Simulation of Old Urban Residential Area Evolution Based on Complex Adaptive System

On the basis of complex adaptive system theory, this paper proposed an agent-based model of old urban residential area, in which, residents and providers are the two adaptive agents. The behaviors of residents and providers in this model are trained with back propagation and simulated with Swarm software based on environment-rules-agents interaction. This model simulates the evolution of old urban residential area and analyzes the relations between the evolution and urban management with the background of Chaozhou city. As a result, the following are obtained ： （ 1 ） Simulation without government intervention indicates the trend of housing ageing, environmental deterioration, economic depression, and social filtering-down in old urban residential area. If the development of old urban residential area is under control of developers in market, whose desire is profit maximization, and factors such as social justice, historic and culture value will be ignored. （2） If the government carries out some policies and measures which will perfectly serve their original aims, simulation reveals that old urban residential area could be adapted to environment and keep sustainable development. This conclusion emphasizes that government must act as initiator and program maker for guiding residents and other providers directly in the development of old urban residential area.

面向实施的老旧小区改造模式探索--基于低冲击开发理念的借鉴

In the era of stock planning,the renovation of old residential communities has become an important part of urban development in China.However,the renovation planning is difficult to implement.The paper points out three main factors that affect the implementation of old residential community renovation under the current system:complex property right structure,multiple stakeholders,and lack of funds.Based on the concept of Low Impact Development,and with minimizing the impact as the goal,the paper proposes a new mode for the renovation of old residential communities:through an analysis on property rights and interest game in old residential communities,and according to cost estimation,priority should be given to renovating the public elements that neither involve property rights or core interests nor require too many funds,including public space,roads,supporting facilities,etc.,with community management to be properly improved.In the end,with the renovation of Quanyechang Community of Wuhan City as an example,the paper concludes that this renovation mode can not only meet the urgent needs for renovation,but is also easy to implement.

钟摆:中国旧住区改造的70年演进历程

Old residential area regeneration has long been integral to China's urban planning,construction,and governance.This paper divides its history in China into four periods based on the policy and its positioning in the socio-economic pattern:slow development as a non-productive sector(1949to late 1970s),housing marketization under unified planning(late 1970s to early 2000s),a livelihood-oriented transitional period(early 2000s to early 2010s),and a large-scale comprehensive project(early 2010s to the present).It summarizes the positioning,purpose,type,actor,and research characteristics in each period and points out that the old residential area regeneration in China has always been in dynamic interaction between the state,market,and society,presenting complicated characteristics.This process is like a pendulum oscillating between the dual attributes of urban regeneration and housing policies,and relevant studies exploring the Chinese path since 1949 are featured by pragmatism and policy implication.
