大连地区海岸带灾害地质风险的模糊综合评价

大连地区三面环海，海陆间相互作用非常突出，海岸带上分布着多种类型的灾害地质，在特定的条件下会引发地质灾害，对经济持续的发展、生产生活的安全都带来了极大的威胁．文章运用模糊数学理论将这些不易准确描述的灾害地质因素量化，利用层次分析法结合模糊综合评价方法，对大连地区海岸带灾害地质风险等级做出评定．研究表明大连海岸带灾害地质风险较高，评价结果对海岸带地质灾害的防治工作具有一定的参考意义．

Fuzzy Comprehensive Evaluation of Hazardous Geology of the Coastal Zone of Dalian

Dalian, with coasts on three sides, has very prominent sea-land interaction. There are various hazardous geology on the coastal zone. The specific condition may trigger a geological disaster which is harmful for the economic growth, living and working. The paper make a quantification of the hazardous geology factors that are difficult to describe based on AHP-fuzzy mathematics and evaluate the costal disasters geological risk level intuitively in Dalian area by fuzzy evaluation methodology. The research result showed that Dalian has a higher risk of geological disaster, which is meaningful for guiding the prevention of coastal geological disaster.
