Fig. 5

A two-end-member model shows the water mixing in the Changjiang mainstream. Source 1 indicates the contribution from catchment upstream, Yichang and Source 2 indicates the contribution of Dongting and Poyang Lakes in the middle valley. The sub-basins were defined based on different tributary systems and are labeled with a capital letter from A1 to K. Note that the Jinshajiang sub-basin is further divided into two parts (the region upstream Shigu (A1) and downstream Shigu (A2), due to two distinct topography and climate regimes span across the Jinshajiang catchment. The stations for isotopic sampling and meteorological data are likewise indicated in this figure. Refer to Tables 1 and 2 for details of the abbreviations for each station
