The East Eurasi.n Steppe Transect （EEST） i. the i.rst i.ternati.nal transect across regi.ns of mi.dle and hi.h lati.udes i. the eastern Eurasi.n steppe. The EEST i. an i.eal platform for researchi.g the response of Eurasi.n temperate steppe to global change, because of i.s i.tegrated gradi.nts of temperature and human acti.i.i.s on a large-scale. i. thi. study, basi. characteri.ti.s of plant communi.i.s along the EEST across a lati.udi.al gradi.nt was analyzed. Accordi.g to the survey of 58 sampli.g si.es, there are 140 speci.s belongi.g to 34 fami.i.s and 94 genera. Of parti.ular note was the i.ndi.g of Astragalus dalai.nsi. whi.h has di.appeared i. the grasslands of Chi.a. On the whole, Grami.eae plants are domi.ant wi.h Li.i.ceae plants i. the communi.i.s si.ni.fcantly decreasi.g along the lati.udi.al gradi.nt from south to north. The Shannon-Wi.ner i.dex and bi.mass of communi.i.s all decreased along the lati.udi.al gradi.nt wi.h si.ni.fcant negati.e li.ear regressi.ns. The SDR2 （summed domi.ance rati. based on two factors） of domi.ant plants i. the upper layers of communi.i.s, such as Sti.a and Leymus chi.ensi., decreased along the lati.udi.al gradi.nt from south to north. Especi.lly, the SDR2 of L. chi.ensi. decreased si.ni.fcantly. The SDR2 of Clei.togenes squarrosa, Agropyron cri.tatum i. the lower layers of communi.i.s and the i.di.ator speci.s for degradati.n were not affected. Potenti.la acauli. was found mai.ly i. the southern and northern areas.

Grazi.g can dramati.ally affect ari. grassland communi.i.s that are very vulnerable to envi.onmental changes due to i.s relati.ely short and sparse ground coverage, low bi.mass, sandy soi. and i.ter-annual preci.i.ati.n found i. the desert steppe. The study i.vesti.ates the effects of di.ferent grazi.g durati.ns on vegetati.n and soi. properti.s of a desert steppe communi.y. The experi.ent was conducted i. Xi.u Banner i. i.ner Mongoli. wi.h i.ve treatments：CG （conti.uous grazi.g）, 40UG （40 d ungrazed）, 50UG （50 d ungrazed）, 60UG （60 d ungrazed） and UG （ungrazed）. The bi.mass of both shrub and annual-bi.nni.l plant communi.i.s were si.ni.fcantly decreased by CG. Conti.uous grazi.g and 40UG si.ni.fcantly reduced the ANPP （aboveground net pri.ary producti.i.y） by the end of the three year study. 60UG treatment i.creased soi. organi. carbon （OC）, total ni.rogen concentrati.n （TN） and total phosphorus concentrati.n （TP） concentrati.ns and 50UG i.creased the TN and total phosphorus concentrati.n （TK） concentrati.ns, whereas CG, 40UG and 50UG decreased soi. OC, TP and avai.able phosphorus concentrati.n （AP） concentrati.ns. The perenni.l plant speci.s of the desert steppe were generally tolerant for grazi.g. The annual-bi.nni.l plant speci.s had large vari.bi.i.y i. ANPP because of the i.ter-annual preci.i.ati.n. Our results hi.hli.ht that i.ter-annual preci.i.ati.n vari.ti.ns could strongly modi.y the communi.y responses to grazi.g i. ari. ecosystems.

Understandi.g how the growth of two key nati.e grass speci.s of the Northern Great Plai.s （Western wheatgrass and blue grama） may be affected under drought and ni.rogen defi.i.ncy i. essenti.l for future management of these grasslands. The random complete block experi.ental desi.n greenhouse study exami.ed the effects of water and N addi.i.n on above-ground and below-ground harvested bi.mass of C3 （Western wheatgrass, WWG） and C4 （blue grama, BG） grass speci.s for the purpose of gai.i.g better understandi.g of drought responses for these two speci.s. Compared wi.h well-watered treatment （fi.ld capaci.y）, two water li.i.ed treatments （70% and 85% fi.ld capaci.y） decreased plant above- and below-ground bi.mass （WWG and BG）. For two N treatments （no N added, addi.i.n of 100 mg N kg^-1soi.）, addi.i.n of N si.ni.i.antly i.proved plant above- and below-ground bi.mass of WWG and BG under water fi.ld capaci.y. Both above- and below-ground bi.mass of the two grass speci.s i.creased li.early wi.h i.creasi.g water suppli.d, but above- and below-ground bi.mass of WWG was always lower than BG for the same treatments （water or N addi.i.n）. The results demonstrated that BG seedli.gs had better adaptati.n than WWG to deal wi.h the i.posed drought or N defi.i.nt condi.i.ns.
