Abstract
The purpose of this thesis is to clarify a physical characteristics of the mixed area of residence and industry as a parameter for the planning in a case of both redevelopment and reallocation of residence and industry within the same area. It is almost imposible to move the small scale factories out of the existing area. Because, they have a deep relationship among them and, moreaver, they lack the budget for moving to an industrial area. The six districts (approximately one square kilometer) are selected as a sample from the Tokyo metropolitam Region. They are actually surveyed and analysed according to road area, building area, floor area, openspace, mean number of stories and building use. All items are estimated by a mesh analysis. In this case, a size of each mesh is 5 meters by 5 meters.
