Research for the preservation of bamboo forest as the amenity in urban development area:

The Interest to the residence environment of people is transforming from material sufficiency to mental one. That is being satisfied from the improvement of the standard of living to the environmental quality. From such a background, words of the amenity attract attention today. The amenity is utilized in various situations such as sound environment or barrier free, but the amenity formation is used for the natural environments of the particularly local inimitableness. Their importance is spoken in the environmental white paper. This study is pushed forward in many aspects about the maintenance of such natural environments, and is recognized widely. However, there are few studies of the maintenance method about the bamboo forest that it is agriculture and forestry place. The investigation for their present conditions is insufficient still more. At first, we investigate a process of urban development and the maintenance for bamboo forest by documents and hearing according to the present time. From them, it is compared the difference of amenity awareness and the consciousness about bamboo forest. Their difference between handed down conventional inhabitants and new arrival inhabitants will be found out with a questionnaire next. The investigation area is Nagaokakyo city, Kyoto prefecture. It is the area where urbanization drastically has been advanced from the highly economic growth period to the present in this city, and the urban development is advancing now. In this study, we performed a questionnaire survey to compare the amenity awareness with comparison of the bamboo forest value awareness between old arrival inhabitants and new arrival inhabitants. All the replies number of questionnaires was 197 from 800 household in Nagaokakyo city. As a result, the nearer area to the city center can be said that the interest to the investigation about bamboo forest was low. By the question to ask bamboo forest knowledge, it may be said that there are more few people knowing the present conditions of bamboo forest in Nagaokakyo city. By next questionnaire is to ask amenity awareness. The most typical answer is there was much nature by neighborhood to ask an amenity element of an ease on agreeableness of a city and living environment. There was the place that could come in contact with nature near is most representative to ask substantiality degree of an institution, service related to education, culture and a hobby of a neighborhood. It followed that called nature for an element of amenity was the most important with both questions. In addition, by a question of an amenity item of questionnaire, the interest to an ease and moisture of natural environments was high in old arrival inhabitants. On the other hand, it followed that the interest of convenience of traffic in life was the highest in new arrival inhabitants. The maintenance of bamboo forest in Nagaokakyo city can be said to be an advanced example in the formation of the amenity awareness as to the tradition of the bamboo shoot production or the aggressiveness of the volunteer activity. However, the maintenance method for bamboo forest through many residents can be satisfied. It is not always that they got ready by a residence career and breaking off a difference with the interests to the residence environment. In the future, we will check the value awareness to the environment of the resident by asking WTP to the CVM which we used it by questionnaire survey. It will be necessary to do it with the indicator of the ecological viewpoint. Nagaokakyo city is the bedroom suburb, included in an industrial district, farmland and the mountainous district. It is thought that we were provided for much knowledge that even other areas can refer to from this investigation.
