広域における土地利用の域形成と土地利用種目混在の分布構造に関する研究

In this study, we investigated the structure of land use distribution at great area through the use of the land use category data by mesh and prefecture unit. We divided into land use categories, high density build-up land, low density build-up land and miscellaneous land as spatial use land, rice field, cropland, orchard and plantation as agricultural use land, woodland, moor and water front as unused land. The summary of the results are as follows : 1. The population structure of every prefecture can be categorize into six pattern and the alteration of the land use structure in every prefecture have two main tendency, one is the increase of urban land use, the other is the increase of forest. 2. On national scale, every category of land use organizes high density zones and low density zones. The spatial use land forms two great zones by density, and high density zone shapes concentric-zone structure, high percentage units are consentrating at center and low ones are spreading around. The agricultural land make different structure by categories. 3. The hightest mixing rate between land use categories is that of low densiy build-up land use in other land use category. The rate become higher in urbanized region, lower in agricultural region. 4. The correlation between spatial use land and other land use category decrease in urbanized region, increase in agricultural region.
