Abstract
In oldsthe nature is likely to be clearly differentiating their personal space from another. For example, in homes for the aged, when multi-residents live in a room, each man makes barriers by tatamis' edge and occupy in this enclosed space. And if others' articles or sleeping beds put in their enclosed space, immediately they put off them. Also because their behavior are not active for degenerated physical strength, they are enclosed them in small life space rather than extend it. So usually we find them in sitting all day idly. But by still more observation, they like rooms' corner, so in 4 beds room they scattered in 4 corners. Sum up them, it be assumed that old people occupied the territory as like as birds in nesting time. Then I tried an actual surved even whether they have occupied territories actually, or what kinds of actions influence to them by spatial and humanistic factors. And I considered that to make use of ecological principles. The results of the survey show that old people have occupied territories and folloing ecological principles have been extracted. So that : 1) principle of adjustment to inorganic enviroment, 2) classification system, 3) order system, 4 effect of pre-living, 5) cooperation system, 6) effect of density, 7) effect of group, and 8) development by time. These are very important theories for home planning for the aged and so on.
