基于GIS的旧城改造开发容量的研究——以南阳市旧城更新改造为例
|
摘要
随着城市化进程的不断推进,旧城改造已经成为我国目前城市建设的重要任务,如何有效地进行旧城更新改造,对我国城市发展战略具有重要的意义。文章从城市经济定量分析角度入手,提出了旧城改造开发容量的概念、模型,土地等级评价指标体系及计算土地等级评价因素权重的AHP模型;以旧城生态环境和社会环境为约束条件,以经济作为目标函数,提出了基于旧城生态环境容量和社会环境目标确定旧城开发容量的上限模型,及基于市场行为的经济目标确定旧城开发容量的下限模型,使旧城改造始终处于经济、社会、环境持续协调发展的有序控制之中;并以ARCGIS为平台,结合南阳市旧城改造规划设计研究,得出旧城改造开发强度专题数据地图,对在GIS平台下合理确定旧城改造的开发容量,进行了尝试性探索。
Along with the process of urbanization,the old-town renewal has become the top task in the city construction.Directed by quantitative analysis of city's economy,this paper puts forward a new conception and model of development capacity for old city renewal,established land class evaluation system and AHP model to determine the land class and its evaluation factors.Restricted by the old town's eco-environment and social environment,and targeted by its economy,this paper suggests that the upper limit model of the old city's development capacity should be decided by its eco-environment volume and social environment,and the lower limit model should be determined by the market economy,thus the renewal can see the economy,society and environment proceed orderly and harmoniously.Upon the platform of ARCGIS with considering Nanyang old town renewal planning and design,this paper has drawn a digital map for old town renewal development intensity,and explores tentatively the proper development capacity under the platform of GIS.
