Abstract
The purpose of this paper is to deduce the optimal land-use type from the viewpoint of regional planning. The whole area of Aichi Prefecture was divided into 5, 142 standard meshes (grids), and for each mesh, 17 variables were examined to determine the types of land-use.
Adopted variables are as followings;
A. Physiographic factors: (1) elevation, (2) relief energy (land relief) (3) drainage density (density of valleys) (4) gradient of land, (5) practically utilizable amounts of ground water, (6) potential of ground water, (7) fertility of farm land, and (8) fertility of forest.
B. Distance factors: time-distace to, (1) Nagoya, (2) regional centers, (3) freight terminals, (4) railway stations, and (5) highway interchanges.
C. Social factors: (1) forest reservation, (2) improved faun land, (3) irrigated up-land fields, and (4) density of road networks.
Five types of land-use (residential, commercial, industrial, agricultural, and forestal) were predesigned by factorial analysis. These types were individually diiend by control-ling the difinite amounts of area coverage in a mesh. The satisfied meshes (grids) were named here “typical”. By this procedure, 1, 037 meshes were accounted for “typical” ones and their numbers corresponding to each type of land-use were shown in Table 1. The ratio of discriminant power is accounted for 87.7 percent. The discriminant functions were listed in Table 2. The largest discriminant scores for each mesh were culculated employing those functions and they were utilized for the computer mapping (Figure 1).
