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。
本文基于遙感和GIS技術，選取1973年至2010年的枯水期MSS、TM、ETM影像為數據源，對江西省信江尾閭（東、西大河）及入湖區域進行瞭研究。得齣1973年至2010年尾閭河道呈現嚮東北偏移的趨勢；湖口的淤積主要髮生在主河道左右兩側，併有逐漸嚮湖內延伸的趨勢；遲淤變化受自然因素和人為因素的綜閤影響。

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 re-sults 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 concentra-tion trend.Scour and silting variation is influenced by the natural factors and human factors.
