Planning Approach to Land Use Structurization (3)

Planning Units for Land Use

Abstract

There are many physical units that relate to land which are useful in analysis, synthesis and planning required in planning studies. Generally, several scales of meshes and: or administrative districts are used as basic units. Also, watersheds have become an important unit in natural land use planning.
In this study, the relationship between the units and the regional characteristics are discussed. This is followed by a discussion of the relationship between land use and natural land conditions.
Finally, planning units based on watersheds are proposed for land use planning in the Sennan region of Osaka prefecture. These planning units are formed in two steps. Watersheds are used as the basic units, then these units are subdivided using ridges, rivers roads and/or railways as boundaries. These smaller units are used for gathering land use and land conditioh data. The process used in defining the units is descrived below:
(1) determine the basic river and its course indicated on the map (1/30, 000).
(2) define those watershed with ridges, etc.
(3) divide each watersheds into mountain, hill and flat zones.
(4) determine the subdivided units as in steps 1-3.
Land use data were gathered according to the basic and subdivided units and the subdivided units relating to the main ridges of the watershed were checked. These are shown in figure 13. However, land use planning maps based on the natural land potential should be proposed.
