摘　　要：以黄壁庄水库为试验区,利用ASD手持式光谱辐射计进行了库区水体反射光谱测量和同步水质采样分析,在分析水库水体反射光谱特征的基础上,运用微分光谱技术和统计相关方法直接分析诊断悬浮物浓度(SS)的敏感波段,并建立简单的线性估算模型.结果显示,715nm波段反射率的一阶微分与悬浮物浓度有较好的相关性,为今后利用星载高光谱传感器对黄壁庄水库乃至我国北方内陆水体悬浮物浓度进行大面积反演提供理论基础.In order to determine the concentrations of suspended sediments using remote sensing, field hyperspectral data and water samples were collected in Huangbizhuang Reservoir in Shijiazhuang City. On the basis of analyzing the reservoir water reflectance spectral characteristics, the sensitive band of water quality parameters was diagnosed with the methods of differential spectroscopy and statistical analysis, and simple linear models to estimate were established. The result shows that the 715nm was regarded as the best detecting region for the content of SS. It provides the theoretical basis for the future study of large-area water quality parameters anti-speech in Huangbizhuang Reservoir and even inland body of water in northern China.
