| Abstract: | Digital identification of oil fingerprints based on the mathematic statistics method plays an important role on rapid, accurate and automate identification of oil spill. The principle and method of repeatability limit, clustering analysis and t-test methods on oil spill identification in coastal zone were analyzed in this paper. Taking the Dalian oil pipeline explosion as a typical case, the common diagnostic ratios of oil spill identification were evaluated and selected by the repeatability limit comparison method. Moreover, sources of the oil pollutants in Jishatan and Haibei Square of Dalian were also identified by using clustering analysis and t-test method. |
