Some conclusions from the study on human driving factor are:(1) the human activity is much more active factor to the process of desertification which mainly incarnates on the changes of the landuse fashion (from traditional rangeland 100 years ago come to interlacing agro-pastoral region) and enhance of landuse intensity (over-cultivation, over-grassing and over-fuel collection);(2) the natural vegetation had been destroyed suicidally by human activities that had accelerated to the development desertification.

在人为驱动力的分析中，得到以下一些初步的结论：（1）人类活动是本地区沙漠化过程中更加活跃的驱动因子，体现在土地利用方式的转变（从传统的牧业草原到今日的农牧交错区）和强度的增加（过度开垦、放牧、樵采等）；（2）由此对自然植被群落毁灭性的破坏，加速沙漠化的进程。

Today, they survive precariously in a few patches, having retreated from 95% of their former domain, in the face of relentless human pressures: clearing of land for farming and grazing, woodcutting for fuel and timber, over-hunting of prey, and killing of tigers themselves.

Results are as following:The causes of grassland desertification of Hulunbeir are the outcome of interaction of nature and the human beings. Among these reasons, the loose soil texture, which was formed in the fluviolacustrine sediment during Quaternary, establish the physical ground, and the drought and wind is the natural force of grassland desertification. And then over-cutting forest, over-grazing grassland, imbalance of resource utilization and estrepement reduce the coverage of vegetation, therefore provide necessary conditions for the grassland desertification.

其中，形成于第四纪河湖相沉积沙的疏松土壤母质，为日后土壤风蚀奠定了深厚的物质基础；干旱多风的气候条件构成了草地风蚀沙化的自然营运力；而人为过度砍伐沙地林木资源、沙质草地长期超载放牧、资源利用不平衡以及乱垦、滥挖等不合理经济行为，又降低了沙化草地植被覆盖度，为草地风蚀沙化提供了必要条件。
