摘要
遥感技术监测土壤水分和干旱具有其它监测手段不可替代的优势。我国自80年代以来,在有无植被覆盖方面使用热惯量方法和植被指数进行了各种尝试和探索,总结出了多种遥感监测干旱的方法,在不同区域的监测中取得了较好的效果;并介绍了干旱遥感监测的发展趋势。
Remote sensing technique has superiority in monitoring soil moisture and drought. The thermal inertia and vegetation index methods have been used in covered and uncovered vegetation since 1980' s. Some kinds of monitoring drought methods were studied in China. Good service effects were acquired by applying these methods in the different areas. In this paper, these methods were summarized and the development trends of drought remote sensing monitoring were introduced.
