| 中文摘要: |
| 采用气候趋势系数和气候倾向率方法，分析了内蒙古自治区境内26个常规气象观测站1959～2008年的20 cm口径蒸发皿蒸发量观测资料。结果表明，区域年、季平均蒸发皿蒸发量变化都呈下降趋势；但站点蒸发量与整个区域的蒸发量变化趋势并不完全一致，存在波动，在大部分站点年蒸发量变化趋势中则是春、夏两季的蒸发量变化趋势占主导地位；蒸发皿蒸发量变化趋势由气象因子综合作用，“蒸发悖论”不适合用来描述黄河内蒙古段蒸发皿蒸发量的变化特点。 |

| The variation of 20 cm pan evaporation in Inner Mongolia in the Yellow River Basin was analyzed based on 20 cm pan evaporation data of 26 weather stations from 1959～2008 by using the method of climate tendency coefficient and climatic trend rate. The results showed that the average annual and average seasonal pan evaporation declined. But the variation of annual evaporation sequences of 26 weather stations was not completely consistent with average pan evaporation of the whole region, it was in fluctuation, and in which spring and summer were the majors. The meteorological elements had different performance in pan evaporation of different regions, “pan evaporation paradox” was not absolutely correct. |
