Abstract
In this area, the characters seen in present landscape are the product of certain past reclamation processes. For the study of landscape, therefore it is important to analyse the landscape forming process caused by such a reclamation process. In this paper, the author tries to analyse the landscape forming process caused by Tazawa-Sosui and the Second Tazawa Reclamation Work in Akita Prefecture, considering the progress of the work in relation with physical, social and economic conditions in this area. In order to analyse the complex process, the author classified three categories concerning each of the elements which may be interpreted to have a nature of surface, line or point respectively in landscape change.
In the category of surfaces, the landscape in this area has almost changed from forests, grass lands and vegetable fields to rice fields. And corresponding to this change, in the category of lines, the road-, irrigation canal- and ridge between rice fields-networks are newly constructed, and in the category of points, cultivator's houses and pump-houses are built. But the change is not so simple, but is complicated by various conditions of work or areal factor.
Namely, the landscape formation proceeded throughout the changing process caused by reclamation work that operated on each categories in landscape-surface, line and point-, independently or associatedly under interferance of various areal factors.
