河北省坝上高原风蚀沙化遥感监测及防治对策

The Remote Sensing Monitoring of Wind Erosion Induced Desertification in Bashang Plateau,Hebei Province

运用不同时期的航空像片和ＴＭ假彩色合成卫星像片等大量翔实的资料，对河北省坝上高原土地利用现状进行分析研究，摸清土壤风蚀、沙化的发生及发展规律。提出建立土地利用优化模式，完善最优放牧模式。

This paper,first,describes the present land utilization in Bashang Plateau Hebei Province,by analyzing the aerial photographesat and the TM satellite images of this area in different periods.Then,the patterns of the land desertification process are discussed.Finally,the measures to optimize the land utilization are proposed to improve the ecological agriculture engineering practice in this area.
