Abstract
Master plan for municipalities is to be appropriately formulated, to indicate the basic direction of urban development and land use. The natural environmental conservation should be included therein. However, such information as the transformation of natural environment and the living space and presence of animals and plants is difficult to be obtained from the geographic information only. For this purpose, we used oral history interview technique. Asking the people living in the case study area of Hadano, Kanagawa Prefecture, we obtained the information for natural environmental conservation, and combined it with the geographic information. This paper describes the result of the combination, and clarifies the effectiveness and the problems to be improved.
