The determining techniques of shrub phytomass of four representative xerophytic plant species:Haloxy-lon ammodendron(Mey)Bunge, Caragana microphylla Lam C, korshinskii Kom. and Hedysarum scoparium Fisch;et Mey(Corethrodendron scoparium Basiner et Fischer)have been systematically analyzed and studi-ed.The results showed that traditional sampling method can not be used in determining shrub phytomass incommon practice。Three analytic methods,namely,quantitative,allometric and standard sampling methodsare all ideal for the determination of shrub phytomasses,and among them,the quantitative method is thebest,while the allometric one occupies the second.
