摘要
区域人口、资源、环境和经济发展的综合协调是促进区域可持续发展的有效途径。以南宁市为例,通过对南宁市2005—2012年PRED系统发展状况进行分析,建立区域人口、资源、环境、发展循环复合系统,构建区域PRED系统综合评价指标体系,采用熵值法和综合评价法,构建区域PRED系统综合评价模型,计算区域各系统的协调度。结果表明,南宁市区域PRED系统整体上处于可持续发展状态,其中,综合协调度在2008年和2010年分别有不同程度的下降,其余年间均呈现上升状态。南宁市应该在总结过去发展经验的基础上,进一步走可持续发展之路,优化人口结构,重视资源合理利用与环境保护,积极发展对外型经济。
The unisonous development among population,resources,environment and economy is effective to promote the regional sustainable development. This paper,based on a case study on Nanning,analyzes Nanning＇s PRED＇s development in 2005-2012,establishes circular composite system of regional population,resources,environment and development,and sets up comprehensive evaluation index system of regional PRED system by using entropy and comprehensive evaluation,which is used to measure each system＇s coordination degree. Nanning＇s PRED system in majority is in sustainable development. Its comprehensive coordination fell in 2008 and in 2010,but rose in rest years.This paper suggests Nanning shall go further in sustainable development based on the past experiences in optimizing popular structure,caring resources utilization and environmental protection,and actively developing external-oriented economy.
