黄淮洪泛作用控制因素及对京九铁路威胁的遥感分析

据遥感影像揭示,除气象因素外,黄河与淮河洪泛形成主要受近代和现代活动构造控制。据分析,黄河下游现行河道存在一定程度隐患,部分河道稳定性较差,淮河中上游地区是现代沉降区,洪水壅滞难泻,对京九铁路及黄淮下游人民生命财产构成威胁

ANALYSING THE THREATS OF THE FLOOD OVERFLOWING FROM THE YELLOW RIVER AND THE HUAIHE RIVER TO JINGJIU RAILWAY USING REMOTE SENSING DATA

According to remote sensing information from Landsat and NOAA images, besides the meteorological factor, the flooding and waterlogging of the Yellow River and the Huaihe River are mainly controlled by modern activity tectonic. There are some hidden dangers in the lower reaches of thr Yellow River for the current river course and the river banks lack of stability. The flood overflowing from the upper to middle reaches of the Huaihe River is difficult to drain off because this area located in a modern depression. This situation constitutes a threat to some extent to Beijing-Jiulong Railway and the people living in the lower reaches of those two rivers.
