and environment comprehensive carrying capacity based on the conjugation-wrestling mechanism

Abstract

The resource and environment carrying capacity is the basis for strategy decision-making of regional development, especially the optimization of spatial development strategy. In recent years, it has played a pivotal role in guiding regional sustainable development, land planning, urbanization, post-disaster reconstruction planning, and industrial planning. At the same time, clarifying the interaction mechanism between regional resource-environment and production-living factors is the basis of the evaluation of resource and environment carrying capacity. Based on PSR model, this paper presents the conjugation-wrestling theoretical mechanism of resources-environment and production-living, which divides the carrying capacity into four pairs of interaction forces, i.e., support-sensitive point, recovery-fragile point, destruction-critical point and development-equilibrium point. Then it presents DENS model including four dimensions, namely development, environment and disaster, natural resource and ecology, and social welfare.
