项目摘要

A marine environmental issue has around urbanized area become a serious problem in recent years. The severe confliction of opinion between protection and development for environment come to the surface in every environmental preserved area. But it is difficult to evaluate practically some benefits for human from the environment system such as the risk reduction to natural disaster and the development to natural resources. Therefore it has been important to estimate the value and the effects of mitigation for natural environment by the risk analysis.In this paper, the CVM (contingent valuation method) is applied to the estimation of value of environment. And some extent of influence factor for the value of environment is analyzed by Quadratic theory 1. Furthermore intensity of relationship between factors for the value of environment are analyzed by method of tally cross table. Finally the evaluation model for environmental value is constructed through the cumulation of these statistical methods.The effect of proposal evaluation model in this context is verified through below applications; 1)the environmental problem caused by the construction of Island city in Fukuoka bay, 2)concerned action for mitigation of the moat environment by the residence in Yanagawa city, 3)the biological hazard at marine environment caused by ballast water exchanges.

近年来，城市化地区的海洋环境问题已经成为一个严重的问题。环境保护与发展之间的严重矛盾在各环境保护区日益凸显。但是，环境系统给人类带来的一些效益，如减少自然灾害风险、开发自然资源等，却很难在实际中进行评估。本文将条件价值法（CVM）应用于环境价值的评估中，通过对环境价值的风险分析，对环境价值进行评估。并运用二次型理论分析了环境价值的影响因素。并利用理货交叉表法分析了各因素对环境价值的关联度。最后通过这些统计方法的累积构建了环境价值评估模型，并通过以下应用验证了该模型在此背景下的应用效果; 1）福冈湾岛城建设引起的环境问题，2）柳川市住宅为缓解护城河环境而采取的行动，3）压载水交换对海洋环境的生物危害。
