摘要

遥感技术是目前获得河口地区及近海水域泥沙分布与扩散的有效方法,多采用美国Landsat系列的多光谱扫描仪(MSS)和专题制图仪(TM)、NOAA气象卫星、法国SPOT卫星资料和前苏联的联盟号以及我国的国土卫星资料等,即将发射的美国海洋卫星将为本项研究提供新的途径。资料的形式有磁带(CCT)和卫片两种,目前世界上以陆地卫星资料应用最广,这主要是由于它有资料商业化、易于获得、资料系列长、重复周期短、可监测动态変化及影像分辨率适中(MSS像元空间分辨率为80m,TM为30m)等优点。河口区泥沙受河流径流、潮流、风浪等多种动力因素影响,悬浮泥沙的含量和颗粒组成经常变化,因而河口悬沙的时空分布及其运动规律较为复杂,用常规测量方法难以了解其变化规律,而遥感的多时相、多波段可监视泥沙扩散的动态变化;同时,陆地卫星图象覆盖面积较广(185×185k㎡),不同图幅的拼接、镶嵌技术也已完善,故可监测河口区泥沙扩散的空间变化。因此,遥感技术弥补了常规手段的费时、耗资、资料不同步、周期长、难以反映多变的黄河泥沙的动态变化等不足。本文根据1989年8月黄河口海区表层泥沙实测资料与天气条件大致相同的遥感资料(磁带)进行了相关分析,定量研究黄河泥沙入海后的扩散和分布规律。

Abstract

A relative analysis of suspended matter concentration of sea surface water sampled in Aug. 1989 from the Huanghe River Estuary area and of Landsat Tape Data taken under the weather condition similar to those during the period of sampling was made.The best band (TM3) or bands (TM3 and TM4) for the study of suspended matter and a relative regression or divided regression formulae were obtained. A simple method eliminating the atmospheric disturbance was proposed after analyzing the optic features of Landsat tapes. The error and its cause in the quantitative model was discussed as well.
