| 摘 要： | 以华北平原人工杨树林为对象,应用Penman-Monteith、Priestley-Taylor和Hamon模型估算蒸散发量,并以Penman-Monteith模型估算结果为基准,对Priestley-Taylor和Hamon模型进行了修正。结果表明,修正前,Priestley-Taylor和Hamon模型与Penman-Monteith模型的相关系数分别为0.388和0.531,Hamon模型估算的月总蒸散发量结果偏高10.9mm,Priestley-Taylor估算的结果偏低27.3mm;修正后,Priestley-Taylor和Hamon修正公式,相关系数分别提高到0.731和0.761。 |

| Abstract: | Based on the poplars of north China plain,Penman-Monteith,Priestley-Taylor and Hamon model were applicated to estimate forest evaporation.Penman-Monteith model was taken as the benchmark to modify Priestley-Taylor and Hamon models.The results showed that compared with Penman-Monteith model,the correlation coefficients of Priestley-Taylor and Hamon models were 0.388 and 0.531,respectively.The monthly value of Hamon model was 10.9 mm higher than Penman-Monteith model,with Priestley-Taylor model being 27.3 mm less than than Penman-Monteith model.After modified,the correlation coefficients of two models,compared with Penman-Monteith model,were respectively 0.731 and 0.761. |
