摘　　要：白梭梭(Haloxylon persicum)和梭梭(H.ammodendron)是我国干旱荒漠区的优良固沙植物,列入我国第一批保护植物,白梭梭主要分布在新疆北部的古尔班通古特沙漠,梭梭除了分布在新疆外,还分布在青海、甘肃、内蒙古等地,对于它们的生物生态学特性的研究,国内已先后做过不少工作,关于生理方面的研究也有报导。本项工作是从水分生理观点着手。From studying the two species of Haloxylon transpiration and its relations to the environment, it can be seen that the transpirations of the two species are affected by the diffusive resistance, temperature, relative humidity and water potential. The reaction of these are different, the test is shown that the drought resistance of Haloxylon ammodendron is stronger than the that of Haloxylon persicum.
