摘要
根据三门峡库区长时间序列气象观测数据,采用FAO推荐的标准化Penman-Monteith公式,对库区湿地优势种群芦苇的实际蒸散量ETc进行了估算,分析了芦苇湿地蒸散量的年内和年际变化规律,并对影响芦苇湿地实际蒸散量的主要环境因子进行分析。结果表明:夏季三门峡库区芦苇湿地的实际蒸散量较大,冬季较小,在6月达到年度最高值,为190.17 mm;库区多年平均(1957—2010年)芦苇湿地实际蒸散量为1 056.59 mm,54 a中最高为1 278.23 mm(1959年),最低为818.05 mm(1984年);库区湿地ETc与各环境因子之间存在多元线性回归关系。
Based on long-term meteorological scenarios of weather stations,the FAO Penman-Monteith formula was applied to estimate the actual evapotranspiration（ETc） of reed in the Sanmmenxia Reservoir area.The annual and interannual variations of evapotranspiration were analyzed,furthermore,the influential key environmental factors were specified.The results show that a）on the annual variation,the averaged monthly maximum value is 190.17mm which is in June;b）on the interannual variation,the mean value is 1 056.59 mm,the maximum is in 1959 and the minimum is in 1984 which are 1 278.23mm and 818.05mm,respectively,based on the data of 1957-2010;c） the multiple linear regression relationships between evapotranspiration and environmental factors are conducted.
