摘要
土地利用和气候变化对流域水循环和水资源的影响已经引起社会的广泛关注。以岷江上游流域为研究对象,以分布式水文模型SWAT(Soil and Water Assessment Tool)为研究工具,建立不同土地利用和气候变化情景,通过模型的校准与验证,模拟不同土地利用和气候变化的径流响应。模拟结果表明随着森林植被面积的减小径流量增大,且裸地增加对径流影响最显著。模拟径流量随着降水的增加而增大,且增加量主要产生于雨季。
Land-use and climate change can influence on basin hydrology cycle and affect water resources what has caused widespread concern in society.We studied on Minjiang upstream watershed,used distributed watershed hydrological model SWAT（Soil and Water Assessment Tool）,established different land-use and climate change scenarios.Based on model calibration and verification,the hydrology response to different land-use and climate change scenarios was simulated.The results indicate the runoff varied with different land-use type,the simulated runoff increased when forestland decreased,and the bareland is the most effective on runoff response.The simulated runoff increased with increased precipitation,and the increased runoff concentrated in summer.
