中文摘要	通过对车辆碾压后的呼伦贝尔沙质土壤草甸草原的野外调查和土壤样品的室内分析,对车辆碾压引起草地植被和土壤的变化进行研究。结果表明,草地地下生物量和土壤有机质、土壤全氮、土壤速效氮、速效磷随着碾压程度增强和车辙深度加大而呈下降趋势,速效钾没有明显的规律。车辆碾压破坏植物群落地上部分与根系,导致群落地下生物量和土壤养分显著减少,并促进风蚀导致表层土壤流失。控制草原区机动车碾压,保护草原植被和表层土壤,对于防止车辆碾压而造成土壤流失形成草原沙漠化极为重要。
英文摘要	Through field investigation of Hulunbeier sandy meadow grassland which was roller compacted by vehicle and relevant samples by laboratory analysis,the research was made on grassland vegetation and soil changes caused by the vehicles rolling. The results showed that the grassland underground biomass,soil organic matter,soil total nitrogen, soil available nitrogen and phosphorus significantly decreased with increased of the roller compacted extent which resulted in depth rut(P < 0. 05),available K increased firstly and then decreased. Vehicle rolling destructed above-ground plant communities and roots,significantly reduced in below-ground biomass and soil nutrients,and promoted wind erosion which led to the loss of topsoil. Therefore,control of the vehicle rolling and protection of grassland vegetation and topsoil are extremely important to prevent soil erosion break formation caused by vehicle rolling and to combat grassland desertification.
