中文摘要	呼伦贝尔草原是我国优质的天然牧场和重要的畜牧业生产基地.近年来,该草原中的砂质草场已大面积发生沙漠化.通过实地调查研究,并结合遥感资料和前人研究成果,本文在分析了呼伦贝尔草原沙漠化现状和发展态势的基础上,着重从地质环境变化和人类活动两个方面探讨了该区沙漠化的成因.认为沙漠化的发展是自然因素与人为因素共同作用的结果,地质环境因素是形成沙漠化的基础,地表的土壤和植被是草原良好的保护层,人类对草原的破坏是导致沙漠化的直接原因.最后,对沙漠化的防治提出了3点建议.
英文摘要	Hulunbuir Steppe is one of the high quality natural pastures and important livestock husbandry ba-ses in China. But in recent years, sandy desertification occurs in the large areas of sandy grasslands in Hu-lunbuir Steppe. According to the achievements of on-the-spot investigation, remote sensing and previous re-searches, the present situation and evolution trend of sandy desertification have been discussed in this pa-per. The cause of sandy desertification is also approached through analyses on geological environment chan-ges and human activities. Finally, it is considered in this paper that sandy desertification of Hulunbuir Steppe results from the outcome of natural changes and human activities; and geological environment is the basis of sandy desertification development; while the surface soil and vegetation are sound protective um-brella of steppe; however the direct cause of sandy desertification is human s great damage to steppe. Final-ly, authors offer three proposals for sandy desertification control.
