| Abstract: | Based on the daily observation meteorological data on mosuowai、paotai、shihezi and wulanwusu weather station,daily reference crop evapotranspiration were calculated and compared by Penman-Monteith、Hargreaves,Priestley-Taylor methods from SWAT2000.Results showed that the result of Hargreaves is greater than Penman-Monteith and Priestley-Taylor is less than Penman-Monteith on mosuowai and paotai.Hargreaves is less than Penman-Monteith and Priestley-Taylor is close to Penman-Monteith on shihezi and wulanwusu.Hargreaves is no significant difference with Penman-Monteith by t-test on paotai,thus can substitute Hargreaves for Penman-Monteith;Priestley-Taylor is no significant difference with Penman-Monteith on mosuowai,shihezi and wulanwusu,can substitute Priestley-Taylor for Penman-Monteith.Three methods calculating reference crop evapotranspiration were remarkable relativity with evaporation,correlation coefficient were greater than 0.95 and can estimate ET0 by evaporation using regression formula. |
