自组织视角下建筑废弃物减量化系统的协同机理与演化模式研究

It is determined that there are kinds of complicated connections among the processes, activities and stakeholders involved in construction waste reduction (CWR), and these elements have all together formed an integrated system with a capacity of self-organizing. However, there is a lack of research investigating the characteristic of self-organization of the system, which affects the overall effectiveness of CWR practices. This project, therefore, aims to address the research gap by examining the synergetic mechanism and evolution model of CWR system based on the self-organizing theory. Specifically, the elements driving the development of CWR will be firstly identified and a structure model depicting the relations among the dynamic elements will be developed. Then how the dynamic element of the CWR system forms a dissipative structure will be examined both from a qualitative and a quantitative perspective. Through identification and analysis of the order parameters in the system, its synergetic mechanism and dynamic model will be investigated. After that, the conditions causing the evolution of the dynamic model will be analyzed and a model describing the evolution process of the dynamic model will be developed. Finally, a validated policy framework used to promote CWR practices will be proposed in line with the order parameters and the synergetic development of the system. The real characteristics of the CWR system can be better reflected by this project which focuses mainly on the complexities and self-organizing characteristics of the system. It is expected that the research outcomes will not only contribute to the development of existing studies on CWR, but also will promote the overall effectiveness of implementing the CWR policies.

建筑废弃物减量化所涉及的过程、活动、利益相关者等要素间存在着复杂的作用关系，共同构成了一个有机的自组织系统。然而，前人学者并未对该系统的自组织特性和规律开展深入研究，制约了建筑废弃物减量化整体水平的有效提升。本项目拟基于自组织理论，探讨建筑废弃物减量化系统的协同机理与演化模式，具体包括：识别建筑废弃物减量化发展的动力要素，构建系统发展动力的结构模型；从定性和定量两方面深入分析废弃物减量化发展动力系统形成耗散结构的判据；通过识别、分析动力系统的序参量，研究系统发展的协同机理和动力模式；分析动力模式演化的诱发条件并建立动力模式的演化过程模型；最终，从序参量和系统协同发展两方面构建提升建筑废弃物减量化水平的政策体系并验证其合理性和有效性。本项目立足于建筑废弃物减量化系统的复杂性和自组织特性，更能反映系统的实际情况，在丰富建筑废弃物减量化理论研究的同时，也能提升废弃物减量化政策的科学性与合理性。
