摘要
１９５６—１９９４年唐乃亥流量年变程可分为丰、平、枯和前枯后丰（平）、前丰（平）后枯五种类型，黄河上游主产流区春、夏季（３—５月为春季，６—８月为夏季）平均３．２ｍ地温距平场可分为暖涡、暖涡偏东、暖涡偏西、暖涡减弱消失、均温场和冷涡六种类型。分析发现，地温场型与流量年变程分型之间有较好的相关性。
In this paper,the annual runoff (1956 1994) of upper reaches of Yellow River are classified into five types: rich, normal, poor water years, first poor water then change into rich water(normal) and first rich water(normal) next poor water years The seasonal mean soil temperature fields at 3 2m depths in spring and summer in the runoff source area are classified into warm vortex, warm vortex lies in the east or west, warm vortex decreasing and vanishing, zero deviation field and cold vortex six categories We find that there is good correlation between soil temperature types and annual flow-off cycles,so, we may make qualitatively preliminary prediction of runoff of Tangnaihai reservoir
