| 摘 要： | 根据太湖悬浮颗粒物生物光学特性建立的悬浮颗粒物红外单波段生物光学模型具有明确的机理性.利用2006年至2009年野外实测悬浮颗粒物浓度和水体光学数据对该生物光学模型进行检验和分析.结果表明,悬浮颗粒物比后向散射系数的时空差异是影响总悬浮颗粒物生物光学模型精度的主要因素.总悬浮颗粒物在红外波长的吸收系数对总悬浮颗粒物生物光学模型精度也具有显著的影响.根据中分辨率光谱成像仪(MERIS)悬浮颗粒物 反演结果和野外实测风速数据,太湖沉积物再悬浮将显著增加水体中悬浮颗粒物的含量. |

| Abstract: | The single infrared wavelength bio-optical retrieval model of suspended particle matter concentration (Cmin) based on the bio-optical properties of suspended particle matter in Taihu Lake has specific mechanism. The measured data of suspended particle matter and bio-optical properties during 2006 to 2009 were used to test this bio-optical algorithm. The results indicate that: the spatio-temporal variation of specific backscattering coefficient is the primary influencing factor to the retrieval precision of suspended particle matter. The absorption coefficient of suspended particle matter in the infrared wavelength also have significant effect on the retrieval precision of suspended particle matter. This retrieval model can be successfully apply to the MERIS image data. The resuspended sediment will significantly increase the concentration of suspended particle matter in Taihu Lake according to the MERIS image retrieval result and wind speed monitor data in situ. |
