摘　　要：生态复杂性与能量密切相关。由于能质不同,传统的能量概念无法定量描述系统的复杂性程度。分析、能值分析是度量生态复杂性的新方法,具有重大的认识论和方法论意义。可以衡量系统目前状态与热力学平衡状态之间的距离,以及体现生态系统所含能量质量的高低;能值分析以统一的太阳能为基准,揭示和比较生态系统中不同等级能量的真实价值与贡献。Ecological complexity is highly correlated to energy. Because of the different quality of energy, it is not correct to use energy as a measure of system complexity. From the angle of epistemology and methodology, analytical theories of exergy and emergy is new methods for measuring ecological complexity. Exergy gives a good measure of the complexity of a system and its distance from equilibrium, of the quality of system energy. Emergy may be used to evaluate quantitatively energy flows through uniform solar energy, so as to disclose and compare biological and economic systems , which is grounded in actual value and contributions of different gradients energy.
