苏州古城容量综合评估与优化决策研究

A STUDY ON THE COMPREHENSIVE EVALUATION AND DECISION OPTIMIZATION OF SUZHOU OLD TOWN CAPACITY

在长期严格的保护控制政策引导下,苏州完好保存延续了古城传统风貌与空间格局。进入新的发展阶段,苏州古城面临着人口老龄化、基础设施不完善、交通出行不便、居住环境品质下降及城市活力不足等困境与挑战,急需改进现有古城容量管控方法,因地制宜提出古城更新策略。针对这一现实需求,围绕古城传统风貌保护、宜居环境改善和城市活力提升的整体协同,基于多维角度、多个目标和多种情景,从容量评估约束条件研判、分项维度适应性容量模型测算、多情景综合容量方案生成和综合容量多方案比选等方面,对苏州古城容量的综合评估与优化决策进行了研究,以期对提高古城容量管控的科学性、系统性和可操作性及促进古城活力提升与可持续发展具有重要作用。

Under the long-term strict protection and control policies,Suzhou has been well preserved to continue the traditional style and spatial pattern of the old town.In the new stage of development,Suzhou Old Town is facing many difficulties and problems,in terms of the aging population,imperfect infrastructure,inconvenient transportation,declining living environment quality,and insufficient urban vitality.It is urgent to improve the existing capacity control methods and propose the regeneration policy according to local conditions.Given this practical demand,focusing on the overall coordination of the protection of the traditional features of the old town,the improvement of the livable environment,and the promotion of urban vitality,the comprehensive evaluation and decision optimization of the capacity of Suzhou Old Town are studied from multiple perspectives,objectives,and scenarios.This paper analyzes the constraints of the capacity evaluation,establishes models for the calculation of subitem dimension adaptive capacity,provides multiscenario comprehensive capacity schemes,and compares the comprehensive capacity schemes.It is of great significance to improve the scientificity,systematization,and operability of the capacity management and control of the old town and to promote the vitality and sustainable development.
