Abstract: In order to study the effects of climate change on the runoff of the upper reaches of the Tang River, the study used SWAT model and setting up three scenarios, quantitatively analyzes the change of climate change to the runoff of the upper reaches of Tang River, and the results show that:the calibration and validation results of SWAT model indicate that the simulation results meet the requiremrnt of the model.In the period of calibration, ENS is 0.65, R2 is 0.73.In the period of validation, ENS is 0.7, R2 is 0.76,and that the results were good for model.(ii)When precipitation increased by 20% and 10%, the average monthly runoff was increase 7.65m3/s (8.9%) and 4.37m3/s (5.1%). When precipitation was reduced by 20% and 10%, the average monthly runoff decreased by 5.2m3/s (6.1%) and 2.03m3/s (2.4%). When temperatures increased 1℃ and 2℃ respectively, the average monthly runoff in the basin decreased by 0.73m3/s (0.09%) and 2.18m3/s (2.5%), respectively. It shows that the change of runoff and rainfall in the basin are positively correlated with the change of temperature, and the change of temperature is negatively correlated. By predicting the rule of runoff under the future climate scenario of the upper reaches of Tang River basin, we can provide a scientific reference for the policy departments in the rational allocation of water resources in the future.

摘要： 为研究降雨变化对唐河径流的影响，本研究通过构建SWAT模型，设置3种情景方式，定量分析了气候变化对唐河上游流域径流变化情况，结果表明：（1）SWAT模型在唐河上游流域具有较好的适用性，可以通过SWAT模型对该流域进行径流模拟，模型率定期的ENS和R2分别为0.65和0.73，验证期分别为0.7和0.76，满足模型精度要求；（2）降雨量增加20%和10%时，月均径流对应增加了7.65m3/s(8.9%)和4.37m3/s(5.1%)；降雨量减少20%和10%时，月均径流对应减少了5.2m3/s(6.1%)和2.03m3/s(2.4%)，气温分别增加1℃和2℃时，流域月均径流分别减少0.73m3/s(0.09%)和2.18m3/s (2.5%)，表明流域内的径流量变化与降雨量变化呈现正相关关系，与气温变化呈现负相关关系。通过预测唐河上游流域未来气候情景下径流量变化规律，可以给政策部门在未来水资源合理配置等方面提供科学的参考依据。
