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同时，建立正确把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，分别从城市规划区、城市化推进区和城市化控制区三个方面分析了城市人口密度分布结构与建筑活动的关系。首先，把握了日本近年来城市的宏观特征及其时间序列变迁。通过对《城市规划年鉴》中5万人口以上城市的数据分析，将城市地域结构划分为9类，其中城市规划区、城市化推进区和人口密集区形成同心圆结构。分析了城市的地域结构与城市的位置、规模等属性的关系。其次，根据新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，计算出每人口的建筑面积单位。通过对这些指标的分析，探讨了城市地域结构特征与城市建设活动的关系.第三，以金泽市为例，分析了以地方法规为基础的土地利用分区或规划控制与土地利用结构的关系。作为结论之一，今后要构建城市土地利用规划控制体系，必须明确城市土地利用规划控制体系与土地利用结构变迁的关系。

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.
