Abstract

The invention relates to a runoff reconstruction method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a runoff time sequence actually measured by a hydrological station, and acquiring a plurality of Palmer drought index time sequences corresponding to a plurality of positions, wherein the plurality of positions are determined according tothe position of the hydrological station; according to the actually measured runoff time sequence and the plurality of Palmer drought index time sequences, obtaining a substitutability index corresponding to the hydrological station; and inputting the substitutability index corresponding to the hydrological station and the reconstructed runoff time sequence of the hydrological station at the upstream of the hydrological station into a runoff reconstruction model to obtain a reconstructed runoff time sequence corresponding to the hydrological station. Visibly, in the method, on one hand, the Palmer drought index time sequence associated with the position of the hydrological station is adopted, and on the other hand, the upstream and downstream relationship of the hydrological station in thedrainage basin is considered. Since the statistical relationship between the runoff reconstruction related data is considered more meticulously, the accuracy of the reconstructed runoff time sequenceis improved.

Description

technical field [0001] The present application relates to the technical field of water resources treatment, in particular to a runoff reconstruction method, device, computer equipment and storage medium. Background technique [0002] Runoff is an important variable in the water cycle. Long-term hydrological changes and related climate change information are the basis for revealing the long-term evolution of runoff and the development and utilization of river runoff. At present, the monitoring data records of hydrological stations in most regions of the world are relatively short, and the longest historical record of instrumental measurement does not exceed 150 years. Therefore, it is urgent to find a longer historical record of runoff changes. [0003] In traditional technology, tree ring data are often used to extend the time series of river runoff, thus forming dendrohydrology. Dendrohydrology is the science of studying past long-term hydrological phenomena based on tre...
