摘要
在开展福州城市地质灾害隐患区调查与成灾机理研究的基础上,通过分析闽江口地区地质灾害分布特征与影响因素,采用层次分析法建立地质灾害危险性评价指标体系,构建层次结构模型,并通过建立判断矩阵,计算各评价因子的权重,结合该地区的实际情况,运用加权叠加法计算出危险性综合指数。最后进行了危险性区划研究,并且对不同危险性级别的区域提出防治建议,为该地区的地质灾害防治决策及群测群防提供科学依据。
Based on the project of investigation and mechanism study of geological hazard,by analyzing the distribution characteristics and influence factors of geological hazard in min river area,this paper builds the risk assessment of geological hazard system by AHP,and calculates the weight of each evaluation factor by constructing judgment matrix.Then calculates risk index using the weighted stack,combining with the actual situation in the region.At last,this paper researches hazard zonation and provides scientific reference for geological hazard prevention and mass prediction.
