摘要
根据2008年5月和2009年8月在辽宁省盘锦市石油类污染水体配比试验和现场试验获取的光学特性数据及生物化学特性数据, 分析了石油类含量和后向散射系数数据的关系。 结果表明: 河口区的后向散射系数幂律指数遵循随着悬浮物浓度增加而减小的对数变化规律; 440~856 nm波长范围内单位后向散射系数在0.006~0.035 m2g-1之间, 并且随波长增加而减小; 石油类含量对后向散射系数的影响集中反映在石油类单位后向散射系数(单位石油类含量的后向散射系数)上, 石油类单位后向散射系数与石油类含量呈乘幂变化规律, 且随波长的增加而减小; 石油类含量对后向散射系数幂律指数影响小。
Abstract
The petroleum pollutants mixing proportion experiment and in-situ experiment were carried out in the estuary of Panjin, Liaoning province in May 2008 and August 2009. The optical properties and biochemical properties were measured to get the effect of petroleum concentration in water on backscattering coefficients spectrum. The results show that the power-law index of backscattering coefficient decreases as TSM concentration increases and the relationship of these variables follows logarithm mode. Specific backscattering coefficient’s value of 440 to 856 nm is between 0.006 and 0.035 m2·g-1 and decreases as wavelength increases. The petroleum mass-specific backscattering coefficients (backscattering coefficients of unit petroleum concentration) decreases with the wavelength increasing and follows power law for petroleum concentration. Petroleum concentration has little effect on the power-law index of backscattering coefficient.
