Abstract

The invention relates to a water quantity change monitoring method and device, computer equipment and a storage medium. The method includes: acquiring a lake shoreline change sequence, a lake area change sequence and a synthetic height measurement water level sequence; calculating to obtain a lake level sequence according to the synthetic height measurement water level sequence and the lake shoreline change sequence; calculating to obtain a mathematic relation between lake water quantity and water level according to the lake area change sequence and the lake level sequence; calculating to obtain a lake water quantity change sequence according to the obtained lake level sequence and the mathematic relation between lake water quantity and water level. The mathematic relation between lake water quantity and water level is obtained according to the lake area change sequence and the lake level sequence, the lake water quantity change sequence is obtained according to the obtained lake levelsequence and the mathematic relation between lake water quantity and water level, the lake water quantity and water level are obtained through an algorithm, the lake water quantity is obtained according to the lake level sequence, and accordingly accurate remote-sensing monitoring of lake water quantity is realized.

Description

technical field [0001] The present application relates to the technical field of lake water volume monitoring, in particular to a water volume change monitoring method, device, computer equipment and storage medium. Background technique [0002] With the development of remote sensing measurement technology and satellite altimetry technology, the remote sensing monitoring technology of lake water volume changes is also improving. Lakes have natural ecological and social economic benefits such as flood regulation and storage, climate regulation, breeding and irrigation, and tourism development. The water volume change of lakes with less human disturbance can reflect the response of regional hydrological processes to climate change, which has important guiding significance for climate change research. In recent years, the expansion trend of lakes in the Qinghai-Tibet Plateau region is significant, and some infrastructures near the lakeshore, such as roads and transmission line...
