• Through monitoring the growth of wetland plants mainly common reed and cattails and assaying o g and tph in soils according to time ? ? lapse , the function of wetland degrading oil pollution was validated . the petroleum pollutants in the surface layer of soil were decreased by eluviations and degradation
  通过监测湿地植物芦苇香蒲等的长势和化验土壤中总石油烃tph及油和脂o g随时间的变化，以探讨湿地状态对石油污染和植物长势的影响。
• It is shown that the combination of the two simple analytical techniques remedies the shortage of the single one , and that the combination is successfully used to monitor the biodegradation efficiency of diesel and its primary components , and to evaluate separately the degradation of linear alkanes and aromatic hydrocarbons components
  研究结果表明，这两种简单方法的简单组合，弥补了单一方法的局限性，能够监测石油烃类污染物总体和主要组分的降解程度，实现对烷烃和芳香烃降解的分别评价。
• However , except nitrate , the nitrogen concentration including nitrite , ammonia , don , pn and tn in spring 1998 were higher than those in autumn 1997 , with the average concentration of 4 . 9714 . 65 , 0 . 67 ? . 20 , 0 . 7210 . 30 , 9 . 2516 . 88 , 7 . 3014 . 42 and 22 . 9 ? 0 . 2 mol / dm3 in autumn , and 4 . 5812 . 39 , 0 . 70 + 0 . 14 , 2 . 2611 . 05 , 9 . 8814 . 92 , 7 . 8816 . 21 and 25 . 318 . 94 mol / dm3 in spring , respectively . the n / p ratio in autumn 1997 was 13 . 217 . 54 in average which a little lower than redfield ratio , nevertheless in spring 1998 the value was as high as 25 . 6113 . 0 , much hi gher than redfield ratio . there shows a clear seasonal variation of phosphorus structure in two seasons , but the nitrogen structure almost unchanged
  两个季节海水中磷的结构变化明显，秋季磷主要以pp ( 54 )为主，而春季长江口营养盐、石油烃对海洋生态系统影响及动力学研究主要以po4一p ( 51 % )为主;两季节氮的结构基本一致，溶解氮都以don为主，分别为40 %和39 % :秋季no3一n比例较春季略高( 22 % ) ，而春季nh4一n比例较秋季略高( 9 % ) 。
• Aimed at the hot point of the marine environmental ecosystem , the distribution and variation of nutrients and petroleum hydrocarbon , controlling mechanism and the influence to marine ecosystem were conducted in this thesis , according to the 2 cruise of field survey in the changjiang estuary and adjacent area , in suit mesocosm experiment and the dynamic model of ecosystem as well . the research would give some necessary scientific foundation to the research work for mechanism of the red tide in east china sea
  本文针对这一海洋生态环境的热点问题，通过对长江口邻近海域的海上现场调查、现场围隔生态实验以及相关生态动力学模型研究，对该海域营养盐及石油烃污染物的分布变化规律、控制过程以及对海洋生态系统的影响进行了研究，以为东海赤潮发生机理研究提供必要的科学基础。
