在这项研究中，我们开发了一个影响因子公式（IFF），以定量地分别归因于气候变化和当地人类活动对黄河子流域的水文响应（即径流）的影响，在1950-2000年。利用逐日气候资料，首次将变入渗能力（维克）水文模型校正和验证到基线期1955-1970年。然后，我们使用维克模型开发了该流域接下来三十年（1971-2000年）的自然径流，而不考虑当地人类的影响，因为维克模型是以20世纪60年代的水文状况为基准的。
In this study we developed an impact factor formula (IFF) to quantitatively attribute separately the impacts of climate change and local human activities on hydrological response (i.e. run‐off) in a sub‐basin of Yellow River for the period 1950–2000. Using the daily climatic data, we first calibrated and verified the variable infiltration capacity (VIC) hydrological model to the baseline period 1955–1970. Then we developed the basin's natural run‐off for the following three decades (1971–2000) using the VIC model without considering local human impacts, as the VIC model is benchmarked by the 1960's hydrological regime.
