摘要

In this study, a SWAT model (soil and water assessment tool) was calibrated and validated to analyse the Guishui River Basin, China to simulate the hydrological response to human activities. The parameter sensitivity analysis is processed and the uncertainty analysis is evaluated by SUFI-2 (sequential uncertainty fitting program). The reasonable results indicated that human activities had remarkable effects on runoff. The direct effects influenced runoff much more than indirect effects. The indirect effects increased runoff, especially and dramatically during the flood season. The direct effects decreased the runoff coefficient and more obviously during the flood season. The study finds that urbanisation continues to displace more farmland while in turn farmland encroaches on forests and grassland. The increasingly impervious surface has limited the ability of humans to conserve water in the area. Direct and indirect effects occur through different mechanisms, and direct effects play the most important role in changes runoff rates.
