４地目筆地分級の概念と性格 集落土地利用計画の合理的策定のための４地目型筆地分級手法の開発（１）

Abstract

This study was accomplished on the method of the low-level land suitability classification (LLLSC), called “Hichi-Bunkyu”, in which a land is classified into one of the 4 land utilization types with a view to the rational land use planning in rural villages. The concept of 4 land utilization types is as follows: i) “Sangyo-nouchi”, which is agricultural land suitable for large-sized agricultural machines, and aims at to the economical returns for such farmers, as ones with an enterprise farming system and a profession farming system. ii) “Hi-sangyo-nochi”. means agricultural land which gives plesure of being a farmer for a person living in city, a retired person, and a farmer with a side job who produces the foods for himself. iii) “Sisetsu-youchi”, is a land for houses, public facilities, rural factories, and village infrastructures. iv) “Seitaikei·Amenity-youchi”, is the important functional land for conservation of the nature, environment, landscape, and ecology, as well as the amenity in the rural area.The results obtained in this study are summarized as follows; 1) Land use suitability of Sangyo-nouchi is high in the place where land size is large and agricultural lands concentrate. It shows a mass and collective characteristics of Sangyo-nouchi.2) However, Hi-sangyo-nouchi has high landuse suitability in the place where land size is relatively small and close to residental areas. The suitable lands of Hi-sangyo-nouchi are scattered as compared with lands suitable for other uses.3) Sisetsu-youchi shows high land use suitability in areas presently used for residences, factories, public facilities, and areas close to these categories. The land use suitability of Sisetsu-youchi has almost the opposite trends in comparison with that of Sangyo-nouchi and Hi-sangyo-nouchi.4) Land use suitability of Seitaikei·Amenity-youchi is found to be high in the forest, wasts lands, fruit farms, and houses which have woods and surrounded by forests. The land suitable for Seitaikei·Amenity tends to be found also appropriate for otheruses (Sangyo-nouchi, Hi-sangyo-nouchi and Sisetsu-youchi) .
