Abstract: 【Objective】 provide a reference for the selection of salt tolerant perennial herbs for the ecological restoration of salinized soil. 【Method】 Elymusdahuricus,Puccinelliadistans,Agropyron cristatum, Thinopyrumponticum, Gynodondactylon,Bromusinermis,Medicago sativa,Astragalusadsurgents,Onobrychisviciaefolia,Glycrrnhizauralensis,Sophoraalopecuroides,Melilotusofficinalis were treated with NaCl solution 0.0% (CK), 0.5%, 1.0%, 1.5%, 2.0% under salt stress. The daily germination number, root length and bud length of each plant were measured, and the relative germination rate, relative germination index, relative germination potential, relative injury rate and relative root bud ratio were calculated. The membership function formula was used to calculate the salt tolerance score. 【Result】 All kinds of plant seeds were inhibited by salt stress, and the inhibition of each growth index showed a downward trend with the increase of concentration. The final score of salt tolerance of 12 plants was ranked in the following order: Glycyrrhizauralensis>Thinopyrumponticum>Puccinelliadistans>Elymusdahuricus>Sophoraalopecuroides>Agropyroncristatum>Melilotusofficinalis>Medicago sativa >Onobrychisviciaefolia>Bromusinermis>Astragalusadsurgens>Cynodondactylon.. 【Conclusion】 In the second mine ecological restoration area of Danan Lake in Hami,Glycyrrhizauralensis, Thinopyrumponticum, Puccinelliadistans, Puccinelliadistans, Elymusdahuricus, and other perennial herbs be given priority.
