摘要

The purpuses of this study are to investigate risk perception and decision making of inhabitants against landslide measures in Yokosuka City, Kanagawa Pref. where steep sloping land were developed as residential zone and large number of landslide disasters have been observed around Kanto Area. In order to clarify them, questionary surveys have been implemented to 3,800 householeds. In this survey, firstly information about landslide risk based on past recored disasters in the districts is shown to inhabitants. Secondary alternative measures to clarify the decision making process which led to landslide measures practice every three attributes, below average income, more than average income, and whole respondent by pass analysis. As a result, pass analysis shows that (a) The process to lead to evasion intention in below average income group are different from more than average income group. Especailly risk acceptance is the key factor to decide evasion intention. In below average income group, it means trust to attitude of public sector, on the contrary risk acceptance means zero risk thinking in more than average income group. Inverse correlation is observed between risk acceptance and evasion intention in both groups. (b) Envasion mesures are supposed to be established based on considering differences of the intention to implement evasion mesures and effects of risk acceptance. In both groups, supports of decision making in protection of steep sloping land mesures is essential.(c) It is clarified that making incentives to removal of their housing and casual insurances are required for below average income group, meanwhile expanding present subsidis to control landslide is important for more than average income group with enlightenment not to be zero risk thinking.
