SELF-ORGANIZED TIME-SPATIAL EVOLUTION MECHANISM OF URBAN-RURAL GREEN SPACE SYSTEM FROM THE PERSPECTIVE OF ORGANIC RENEWAL IN SHANGHAI

Study of time-spatial evolution based on self-organization theory can extract and reveal the internal order and the law of development which is organic renewal must be clear first, and guide the implementation direction and strategy of spatial intervention. On the basis of the explanation of the connotation of self-organization concept, this paper clarify the research sequence of self-organized time-spatial evolution, and interpret the complexity of urban-rural green space system as self-organizing system. Through the analysis of self-creation and maintenance, self-expansion and self-evolution of urban-rural green space system, it explained the mechanism of self-organization time-spatial evolution, including the dynamic mechanism of competition and coordination, the order parameter as the dominating factor, the time-spatial order of dissipative structure and the spatial agglomeration of green attractor, then pointed out that spatial intervention should conform to and promote these key points, so as to achieve the coordination of subjective planning decision-making and objective self-organization laws, and promoted the spiral upward process of the time-spatial evolution of urban-rural green space system.
