利用黄河月水文模型 ,采取假定的气候方案 ,分析了中上游径流量对气候变化的响应。结果表明 ,径流量对降水变化的响应较气温更为显著 ,气温不变 ,降水增加 10 %的情况下 ,中上游径流量约增加 17% ;降水不变 ,气温升高 1℃ ,径流减少 5 %左右 ;在区域分布上 ,中游较上游对气候变化敏感
Using the monthly hydrological model of the Yellow River, a hypothetical climate scenario was taken to analyze the response of upstream and midstream runoff to climate change. The results showed that the response of runoff to precipitation was more pronounced than that of air temperature, and the temperature was not changed. When the precipitation increased by 10%, the runoff in the middle and upper reaches increased by 17%, while the precipitation did not change, the temperature increased by 1 ℃ and the runoff decreased by 5% %; In the regional distribution, the upper reaches of the upper reaches of the climate change-sensitive
