摘要： 为了进一步揭示本溪山区蒸发量和降水量变化特征，利用本溪市草河口气象站1953—2010年的气候资料，运用统计分析、山本检测、小波分析等方法，对蒸发量与降水量的年代际变化趋势、突变进行检测和周期分析。结果表明：年蒸发量呈显著的增加趋势变化，其线性倾向率为25.64 mm/10 a；四季蒸发量也呈增加趋势变化。降水为不显著减少趋势变化，其速率为-30.64 mm/10 a，春季为显著增加趋势，秋季为显著减少趋势，夏季和冬季为不显著减少趋势变化。蒸发量与降水量具有非常显著的相关性；降水量减少速度略大于蒸发量，加快了本溪山区气候变干的趋势。

Abstract: In order to reveal variation characteristics of evaporation and precipitation in Benxi mountainous area, based on the climate data of weather station in Caohekou, Benxi from 1953 to 2010, using statistical analysis, Yamamoto detection, wavelet analysis method of evaporation and precipitation decadal trend, mutation detection and cycle analysis. The results showed that: annual evaporation showed a significant increasing trend, its linear trend rate 25.64 mm/10 a; seasons evaporation also showed an increasing trend. Precipitation did not significantly reduce the trend, its rate -30.64 mm/10 a, spring for a significant increasing trend in significant decreasing trend in autumn, summer and winter was not significantly reduce the trend change. Evaporation and precipitation had a very significant correlation; the precipitation decreased speed was slightly larger than the evaporation speed up climate dries trend in Benxi mountainous area.
