Spatial distribution characteristics of arable lands in Taihang Mountain area of Hebei Province

Based on the application of RS and GIS technologies, this paper analyzed spatial distribution characteristics of the arable lands in Taihang Mountain area of Hebei Province. The results show that 80.9% area of the mountain arable land distributes below 500 m elevation, 93.7% area distributes with less than 15° slope gradient and 70.3% area distributes in flats and U-shaped valleys. This indicates that the exploitation of arable land resources in Taihang Mountain area of Hebei Province is reasonable. The research conclusion could be used as the reference on quality assessment and utilization of arable land resources in other areas of Taihang Mountain.
