Set Pair-Wavelet Analysis on Water Resources Compensation Characteristics of Fu River Basin

摘要

To solve the flood-drought coexistence issue by taking measures on water resources compensation (WRC), the set pair-wavelet analysis method (SPWAM) is proposed to study water resources compensation characteristics (WRCC); and Fu River Basin as a case, the uncertainty correlation and its periodic variation laws, which are implied in synchronous-asynchronous encounter probability of rich-poor rainfall and runoff, are researched; then the traditional methods are used to test the results; the conclusions obtained show that: in Fu River Basin, there is an uncertainty correlation of more synchronous(encounter) probability and little asynchronous(compensation) probability of rich-poor rainfall and runoff or runoff and runoff, and a variation law, which is of characteristics of multiple main cycles, is an alternate change of partial encounter and partial compensation in the correlation. These conclusions can provide better basis and condition to solve the flood-drought coexistence in the basin by adopting measures of WRC regulation and flood resources.
