| 摘 要： | 根据夏季青藏高原热源变化与黄河上游流量密切相关的统计事实，用一个大气环流模式（GCM）进行了夏季青藏高原热源强度变化对径流影响的数值试验。结果表明，高原热源减弱则径流减少，流量也随之下降。可见，夏季高原热源变化是导致高原地区乃至黄河上游流量变化的重要原因之一。

| Abstract: | Based on statistical facts,the heat source variation of the Qinghai-Xizang Plateau is relatedwith the flow of upper reaches of Yellow River.A numerical experiment of influence of the heatsource variation over the Qinghai-Xizang Plateau on the flow of upper reaches of Yellow River inthe summer is performed with a moded of GCM.The results show that while the heat source of thePlateau is weaken,the runoff is decreased and flow is descended.As a result,the heat source vaia-tion of the Qinghai-Xizang Plateau is one of the important causes which led to flow variation ofthe upper reaches of Yellow River. |
