| 摘 要： | 以黄海及东海海域为对象,研究用MOD IS数据提取我国海域悬浮泥沙时空分布的定量遥感方法,建立了基于MOD IS数据的悬浮泥沙定量遥感实用模式。研究表明,用250 m和1 000 m分辨率的MOD IS数据进行悬浮泥沙浓度的定量遥感,可以达到实际应用的精度要求。这说明,MOD IS数据是研究近岸水体中悬浮物输运变化规律的一种经济实用数据源。

| Abstract: | Suspended sediments constitute an important component of water color,and high concentrations of suspended particulate matter in coastal waters directly affect or control numerous water column and benthic processes.In this paper,the utility of MODIS 250 m and 1 000 m data for analyzing turbid coastal waters was examined in the Yellow Sea and the East China Sea.With a set of processing procedures,the authors used MODIS images in the 250 m model and the 1 000 m model to map the concentrations of suspended sediments.The results were compared with the in-situ data set collected in April 2003.This study demonstrates that the moderately high resolution of MODIS 250 m data is useful in examining the evolutionary process of materials in coastal environments,particularly the smaller water bodies such as bays and estuaries,and that the 1000 m data are perfect in mapping the concentrations of suspended matter in open coastal waters. |
