中文摘要：

内陆水体光学特性复杂，其水质参数遥感反演是当前环境遥感研究的热点与难点．2004年10月在太湖实测了67个站点的遥感反射率与相应站点水质参数浓度，通过对水体反射率光谱的分析发现，秋季太湖悬浮物主导了水体光学特性，叶绿素荧光峰的特征主要体现为悬浮物浓度的变化．据此建立了基于水面实测高光谱遥感反射率数据的叶绿素荧光峰特征与悬浮物浓度之间的拟合关系，发现二者具有很好的响应关系．具体分析了叶绿素荧光峰绝对高度、基线高度、归一化高度（分别归一化到560nm附近最大反射率波段与近红外810nm附近最大反射率波段）及荧光峰积分面积（包括积分总面积、基线以下面积与基线以上面积）等几种光谱特征与悬浮物浓度之间的关系，其相关系数（膏）分别为0．8822、0．7483、0．8901、0．8547、0．8927、0．8877、0．8632，平均相对误差分别为27．25％、41．03％、27．11％、25．75％、24．91％、2547％、27．54％，总体反演精度较高，其中总积分面积法效果最好，基线高度法效果最差，而叶绿素荧光峰波段的位移与悬浮物浓度之间不存在明显的相关性．研究结果表明叶绿素荧光峰特征在浑浊内陆水体悬浮物浓度信息提取中具有很好的应用前景，该方法可为浑浊的二类水体悬浮物遥感反演提供了一个新思路．

英文摘要：

The optical property of inland water is very complex, and inversion of water components concentration of inland water body is hotspot and difficulty problem in water quality remote sensing. The remote sensing reflectance and water qualities of 67 stations were acquired in the Lake Taihu in October, 2004. Basing on the characteristic spectral analysis, it was obvious that the water body spectral character in Lake Taihu in autumn was dominated by the total suspended matter （TSM）. The properties of the chlorophyll fluorescence peak mainly reflect the variation of the concentration of TSM. Hereby, we established the relation between the properties of the chlorophyll fluorescence peak and the concentration of TSM based on in-situ remote sensing reflectance with lnm bandwith and water quality measurements. There were good response relationships between them. Making a concrete analysis of the correlation relationship between the absolute height of fluoresce peak, the height above the reference baseline, the normalized height referred to the maximum reflectance about 560nm in green band and 810nm in infrared band, the integral area （including the total integral area, the integral area between the spectral curve and the reference baseline, the integral area below the reference baseline and the wavelength axis） and the concentration of TSM. Their correlation coefficients were 0.8822, 0.7483, 0.8901, 0.8547, 0.8927, 0.8877 and 0.8632 respectively, and the average relative error were 27.25%, 41.03%, 27. 11 %, 25.75%, 24.91%, 25.47% and 27.54% respectively. The inversion accuracy of the total integral area method is obvious better than the reference baseline height method. No outstanding correlation relationship between chlorophyll concentration and fluorescence peak position were found based on reflectance spectra. The results show that chlorophyll fluorescence properties are effective in detecting TSM concentration in turbid inland water body, which provide a new optional sensitive band to retrieval TSM concentratio
