Dynamic Impacts of Climate and Land-Use Changes on Surface Runoff in the Mountainous Region of the Haihe River Basin, China
The identification of the abrupt change point of runoff in the six mountainous subbasins. The blue and red dots represent the abrupt change point of runoff obtained by a Pettitt test (PT) and moving -test (MTT), respectively. The blue and red lines represent the statistical values obtained by the method of PT and MTT, respectively. The dashed lines represent a significance level of 0.01. (a) is Luan River Basin (LRB), (b) is Chaobai River Basin (CRB), (c) is Yongding River Basin (YRB), (d) is Daqing River Basin (DRB), (e) is Ziya River Basin (ZRB), and (f) is Zhang River Basin (ZhRB).
