基于多源卫星数据的高邮湖长时序水位变化监测
Long time series monitoring of water level change in Gaoyou Lake based on multi-source satellite data
摘要
Abstract
Lake water level change is one of the most crucial indicators of lake change.Monitoring this change can provide a ba-sis for efficient development and use of water resources and water resource scheduling in river basins.Taking Gaoyou Lake as the research object,the water level sequence from 1993 to 2021 was constructed using T/P satellite and Jason-1/2/3 satellite altim-eter data.Moreover,M-K mutation test and sliding t test were adopted to discuss the characteristics and influencing factors of wa-ter level change in Gaoyou Lake combined with meteorological and social statistical data.The results show that with a comprehen-sive use of the T/P-Jason1/2/3 series satellites,it is possible to monitor Gaoyou Lake's water level for a long time,with a 20 cm accuracy.Based on the long-term data,Gaoyou Lake's water level suddenly changed in 1997.In 2003,the annual average water level reached its peak,and the water level reached its peak in many years from July to October.The annual distribution was uni-modal.关键词
