A Research Of Participation Model And Commensal Profit Mechanism Of Old Urban Residential Area Sustainable Improvement

The development history of city is the constant metabolism course. With the quickening urbanization process, the old city's own adapting mechanism is unable to continue working and the new problems on material, economic, environmental and social aspects are emerging out continuously, particularly in old urban residential area, which we should face in the development process of every city around the world. Complex Adaptive System is in front line of systematic science and focuses on systematic principle, mechanism and evolvement from microcosmic to macroscopic. Referring to Complex Adaptive System, this thesis regards the old urban residential area as the complex system and considers that the environmental adaptive capacity and sustainable development ability of old urban residential area is emerged in each individual interaction and the interaction between environment and individual. What's more this thesis puts forward the participation model based on CAS and sets up the commensal profit mechanism of old urban residential area sustainable improvement. Firstly, the thesis takes the sustainable development theory as the basic point, empahsizes its foundation: government guiding and public participation, and then analyses public participate theory, next summarizes the development and application of public participation in urban renewal in domestic and abroad; Secondly, this thesis analyses basic feature composition, corresponding problems and historical evolvement of the old urban residential area in the background Jiang'an district, Wuhan, and puts forward the sustainable improvement goal with the application of public participation. After giving a brief introduction of Complex Adaptive System, this thesis uses it to explain sustainable improvement, in addition defines the complex adptive character of old urban residential area , the applicability of CAS and some edification; Thirdly, this thesis analyzes the feature, classification, behavior rule of participator in old urban residential area and the "gravitating and driving power" function of the environment, in order to set up the participation model of old urban residential area sustainable improvement based on CAS in three aspects of goal, organization, and mechanism. Finally, the current organized mechanism of implementing public participation in old urban residential area sustainable improvement is discussed, and the commensal profit mechanism is advanced by studying its sub-system and actualizing safeguard. This thesis takes SWARM software as platform to simulate part of the participation model and mechanism and provides relevant proposes to fulfill.
