To study the arid land use,soil modified and vegetation restoration on sandy nutrient effect,the research is carried out in the Ulan Buh Desert northeastern margin.The results showed that land use and human activities on desertification and rational management to restore and improve land fertility,have greater influence in the agricultural farming systems,its improving soil fertility and crop rotation of grass as the highest,followed by crop intercropping,crop monoculture minimum.In the desert sand,crops have more ability than fruit to protect soil ecological environment; afforestation in the desert sand,protection forest should be mainly,not to create large-scale poplar forest; in the sand to create a fuelwood,can play an improved effectiveness of barren sand; planted in the Astragalus adsurgens Pall.,Melilotus suaveolrns Ledeb.and Medicago sativa L.can effectively improve the sandy soil fertility,Astragalus adsurgens Pall.was the best,Melilotus suaveolrns Ledeb.,Medicago sativa L.was the worst; grass in the fenced sand sports,different plant communities on sandy soil improvement effect of different,plant communities better than the single.Order of nitrogen and phosphorus ratio were Nitraria tangutorum Bobr.+ Artemisia ordosica Krasch.>Artemisia ordosica Krasch.+Psammochloa villosa>Artemisia ordosica Krasch>Psammochloa villosa>Oxytropis glabr+Artemisia ordosica Krasch.>Nitraria tangutorum Bobr.>Oxytropis glabr,the level of soil nitrogen and phosphorus ratio main depends on the nitrogen level.
