| 摘 要： | 根据郑州地区1980—2000年的气象资料,应用Penman-Monteith公式计算21 a间参考作物腾发量ET0,分析了ET0的月际变化和年际变化特征.结果表明,ET0值呈现为逐年减少趋势,说明气候变化对ET0的影响较大;并分析了各气象要素与ET0的相关性,在郑州地区ET0与平均相对湿度相关性最好.

| Abstract: | Based on the meteorological data collected from 1980 to 2000 in Zhengzhou,the reference crop evapotranspiration(ET0) is calculated with the Penman-Monteith equation recommended.The monthly and annual change characteristics of ET0 are analyzed.The results show that ET0 values were decreasing year by year,which shows that the impacts of climate change on ET0 are great.The correlations of every key element of weather,with ET0 are analyzed.The coefficient of correlation of ET0 with average relative humidity was the best. |
