中文摘要:

用Penman-Monteith和Priestley-Taylor两种方法分别计算了多伦地区的参考作物蒸发蒸腾量（ET₀），并对该地区的ET₀演变情况进行了分析。经比较，Priestley-Taylor法计算所得ET₀在量值上较大，但用两种方法计算得到的ET₀整体趋势相同，以Penman-Monteith法计算结果为标准从整体上来分析该地区的ET₀变化趋势、特点及其与不同要素之间的相关性，研究发现该地区年ET₀远大于年降雨量；ET₀整体上有微弱的减小趋势，呈现出平稳→增加→减少的过程；风速和日照对该地区ET₀的影响较大。可为当地生产及人类活动调控提供参考。

英文摘要:

The paper used Penman-Monteith equation and Priestley-Taylor equation to calculate the reference evapotranspiration of Duolun，and analyzed the change of ET₀. Through contrast，ET₀ value calculated by Priestley-Taylor equation is larger，but the trend calculated by two methods is almost the same．Using the results calculated by Penman-Monteith method as the standard，the paper analyzed the trend of ET₀ change and features and correlation between ET₀ and different elements．The research showed that yearly ET₀ was far greater than annual rainfall in the area．The ET₀ has a slight decrease trend on the whole，and presents a process of smooth - increase - decrease．Wind speed and sunshine have a larger impact on ET₀．The results may provide some references for agricultural production and human activities．
