Abstract:
In order to understand of the dynamical changes and causes of the main lakes over Jiangsu Province to provide the accurate references for flood/drought and water environment control departments in decisionmaking, the dynamical remote sensing of the lakes over the northern Jiangsu Province was conducted by means of the EOS/MODIS satellite dataset in summer of 2005. The threechannel colorized synthetic images are obtained, and the water borderlines of these lakes are extracted with the threshold method. An analysis is made of the area variation of the lakes from the viewpoint of meteorology. It can be seen from the remote sensing images and the statistical results that the areas of the lakes decreased because of the previous drought and then increased because of the subsequent abundant precipitation. The meteorological factors such as sunshine duration, precipitation, etc., have great influence on the areas of lakes.
