中国海域灾害地质区划初步探讨
A preliminary study for hazard geology divisions in China Sea areas
摘要
Abstract
Based on the results of existing research data analysis and understanding,this article explores division principles of marine hazard geology and it is the first time for hazard geology divisions of whole China Sea areas.According to the boundaries of large tectonic geomorphology it can be divided into 4 hazard geology regions,i.e.coastal,continental shelf,continental slope,basin and trough hazard geology regions.According to geographical location and hazard geology environmental features it can be divided into 24 hazard geology sub-regions.In addition,based on the hazard factor and disaster pregnant environment the geological hazard risk level in China Waters is qualitatively divided into 4.In 24 hazard geology sub-regions which accounted for 11 higher risk,about nearly half of the total,followed by 7 lower risk,nearly one-third of the total,and high-risk and low-risk sub-regions were only 4 and 2 respectively.关键词
