解决生态环境问题必须有赖于科学技术的进步,对生态环境问题的正确评价,是认识生态环境问题的首要问题。20世纪末,学术界提出了许多生态环境评价理论和方法,能值理论是重要的理论和方法之一。本文对能值理论进行了简要的回顾与评价,在此基础上,提出了用于评价区域可持续发展的四维能值理论。分析表明,四维能值理论方法综合考虑了世界人口和时间等要素,完善了能值理论在反映生态环境过程中的不足,四维能值理论的指标对于评价生态环境现状、预测生态环境未来趋势以及帮助决策者在制定长远政策等方面都具有一定的指导意义。
To solve the problem of ecological environment must depend on the progress of science and technology. The correct evaluation of the problem of ecological environment is the primary issue to recognize the problem of ecological environment. At the end of the 20th century, many academic circles put forward many theories and methods of ecological environment assessment. Emergy theory is one of the most important theories and methods. In this paper, a brief review and appraisal of emergy theory is carried out. On this basis, a four-dimensional emergy theory is proposed to evaluate the sustainable development of the region. The analysis shows that the four-dimensional emergy theory method synthetically considers such factors as world population and time, perfects the insufficiency of emergy theory in the process of reflecting the ecological environment, and the four-dimensional emergy theory index is of great significance for evaluating the current situation of the ecological environment, predicting the future trend of the ecological environment and Help policy-makers in the formulation of long-term policies and so has a certain significance.
