摘要 详细论述了旱情遥感监测中特征空间法的技术原理及应用方法,通过大量遥感数据资料分析,阐述了地面温度—植被指数特征空间与土壤湿度的相互关系及实际应用方法。 This paper discusses technique principle and applied methods of the the characteristic space method in drought monitoring with remote sensing.By analysis of a great deal of remote sensing data, it elaborates the characteristic space interrelation and actual applied methods of surface temperature and vegetation index to soil moisture.
