Changes in Homogeneous degree Caused by Marine Oil Spill

Based on the survey data of Jiaozhou Bay waters in May, September and October 1993, this paper studies surface horizontal distribution PHC content waters. According to definition, model classification Yang Dongfang homogeneity theory matter proposed by author, calculation results show that Bay, non-homogeneous column was 46.86μg/L, 8.15%. At time, had non-homogeneity; September, 6.53μg/L, homogeneous 48.58%, which a low degree homogeneity; October, 0.40μg/L, 96.61%, high homogeneity. This shows entire there only source marine oil spill transportation, transported 51.00μg/L, relatively high, resulting unevenly distributed water body bay. In its 12.70μg/L, low. way, lowly homogeneous. no bay, highly From May monthly decline rate from 9.57μg/L, 10.08μg/L, increase 10.10%. 6.13μg/L, 48.03%. fully reveals is driving force non-homogeneity area, while ocean tides currents are area. this, author puts forward material content: under action currents, has characteristics homogeneity,
