| 摘 要： | 通过实地测量太湖水体的反射光谱和表层水质,利用实测数据以及水-气界面辐射传输模型计算其遥感反射率,并根据太湖的实际水质状况将其划分为3个区域,分别分析太湖总体和分区的反射光谱曲线,建立太湖不同区域水体悬浮物浓度和透明度的反演模型。结果表明,就悬浮物浓度和透明度而言,太湖3个区域中以东太湖水质最佳,贡湖、梅梁湖和竺山湖次之,南部和西部最差;对太湖进行分区研究能够更好地反应太湖水质的差异性,拟合各区域的水质状况,分区模型精度较全湖区模型高,误差也普遍较小,能够提高研究结果的可信度和可行性。 |

| Abstract: | Field measurement was taken for reflection spectrum of waterbody of Taihu Lake and for water quality of its surface layer.Based on the measurements,a water-air interface radiative transfer model was used to calculate reflectance.According to actual water quality,the lake was divided into three sections.Spectral reflectance curves of the whole lake and the three sections were analyzed and the models for inversion of concentrations of suspended substances and transparencies of these sections was established.R... |
