自己組織化マップを用いた福岡市民の水に関するアンケート調査結果分析

摘要

It is assumed that the citizen in Fukuoka City has a consciousness of water saving because they suffered from water shortage in 1978 and 1994. To investigate the citizen's interest in water, questionnaire survey was carried out by Fukuoka City Office in 2007.In the present study, the result of the survey was examined by using Self- Organizing Map (SOM). The citizen was divided into 7 groups. The characteristic of each group was analyzed.As a result, it is found that young people in the age of 20's and 30's and people who live in the central area are seen in the group of having less interest in water saving. The elderly citizens in the age of over 70's are seen in the group of having positive mind for water saving and drinking tap water directly. It is found that gaps between generation and residential area can be deeply related to their attitude and action for water saving and water quality.
