3E系统是指能源—经济—环境系统,3E系统协调度是定量描述特定地区在一定经济发展水平下,能源生产、消费与经济发展、经济结构以及环境承载力、环境保护之间的相互关系,良好的3E系统协调度评价模型能直观地反映出三者能否协调发展。本文介绍了3E系统协调度发展评价指标体系和综合型协调度评价模型,并运用综合型协调度评价模型对四川省近几年的3E协调度进行测算。
The 3E system refers to the energy-economy-environment system. The 3E system coordination degree is a quantitative description of the interrelationship between energy production, consumption and economic development, economic structure, environmental carrying capacity and environmental protection in a given area at a certain level of economic development. Good 3E system coordination evaluation model can intuitively reflect the coordinated development of the three. This paper introduces the evaluation index system and comprehensive coordination degree evaluation model of 3E system coordination degree, and calculates the 3E coordination degree of Sichuan Province in recent years by using the comprehensive coordination degree evaluation model.
