基于脆性分析的西安城中村改造系统评价

以西安市城中村为例,对其城中村改造系统进行评价。基于脆性理论分析影响城中村改造的因素并在此基础上进行多层次矛盾分解,建立评价指标体系;结合模糊数学理论,利用突变理论建立数学模型,求解突变隶属函数,得到评价结果;解读西安城中村改造政策并探讨新方向。实际应用表明,突变级数评价法客观有效,为城中村改造的评价和调控提供了新的思路,而应用复杂系统脆性理论对城中村改造进行研究探索,对当前城市建设具有一定的指导意义和借鉴作用。

Renovation System Evaluation of Urban Villages in Xi' an City Based on Brittleness Analysis

Renovation system of urban villages in Xi’an City was evaluated.Influence factors of urban village renovation were analyzed on the basis of brittleness theory,and an evaluation index system established through multi-level inconsistency decomposing.By incorporating the catastrophe theory with fuzzy mathematical theory,the mathematic model was created,and catastrophe membership function was obtained as well as evaluation results.Policies for the renovation of urban villages and new direction of the renovation were interpreted.The application case proved that catastrophe progression method was objective and effective and it could provide new concepts for the evaluation and adjustment of urban village renovation.Moreover,application of brittleness theory in the research on urban village renovation is of great instruction and reference value for the present urban construction.
