株洲城市生态系统能值综合分析

Energy synthesis analysis on ecosystem of Zhuzhou City

以株洲市为研究对象,应用基于系统生态学、生态能量学和生态经济学的最新能值分析理论和方法,以能值为基准,定量分析株洲城市复合生态系统的物流、能流、人口流等基本生态流以及货币流;建立了一套可比较的能值综合指标体系,探讨了生态流变化过程与城市发展的关系,分析和比较了株洲与西方发达城市的差异,为株洲市可持续发展提供科学依据和决策参考。株洲城市生态系统的总应用能值主要由本地区的可更新资源、购进燃料以及电力、输出商品劳务等能值构成。株洲经济的高速发展是建立在自然环境压力增加的基础上。从长远利益和宏观角度出发,株洲应充分发挥自身的资源优势,协调各种能值来源的比例,确保其能值结构的合理性,最终加速经济发展和提高竞争力。

Taking Zhuzhou City as a research sample with application of theory of emergy analysis, which is based on systematical ecology, energetic ecology and ecological economics. The quantitative analysis was based on physical flow, energy flow, and population flow of Zhuzhou City in terms of emergy. We proposed an emergy-hased evaluation system, analyzed the relatiouship between ecoflow and city development, and also differentiated Zhuzhou city from developed cities in western countries. The total emergy value of Zhuzhou urban eco-system is made up of renewable resources, purchased fuel and electricity, and exported services and labors. The fast development of Zhuzhou economy is made with an increase of pressure on natural environment. From the point of long-term interests, Zhuzhou city should make good use of its resources, coordinate various of source of emergy, and ensure an optimized cmergy structure, to quicken its economical development and improve its competitiveness.
