本文在总结国内外城市生态调控研究进展以及熵理论在城市生态学中应用现状的基础上,对基于降低熵增的理论如何应用到城市生态调控的方法进行探索，并提出相应的理论框架和实践方法。本研究将熵理论引入城市生态调控体系，定义了城市生态系统熵，分析其影响因素，并提出了相应的定量化方法。探讨了通过降低城市生态系统熵从而增加系统有序度、维护系统健康的生态调控理论和方法，构建了相应的理论框架和方法体系，为解决城市复合环境问题提供新的调控方法和思路。最后，选择北京市通州区作为研究对象，以2000年到2007年的统计资料为基础，构建城市生态系统熵评价和调控指标体系，采用信息熵计算模型，分析研究区系统熵变情况、发展度和协调度，并根据分析结果制定系统调控方案，经方案验证调整后，输出北京市通州区城镇生态系统熵调控方案。

Based on summarizing the research present situation of urban ecological regulation and the relevant applications of entropy theory in urban ecology field, this paper intended to study on how to apply the entropy theory to the urban eco-system regulation, and proposed the corresponding theoretical framework and practical method. In detail, the paper has defined the entropy of urban ecosystem, analyzed its influential factors and then displayed ways on how to apply the relative quantitative methods. Then the research proved to be able to heighten the degree of order and kept health of the urban ecosystem by reducing the entropy, provided a brand-new idea in the urban eco-system regulation so as to solve the complicated problems in this field. And finally taken Tongzhou district, Beijing as an example.With the statistical data of eight years(2000-2007), the index system of urban eco-system entropy assessment and regulation was built. Then the paper analyzed the entropy changes, development degree and harmonious degree of Tongzhou district by using information entropy model, and at last proposed the regulation plan of the urban eco-system based on analysis results. After the regulation plan was verified and adjusted, the final regulation plan of Tongzhou district, Beijing was output.
