    摘要:

    基于1996—2010年枯水期6幅TM遥感影像数据和2010年、2015年典型断面测量数据,从不同尺度对鄱阳湖入江水道区冲淤变化规律进行研究。结果表明:入江水道主槽总体表现稳定,不存在游荡现象;入江水道主槽总体表现为冲刷,年冲刷速率为0.01m;濂溪区朱家村以北河段、星子水文站断面附近因受人类活动较少,主槽岸线未发生显著变化,表征为冲刷集中区,年冲刷速率分别达0.08m、0.04m;濂溪区至庐山市老虎垄之间河段、庐山市陶子发河段在2000—2010年间受人类活动影响显著,在2010年后人类活动影响显著减弱情况下分别表征为冲淤平衡区和淤积区。

    Abstract:

    The law of scouring and silting in the waterway of Poyang Lake to Yangtze River was studied from different scales based on 6 TM remote sensing image data in the dry season from 1996 to 2010 and typical cross-section survey data in 2010 and 2015. The results showed that: The main channel for the waterway of Poyang Lake to Yangtze River was stable without wandering phenomenon and it was scoured with 0.01m annual scours rate; Due to less human activities, the main channel shoreline near the north section of Zhujiahe village in Lianxi District and Xingzi hydrological station section has not changed significantly, characterized by erosion concentrated area with 0.08m and 0.04m annual scour rate, respectively; The river section between Lianxi and Laohu ridge in Lushan City, and Taozifa river section in Lushan City were marked by human activities from 2000 to 2010, while the impact of human activities was significantly reduced after 2010 and it was characterized by erosion and deposition balance area and silting area.
