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.

Key words: correction coefficient, floor area ratio, integrated balance method, satellite image
