Evaluating ecohydrological driving factors controlling the hydrology of the Wuijang River Basin, China

Abstract River hydrology is an important proxy for changes in river runoff and factor affecting the ecology of rivers. To quantitatively evaluate Wuijang basin, this paper uses various tests to analyze runoff. The IHA-RVA method combined with FDC ecohydrological indicators was used basin calculate contribution human activities climate change results show that (1) Wujiang has shown a decreasing trend over years, sudden 2005 mainly two inter-annual cycles; (2) overall hydrological 48%, which moderate change; (3) ecological are significantly correlated rainfall, correlation between IHA strong; (4) main influencing factors River. have some reference value management improvement restoration ecology.
