Transition of land use structure by city planning institution in city region and its planning control

在编制城市总体规划的背景下，建立掌握土地利用结构的规划方法和规划控制体系是十分重要的。利用已有的统计数据，参照城市规划区、城市化促进区和城市化控制区，分析了城市人口密度分布结构与建筑活动的关系。首先，掌握了近年来日本城市区域的宏观特征及其时间序列转换。通过对《城市规划年审》5万人口以上城市数据的分析，将城市区域结构分为9类，其中城市规划区、城市化促进区和人口密集区为同心圆结构。分析了其与城市区位、城市规模等城市区域结构和属性的关系。其次，利用新建建筑统计的建筑面积及其使用情况，以及全国人口普查的各种人口统计数据来计算单位人口建筑面积。通过对这些指标的分析，揭示了城市区域结构特征与建筑活动的关系。采用多元回归分析对地级市和各地级市进行了分析。第三，以金泽市为例，分析了土地利用分区或地方性规划控制与土地利用结构的关系。作为结束语之一，今后要构建城市土地利用控制规划制度，必须厘清这一制度与土地利用结构转型的关系。

It is important to establish the planning method in order to grasp land use structure and the system of the planning control on the occasion of planning the city master plan. Using existing statistical data relationship between population density distribution structure in urban area and building activities are analyzed referring to Urban Planning Area, Urbanization Promoting Area and Urbanization Control Area.First, macro characteristics of urban area in recent years of Japan and its time series transition are grasped. Urban area structure is classified into nine categories by analyzing data of above 50,000 population cities from the City Planning Annual Reviews, in which Urban Planning Area, Urbanization Promoting Area and Densely Inhabited Districts from as concentric circle structure. Relationship with urban area structure and attributes such as the location and the scale of cities is analyzed.Second, building floor area with its usage from newly building statistics, and various demographic statistics from National Census are used to calculate a building floor area unit per population. Analyzing these indices, relationship between characteristics of urban area structure and building activities. It is primarily analyzed at prefectural level and each city level using multiple regression analysis.Third, relationship between land use zoning or planning control on the basis of an own bylaw and land use structure is analyzed in Kanazawa City as a case study. As one of concluding remarks a system a city planning of land use control is to be constructed from now on and relationship between this system and land use structure transition must be clarified.
