仙台南部の都市化に伴う土地利用秩序の変容過程

Abstract

Progress of housing development in urban fringes has brought the large-scale transformation of land use ordination in the recent decades. The purpose of this study is to understand the historically constructed structure of land use ordination and its transformation process. In particular, theinfluences of land use control technique (zoning procedure) and natural conditions on land use changes are taken into consideration. Southern Sendai area including parts of Sendai-shi (Prefectural Capital) and Natori-shi is selected as a caseto study. The zoning of this area includes the urbanization promotion area the agricultural promotion area (the exclusive agricultural zone and the agricultural district zone), the provisional rezoning area, and the unzoning area. The map of natural land units indicated by landforms and soils presents different natural conditions which have historically determined the land use ordination of this area. Recent trends in land use changes are evaluated in terms of land suitability presented by natural conditions. Followings are the significant problems in this area; 1) the expansion of housing development on unsuitable site, 2) the concentration of commercial and industrial land use on unsuitable wet lands where paddy fields have been historically developed. and 3) increasing of public land use in the urbanization control area. In every zone, the relationship between zoning procedure and natural conditions is examined. As a result, it is concluded that the natural conditions have not sufficiently taken into consideration in zoning procedure. For the presentation of optimal land use zoning in the planning process, each zone should be drawn based on both social and natural conditions.
