| 摘 要： | 基于H J-1号小卫星CCD数据,开展近海水体悬浮物含量监测研究.采用邻近清洁水体和同日MODIS气溶胶产品的方法对CCD辐亮度数据进行较精准的大气校正；利用得到的水体遥感反射率,结合地面准同步实测悬浮物含量数据建立悬浮物反演模型,获得研究区悬浮物的空间分布.模型的相关系数R2为0.849,平均误差为33.0％,反演结果较为理想.结果表明,HJ-1号小卫星作为中国首个灾害监测小卫星星座,能够实现定量反演近海水体的悬浮物含量,对中国近海水体水质的监测和治理具有重要意义.

| Abstract: | On the basis of HJ-1 CCD image, remote sensing detection of suspended sediment concentration in estuary was carried out. A method using clean water nearby and the aerosol product relevant to the moderate resolution imaging spectroradiometer (MODIS) data was adopted to carry out the accurate atmospheric correction. The calculated water reflectance and the measured suspended sediment concentration was used to establish the quantitative retrieval model and get the spatial distribution for suspended sediment concentration in study area. The R2 of this model was 0.849, the mean error was 33.0%, and the result was satisfactory. The study showed that HJ-1 CCD image could be applied to detect the suspended sediment concentration in estuary. |
