Abstract: Hulun Buir steppe is located in northeast China.It is one of the most famous steppes in China. The present paper Consists of four parts.In the first part,the natural conditions in Hulun Buir steppe are briefly described.It belongs to a transitional belt between the sub-humid and semi-arid regions in the temperate zone. The steppe can be divided into two natural zones and five sub-zones.In the second part,the main characteristics of the land resources are analysed according to land types.The lands located in various sub-zones have different landuse suitabilities.The land conditions in the steppe are quite favorable for the development of animal husbandry,but some of the lands located in the eastern steppe are good for farming,although there are also some unfavorable natural conditions,such as low temperature,frost,drought,soil erosion and wind hazard.In the third part,the present land-use in the region is studied. The major part of the lands is used for animal husbandry,although the present land use is suitable to the natural conditions in the region,most of the lands that can be used for farming and/or forestry is still not fully utilized. In the last part,the problem of optimal landuse are probed.According to the suitabilities of the land resources,the steppe is divided into a few land-use regions,and the land-use measures are also discussed.
