基于系统动力学的城市更新改造综合效益研究

随着我国城市化进程的不断深入推进，面向城市更新的效益评价研究显得尤为重要。立足于广州市石溪村城市更新实践，选取相关影响因素指标，构建城市更新综合效益评价模型。基于系统动力学，对石溪村城市更新项目的综合效益进行预测，包括经济、社会和环境3个子系统。研究发现，利润是影响经济效益的主要因素，人口流动量与交通通达度是影响社会效益的主要因素，建筑物全生命周期的碳排放是影响城市更新环境效益的主要因素。根据研究结果，提出促进城市更新与城市可持续发展的建议。

Research on Comprehensive Benefits of Urban Renewal and Reconstruction Based on System Dynamics

With the continuous advancement of urbanization in China, the research on the benefit evaluation of urban renewal has become particularly important. Based on the practice of urban renewal in Shixi Village, Guangzhou City, relevant influencing factors is selected to construct a comprehensive benefit evaluation model of urban renewal. Based on system dynamics, the comprehensive benefit of Shixi Village urban renewal project is predicted, which includes three subsystems: economy, society and environment. The results show that profit is the main factor affecting economic benefits, population mobility and traffic accessibility are the main factors affecting social benefits, and the carbon emission of buildings throughout their life cycle is the main factor affecting environmental benefits of urban renewal. According to the research results, some suggestions are put forward to promote the sustainable development of urban renewal and urban development.
