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。
In view of the problem that the conventional way of obtaining water level information through continuous observation of water level stations takes human, material and financial resources, this paper proposes to use Cryosat-2 altimetry data to monitor the high change of lake water level in inland lakes, Climate, and draw the law of the seasonal changes of the lake in Chaohu Lake. At the same time, compared with the measured water level data of ground water level stations, we found that there is a significant linear correlation between the two. The results show that using the Cryosat-2 altimetry data to monitor the lake surface inland lakes is very feasible.
