摘要:
[目的] 对粤北山区5市的社会—生态—经济系统的恢复力进行测度和协调度评价,为欠发达地区的可持续发展提供理论基础。[方法] 以恢复力的视角构建了社会—生态—经济耦合系统的理论框架和评价体系,并建立二元和三元协调度模型。[结果] ①社会—经济—生态系统恢复力总体上升,社会子系统和经济子系统恢复力增速较为缓慢,生态子系统恢复力有所下降;②社会—经济—生态系统恢复力等级空间明显,社会子系统恢复力等级升高,呈现“四周高中间低”的特点,经济系统恢复力呈现出“东高西低”的特征,生态子系统恢复力等级出现了下降的趋势。③生态—经济系统濒临失调,社会—生态系统基本协调,社会—经济系统初级协调;社会—生态—经济系统协调度仍然处于轻度失调阶段。[结论] 粤北地区耦合系统的恢复力有待提高,特别是生态系统恢复力。后期应该注重社会—生态—经济系统的协调和和互动能力。

Abstract:
[Objective] The resilience and coordination degree of the social-ecological-economic system of five cities in the mountainous areas of northern Guangdong Province were measured to provide a theoretical basis for the sustainable development of underdeveloped areas.[Methods] From the perspective of resilience, this study constructed a theoretical framework and evaluation method of the social-ecological-economic coupling system, and established binary and ternary coordination-degree models.[Results] ① The resilience of the social-economic-ecological system generally increased; the resilience of the social and economic subsystems increased relatively slowly, whereas the resilience of the ecological subsystem decreased. ② The resilience level of the social-economic-ecological system was obvious. For example, the resilience level of the social subsystem increased, and exhibited the characteristics of being high in the surrounding areas and low in the central area. In contrast, the resilience level of the economic system exhibited a downward trend, and was high in the east and low in the west. ③ The ecological-economic system was on the verge of maladjustment, the social-ecological system was basically coordinated, and the social-economic system was primary coordinated; hence, the social-ecological-economic system was in the stage of slight maladjustment.[Conclusion] The resilience of the coupling system in Northern Guangdong Province needs to be improved, especially with respect to the ecosystem. In the future, close attention should be given to the coordination and interaction of the social-ecological-economic system in Northern Guangdong Province.
