Gradient analysis on the influence of terrain on the forest landscape pattern in the burned blanks of the north slope of Mt. Daxing''anling
地形对大兴安岭北坡林火迹地森林景观格局影响的梯度分析

On May 6, 1987, a catastrophic forest fire took place on the northern slope of Daxing'anling Mountains, which burned out more than 1.33×10~6 hm~2 of natural forest and produced a strikingly heterogeneous mosaic of burned severities and islands of unburned vegetation across the landscape. Due to natural succession and anthropogenic disturbance, after more than ten years, the spatial pattern of the landscape has changed greatly. In this paper, a typical area was selected for a case study, which belongs to the...
