Affect of fencing on community structure and species diversity of Eragrostis nigra on degraded grassland in Karst Area

摘要：

Introduction Backspiked lovegrass ( Eragrostis nigra ) played a very important role in grassland resources in Karst area However,because of over grazing in the long past,it caused a serious degradation of grassland and heavy soil erosion,leading to the continual expansion of bare land in the area.The trial,through three-year observation,was aimed at effect of restoration of Eragrostis nigra vegetation on the degraded grassland by means of fencing so as to provide theoretical foundation and practical measures for sustainable utilization of the grassland in karst area.
