摘要
利用PRMS水文模式系统 ,模拟研究了气候变化对滦河流域丰、枯水年不同季节水资源的影响。结果表明 ,滦河流域蒸发量主要受气温变化的影响 ,受降水量变化的影响相对较小 ;且湿润季节变化绝对值较大 ,干旱季节变化百分率较大。而地表径流量、次地表径流量、地下径流量及河川径流量主要受降水量变化的影响 ,受气温变化的影响相对较小。湿润季节对气候变化的敏感性较高 ,干旱季节敏感性较低。
The influence of the climate change on the water resource of the different season in rainy year and drought year over Luanhe river valley was studied by using the precipitation\|runoff modeling system. The results show that the air temperature mostly effect the evaporation of Luanhe river valley. And the influence of precipitation on the evaporation is comparatively less. The change absolute value of evaporation in humid season is greater, and its change percentage in arid season is greater. But the surface runoff, subsurface runoff, ground water and runoff are mostly effected by precipitation. The temperature influence on them is comparative less. And it is more sensitive in humid season than in arid season.
