摘　　要：应用SWAT模型对香溪河流域的径流过程进行了模拟,用相关系数R2和Nash-Suttclife模拟系数(Ens)对其模拟效果进行了评价,旨在揭示气候变化和土地利用变化对香溪河流域径流的影响。结果表明,香溪河流域因土地利用变化引起的径流深变化率为26%,而由气候变化引起的径流深变化率为62%,表明近20年来香溪河流域径流的变化主要由气候变化所造成。In order to study the influence of change in both climate and land use on runoff, the process of runoff of Xiangxi river basin was simulated by applying SWAT model, and the simulating effect was evaluated using the correlation coefficient R^2 and Nash - Suttclife. The study results showed that 26 % of the total runoff change was caused by the change of land use, and 62 % was caused by the change of climate, which implied that climate change was the main driving factor for runoff of this area.
