基于年尺度的新疆车尔臣河流域各气象要素对水面蒸发影响分析

Study on impact degree of meteorological factor to water evaporation in Che'erchen River Basin based on annual-scale

根据新疆且末县气象站多年平均水面蒸发量及相关常规气象观测资料,利用灰色关联度法分析各气象要素对水面蒸发的影响程度。结果表明各气象要素对年均水面蒸发量的影响程度从大到小的排列顺序为日照时数>风速>气压>气温>总云量>相对湿度>水汽压。从气象因素角度出发,为区域水资源优化调度提供参考。

Based on Qiemo County meteorological station from 1953 to 2008, the evaporations by small pan and related conventional meteorology observation information, analyzed the influence of each meteorological factor to the evaporation of small pan by using the gray relation analysis, the results have shown the impact degree of each meteorological factor to evapora- tion by small pan, the arrange order from large to small is sunshine hours 〉 Wind 〉 Pressure 〉 temperature 〉 total cloud amount 〉 relative humidity 〉 vapor pressure. Hoping from the meteorological factor, supply the theoretical reference for the optimal distribution of the water resources in local region
