摘要
针对传统的通过水位站点连续观测获取水位信息的方式需要耗费人力、物力和财力的问题,该文提出利用Cryosat-2测高数据对内陆湖泊湖面高变化进行监测,并研究了巢湖水位变化与气候的关系,得出巢湖湖面高季节性变化的规律;同时,与地面水位站实测水位数据进行比较,发现二者存在显著的线性相关性。结果表明,利用Cryosat-2测高数据对内陆湖泊湖面高变化进行监测具有一定的可行性。
Aiming at the problem of height change detection about the surface of inland lake,Cryosat-2was used to detect the height of surface about inland lake,and the relationship between the height of Chaohu Lake and climate were studied;the regularity of seasonal variation of lake's level variation in Chaohu Lake was obtained;there was a significant linear correlation between the height of inland lake and ground water level data.The result showed that the method of using Cryosat-2satellite altimetry data to detect the level variation of inland lake was feasible.
