摘要
矿业城市的综合承载力变化是一个复杂的多因素协同促进的结果,厘清矿业城市承载力内部的耦合协调特征对于促进城市转型发展具有重要意义.以往研究多从整体视角度量承载力变化,但对其内部组成的相互作用机理探究较少.因此本文构建了一个针对矿业城市资源-环境-发展承载力的耦合评价指标体系,试图通过TOPSIS模型分析2012到2020年鲁南矿业城市子系统承载力的耦合协调特征.结果表明:(1)2012—2020年鲁南矿业城市综合承载力水平都呈稳步上升趋势,但大气排放状况与资源存量的数值变化会对综合承载力产生波动影响,成熟型矿业城市济宁的承载力高,提升速度更快;(2)三个子系统中,资源承载力与环境承载力相关性较高;(3)鲁南矿业城市的资源-环境-发展承载力都已从失调水平提升到协调水平;(4)耦合协调度提升过程中充满波折与挑战,特别是在发展初期资源枯竭和环境下降的双重影响下.研究为该地区矿业城市的产业转型升级和可持续发展提供借鉴,也可为类似资源型城市在资源开发和环境保护中寻找平衡点提供科学依据.
The change of the comprehensive carrying capacity of mining cities is the result of complex multi-factor coordination.It is of great significance to clarify the coupling and coordination characteristics of the carrying capacity of mining cities to promote the urban transformation and development.Most of the previous studies measured the variation of carrying capacity from the perspective of the whole,but the interaction mechanism of its internal components was rarely explored.This paper constructed a coupling evaluation index system for resource-environment-development carrying capacity of mining cities,and attempted to analyze the coupling coordination characteristics of carrying capacity of various parts of mining city in southern Shandong province from 2012 to 2020 through TOPSIS model.The results showed that:(1)From 2012 to 2020,the comprehensive carrying capacity of mining cities in southern Shandong province showed a steady upward trend,but the numerical changes of atmospheric emissions and resource stocks would have a fluctuating effect on the comprehensive carrying capacity.Jining,a mature mining city,had a high carrying capacity and a faster rate of improvement;(2)Among the three subsystems,the correlation between resource carrying capacity and environmental carrying capacity was relatively high.(3)The resource-environment-development carrying capacity of the mining cities had been improved from the imbalance level to the coordination level;(4)The process of improving the coupling coordination degree was full of twists and turns and challenges,especially under the dual influence of resource depletion and environmental decline in the early stage of development.The research provided reference for the industrial transformation and upgrading and sustainable development of mining cities in this region,and also provided a scientific basis for similar resource-based cities to find a balance between resource development and environmental protection.
