水库一般是中等尺度流域的集水区,且水库底层深入基岩层,利用其无潜流等优势可准确地测得流域河川径流量。文章通过大野口流域气温、降水和流域河川径流18 a (1994-2011)的长期监测与研究,结果表明:(1)大野口流域年均气温、降水量和河川径流分别为1.62℃、374.06 m m和166.7 m m。(2)气温、降水和河川径流均呈波动性上升趋势,气温上升速率约0.023℃灋a-1,降水和河川径流上升速率约1.8mm 灋a-1;降水和河川径流高峰期或低谷期相隔约8a。(3)气温、降水和河川径流在1月最小,平均值分别为-11.91℃、2.74mm和0.32mm ;7月最大,平均值分别为14.38℃、82.48 m m、37.48 m m。
水庫一般是中等呎度流域的集水區,且水庫底層深入基巖層,利用其無潛流等優勢可準確地測得流域河川徑流量。文章通過大野口流域氣溫、降水和流域河川徑流18 a (1994-2011)的長期鑑測與研究,結果錶明:(1)大野口流域年均氣溫、降水量和河川徑流分彆為1.62℃、374.06 m m和166.7 m m。(2)氣溫、降水和河川徑流均呈波動性上升趨勢,氣溫上升速率約0.023℃灋a-1,降水和河川徑流上升速率約1.8mm 灋a-1;降水和河川徑流高峰期或低穀期相隔約8a。(3)氣溫、降水和河川徑流在1月最小,平均值分彆為-11.91℃、2.74mm和0.32mm ;7月最大,平均值分彆為14.38℃、82.48 m m、37.48 m m。

Reservoir generally is medium scale catchments basin ,which bottom goes deep into bedrock layer .There-fore ,it is exactly to measure watershed runoff by taking advantage of its no undercurrent .This study represented a long - termmonitor and research on Dayekou watershed run off temperature ,rainfall and river runoff for 18a (1994-2011) .Results showed that :(1 ) the annual average of temperature ,rainfall and runoff were 1 .62℃ , 374.06mm and 166 .7mm ,respectively ;(2) the temperature ,rainfall and runoff showed a wave rising trend and the rising rate of temperature ,rainfall and runoff were about 0 .023 ℃ · a-1 and 1 .8 mm · a-1 .Intervals of peaks and troughs for rainfall and runoff were 8 a;(3) these three indexes showed the lowest levels in January ,with averages were -11 .91 ℃ ,2 .74 mm and 0 .321 mm ,respectively ;the largest averages appeared in July ,with 14 .38 ℃ ,82.48 mm and 37 .48 mm .
