广东省资源环境承载力评价研究

Study on the Evaluation of Resources and Environment Carrying Capacity in Guangdong Province

[目的]基于资源环境承载力的内涵,从自然资源承载力、社会经济资源承载力、环境承载力3个方面构建了广东省城市资源环境承载力的指标体系,对2016年广东省资源环境承载力进行评价。[方法]运用熵权法对相关指标赋予权重,最终得到2016年广东省各城市的资源环境承载力的评价结果,并在此基础上分析广东省资源环境承载力的格局,最后就评价指标的选取以及资源环境承载力的研究进展方向进行探讨。[结论]①自然资源承载力水平的空间分布格局为"西强东弱",而环境承载力水平的空间分布格局则为"东强西弱";②各市的社会经济资源承载力水平的差距最大,自然资源承载力差距最小,而各市的资源环境综合承载力水平的差距介于环境承载力差距和自然资源承载力差距两者之间;③社会经济资源承载力对资源环境综合承载力水平影响最大,其次是自然资源承载力,环境承载力的影响最小。

[Objective] based on the connotation of resource and environmental carrying capacity, the index system of urban resource and environmental carrying capacity of Guangdong province was constructed from three aspects, namely, natural resource carrying capacity, social and economic resource carrying capacity and environmental carrying capacity, to evaluate the resource and environmental carrying capacity of Guangdong province in 2016.[Methods] the entropy weight method was used to assign weights to relevant indicators, and the final evaluation results of the resource and environmental carrying capacity of cities in Guangdong province by 2016 were obtained. On this basis, the pattern of the resource and environmental carrying capacity in Guangdong province was analyzed. Finally, the selection of evaluation indicators and the research direction of the resource and environmental carrying capacity were discussed.[Conclusion]① the spatial distribution pattern of natural resource carrying capacity level is "strong in the west and weak in the east", while the spatial distribution pattern of environmental carrying capacity level is "strong in the east and weak in the west".② the city’s social and economic resources carrying capacity level gap is the largest, the gap in natural resources carrying capacity is the smallest, and the city’s comprehensive resources and environment carrying capacity level gap between the environmental carrying capacity gap and natural resources carrying capacity gap between the two.③ the bearing capacity of social and economic resources has the largest impact on the comprehensive bearing capacity of resources and environment,followed by the bearing capacity of natural resources and the least impact on the bearing capacity of environment.
