Linear objects impact on grassland degradation in the typical steppe region of China

Despite growing recognition of the issue of grassland degradation, few regional estimates of linear object impacts on grassland degradation [1]. We presented a methodology for evaluating regional impacts on steppe degradation from linear objects which were two uppermost types, rivers and roads, in the typical steppe region of northern China. Spatial accessibility to water resources and roads were thought to influence grasslands degradation of Inner Mongolia. Due to their different attributes originated from nature or human, these two linear objects could respectively show the impacts on steppe degradation.
