基于共轭角力机制的区域资源环境综合承载力评价模型

厘清区域资源环境与生产生活要素的相互作用机制,探索区域资源环境承载力的内生机制与评价模型,对支撑国土空间规划编制乃至战略实施具有重要理论和实践意义。基于“压力—状态—响应”模型思路,提出区域资源环境与生产生活要素的“共轭角力”理论机制,将资源环境承载力解构为“支撑力—敏感点”“恢复力—脆弱点”“损害力—临界点”“发展力—平衡点”四对相互作用力,并据此提出集开发建设、环境灾害、资源生态及社会福祉四个维度的DENS评价模型,为科学地揭示资源环境承载力的理论特征提供借鉴。

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

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.
