| 摘 要： | 利用阳山县气象观测站1957～2008年阳山县秋季水分蒸发量的气象观测资料,分析了阳山县秋季水分蒸发量的演变规律以及影响蒸发量的气象要素,以此研究蒸发量对阳山县秋旱的影响。结果表明：热力作用对阳山秋季蒸发量影响最大,动力作用次之;气象要素中,对秋季蒸发量影响较大的是平均气温、平均最高气温、平均日较差和日照,风速的影响次之。用气象观测的蒸发量作为实际蒸发量的表征,评估了气候干湿的变化及对当地秋旱的可能影响。运用干燥度,定量地讨论了蒸发量对秋旱的影响。

| Abstract: | By using the evaporate data in autumn in Yangshan County from 1957 to 2008,the characteristics of evaporate in autumn and the factors influencing the evaporate were analyzed,based on which,the influence of evaporate on drought was studied.The results showed that heat had the greatest influence on the evaporate,and power was followed.The average temperature,average maximum temperature,average diurnal temperature range and sunshine greatly influenced the evaporate,than the wind speed.The influence of the change of dry and wet on drought was evaluated using the observed evaporate.The influence of evaporate on drought was discussed using the dryness. |
