In Japan, the methodological study for environmental planning has not been established yet. The purpose of this study is to propose a methodology and to adopt a field survey on a local landscape. From the landscape ecological aspects, we define that areal landscape is composed by three components : 'anorganische Welt', 'vital Welt' and 'geistbestimme Welt' in German sense. Physiotope and biotope which might be corresponded to 'anorganische Welt' and 'vital Welt', are treated as one unit of ecotope. Questionnaire assigns to inspect 'geistbestimme Welt'. The spacial pattern of ecotope overlaid by landform, surface geology, soil and vegetation is found out among the newly data-based ecotope. This pattern which successfully expressed the actual landscape of Setoda was principally judged the formation of natural landscape. By questionnaire, social identity for community and the concerns of inhabitants in Setoda were collected successfully. The inhabitants prefered both the natural and artificial well-managed sites in Setoda. While they did not prefer the unmanaged artificial sites. Some sites designated by inhabitants were different to sites as well-known natural landscapes. From these procedures, the extracted sites from questionnaire were identified as psychocultural/imaged landscape based on culture and social aspects. We found that the dominant ecotopes usually distribute widely and establish the community identity, and they influence to inhabitants to recognize the landscape. The main understanding way of landscape in this island comes from 'anorganische Welt' and 'vital Welt' at first, and then they affect 'geistbestimme Welt' secondary. Of course these three components are interacted each other. We also argue that local landscape structure such as the study area must be to investigate before the planning stage, and this step is needed to ask in the course of planning.
