過疎地域における中心集落との関係からみた集落の分布構造に関する研究

Abstract

We select depopulated municipality of SHIMANE prefecture in which population especially decrease as a subject of investigation and perceive various condition of population dynamics by making agricultural villages which is minimum regional society of a unit for analysis.In this study, we realize the structure of distribution of the village types by population dynamics that were got. Then we pay attention to the term of convenience, central convenient function level, that have relevant especially to the types, and we replace it with relation between each village and the key sattlement. By that we realize the distribution of the village types by population dynamics.Conclusions are as follows:1. We investigate distribution of village types by population dynamics from the point of view which is distance or difference of height between villages and key settlement. Consequently it become clear that distribution of the types is can be grasped the structure of core which have the center of key settlement in a unit of old villages, and accumulation of convenient function in key settlement make stably all area of old village.2. We couldn't get direct correspondence between population and condition of agriculture. However we check up them again using land location of distance and deference of height between each village and the key settlement. As a result the qualification that prescribe population types is different in each condition of agriculture. And ordinary prerequisites of stable type depend on location of relation with key settlement but the stable type of middle or small scale can exist on the places where are far from key settlement. Then prerequisite is preparedness of basic condition of agriculture.Dispersing of central convenient functions in micro scale by that in area of old village where we maintain the key settlements is necessary for stabilizing population.
