摘要:

容积率是描述城市土地开发强度的重要指标,在人地矛盾日益尖锐的今天,“高容积、低密度”的城市开发思想得到人们的青睐,然而当该政策实施于实践中时,却暴露出很多的问题,如交通堵塞、日照不足、易发火灾等,严重影响着人们的身心健康和城市的可持续发展.如何合理确定建筑容积率成为当前研究的焦点.文章从容积率的概念、特征、影响因素等方面入手,对城市规划中的容积率进行研究和分析,包括容积率对地价的影响、现状容积率的估算和规划容积率的确定.比较了城市地价评估中容积率修正系数确定方法的优缺点,阐述了高分辨率遥感影像在城市现状容积率估算中的应用及进展,探索了一条确定合理容积率的有效途径——综合平衡法.通过对容积率研究脉络的梳理,得出环境容量限制将是制约容积率提高的瓶颈,试图探索一种基于3DCM日照分析模型的极限容积率的求取方法.

Abstract:

FAR(Floor Area Ratio)is an an important indicator of describing the intensity of urban land development. At present, the contradiction between people and land is becoming increasingly acute. The urban development principle of “High volume, low density” has been widely accepted. However, a lot of problems were exposed when the policy implemented in practice, such as traffic jam, lack of sunlight and fire-threat. These problems affected people's health and cities’ sustainable development seriously. How to determine a rational FAR becomes a current research focus.This paper started with the concept, characteristics and influencing factors of FAR (Floor Area Ratio), researched and analyzed the FAR in urban planning, including the effects of FAR on land price, the estimation of present floor area ratio and the determination of planning plot ratio, compared the advantages and disadvantages of methods which can determine the correction coefficient in assessing urban land price, expounded the application and development of high resolution satellite imagery in estimating the present FAR of a city, explored an effective approach to determine the rational FAR values—comprehensive balance method, found out that the bottleneck that limits the increase of FAR was environmental capacity by carding the research history of FAR, tried to explore a method for estimating maximum FAR by using the 3DCM sunshine analysis model, and determined the future study focus of FAR.
