河北省坝上高原土地资源动态遥感监测

Dynamic Remote Sensing Monitoring for Land Resources of Hebei Bashang Plateau

通过对河北省坝上高原地区不同时期的遥感资料进行分析,认为引起坝上高原生态环境变化的原因是土地利用状况的变化.在土地利用状况中对生态环境变化起主导作用的因素为牧地、耕地、林地.因此,要维护坝上高原的生态平衡,促进当地农林牧生产的发展,必须对土地利用进行合理调整.

Based on the analysis of remote sensing data of different stages of Hebei Bashang plateau area, the author thinks that the changes of the plateau ecological environment are caused by the changes of the land utilization condition. In the land utilization condi- tion, such factors as pasture, farmland and woodland play a dominant role in the ecological environment. Therefore, in order to main- tain the ecological balance of Bashang plateau and promote the development of local agriculture, forestry and animal husbandry, it is necessary to make reasonable adjustments to the land utilization.
