| 摘 要： | 文根据遥感影像资料, 在对河北省境内太行山区域耕地资源进行解译的基础上, 应用GIS技术和空间分析方法, 对其空间分布特征从海拔高度、坡度及地形类型3个方面进行了分析研究。结果表明, 河北省太行山区域耕地的80.9%分布于海拔500 m以下, 93.7%分布于坡度15°以下, 70.3%分布于平地和U型谷地。由此可以看出, 目前河北省太行山区域耕地资源开发利用比较合理。本文对河北省太行山区域耕地资源空间分布特征的分析可为太行山区域耕地质量评估和合理利用提供科学依据和支持。

| Abstract: | 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. |
