摘要
鄱阳湖是一个吞吐型,季节性的浅淡水湖,高水湖相,低水河相。有“高水是湖,低水似河”,“洪水一片,枯水一线”的独特景观。洪涝灾害发生时,给周边地区造成巨大损失。利用TM遥感卫星图片,以特征最明显的1998年特大洪涝灾害为例,对鄱阳湖地区洪涝灾害症结和防洪策略提出几点见解。
Poyang Lake is characterized by in-out and is a seasonable and shadow lake of fresh water. The lake gives a unique prospect that it is like a lake during a rise of water, while like a river during a fall of water; and shows mass during flood, while showing linear during drought.When the flood comes, it does damage to neighbouring area and leads to enormous loss. The article takes an example of the huge flood on the base of adopting the pictures of TM remote sensing satellite. Then, I refer to some proposal on the cause of flood and defending flood.
