摘要
采用GPS信号反演土壤湿度具有重要的科学研究意义。对于干旱荒漠化矿区地表大多为裸地或低植被覆盖条件,适宜于土壤湿度的遥感。本文探讨了利用GPS信号反演土壤湿度的理论和方法,在分析荒漠化矿区地表特点的基础上,讨论了在荒漠化矿区利用GPS信号反演土壤湿度的可行性。
It is significant to measure soil moisture by GPS reflected signals. In arid mine area, it has lower vegetation cover rate due to land desertification. However it is suitable to measure soil moisture by remote sensing within this context. In this paper, it provided the methodology to monitor soil moisture using GPS reflection signals and discussed the potentiality and feasibility to apply this alternative approach for remotely sensing soil moisture within arid desertification mine area.
