Abstract:: The dissertation chose Patycladusorientalis,Larixprinapiam-rupprechtii,Pinus tabulae formis,Populus bolleana,Ailanthusaltissima,Zizyphus jujube,Ulmus pumila and Juglans regia on the Loess Plateau to be our subjects.In July of 2006,we had their transpiration rate and other factors.The results show:in one day,the decreasing orders of average transpiration rate of the eight tree species is Populus bolleanaAilanthus altissimaLarix prinapiam-rupprechtiiPatycladus orientalisUlmus pumilaPinus tabulae formisJ uglans regiaZizyphus jujube.But the decreasing orders of average daily evapotranspiration is Populus bolleanaPatycladus orientalisAilanthus altissimaLarix prinapiam-rupprechtiiPinus tabulaeformisJuglans regiaZizyphus jujubeUlmus pumila.So we can see that the average transpiration rate and the average daily evapotranspiration of the eight tree species is not consistent,when the former was high,the later maybe very low,just so so.The results also show that the Populus bolleana and the Ailanthu saltissima consume more water than other species,Patycladus orientalis,Larix prinapiam-rupprechtii and Pinus tabulaeformis consume lower water,the Ulmus pumila,Zizyphus jujube and Juglans regia don’t consume lots of water and have economic benefit to local people,so they are precede to other tree species.
