【摘要】 基于中国近海海洋综合调查与评价国家908专项(908专项)中关于我国近海海域海水中油类含量数据(2006年7月14日至2007年12月29),据此数据对我国近海海水油类污染现状进行了分析评价。结果显示,各海域油类的测值和平均值除个别站位外,海水中油类均符合一二类国家海水水质标准。就各季油类平均含量高低相对比较而言,冬季>夏季>春季>秋季。就各海域油类平均含量高低相对比较而言,渤海>东海>黄海>南海。部分海域超过了一类标准,如山东半岛以北的北黄海(夏季和冬季)和东沙群岛北部海域(冬季)。更多还原

【Abstract】 This paper got some data which were collected by the special project: National Marine Comprehensive Investigation and Assessment in Offshore China(908).These data(from Jul.14,2006 to Dem.29,2007) involving oil content in seawater in offshore were researched so as to investigate into the pollution situation of China offshore.Results showed that the measured values and the average values of oil content in each sea area were below the standard values of first\second national seawater quality,except those of a few positions,and seawater quality all met the national standards.In terms of seasonal oil content,the sequence was winter>summer>spring>autumn;in terms of average oil content in sea areas,the sequence was the Bohai Sea>the East Sea>the Yellow Sea>the South Sea.The oil contents of some of the sea exceeded the national standards,such as the North Yellow Sea(in summer and winter) and the northern sea waters of the East Sand Island(in winter).更多还原
