摘要
采用GIS方法，对南沙群岛海区海底灾害地质进行空间叠加分析。利用模糊数学方法，对不同灾害地质因素赋予不同的模糊影响权值；运用模糊叠加模型，得到南沙群岛海区海底灾害地质综合评价图。与前人的研究工作进行对比的结果表明，GIS方法是进行海底灾害地质评价的一种有效方法。
Due to the difficulties in collecting seafloor data, the former researches on thesubmarine geological disasters in the Nansha Islands sea area are mainly based on activefaults, the other potential elements may be ignored. An approaching model may bereached by GIS method which can synthesize many factors affecting submarine environ-ment. Giving appropriate values to the different influencing layers and using fuzzy algo-rithm spatial analysis, a GISaided submarine geological disaster assessment method isproposed in this paper, which is proved to be a good way in geo1ogical disaster evalua-tion compared with the former research method.
