摘要
本文基于遥感和GIS技术,选取1973年至2010年的枯水期MSS、TM、ETM影像为数据源,对江西省信江尾闾(东、西大河)及入湖区域进行了研究.得出1973年至2010年尾闾河道呈现向东北偏移的趋势;湖口的淤积主要发生在主河道左右两侧,并有逐渐向湖内延伸的趋势;冲淤变化受自然因素和人为因素的综合影响.
This paper use the MSS,TM,ETM images in dry time between 1973 and 2010 as source data,which do the research on the two biggest branches of the tail of the Xin River and the Lake Entrance region by GIS and remote sensing technology,the results as followings：we found that the river channel information didn＇t change much,but the river trend to northeast.Through the superposition between 1973 and 2010 the year estuary single band image,we knew that the deposition occurs mainly in the left or right side of the the main channel into the lake area,and to extend in Poyang Lake,gradually have to the main channel concentration trend.Scour and silting variation is influenced by the natural factors and human factors.
