摘要
干旱监测的主要方法包括土壤含水量的中子仪测量法、TDR测量法、湿度计法、称重烘干发法以及几种卫星遥感监测方法等。对各类干旱监测方法存在的问题和发展趋势进行探讨,并提出加强我国干旱遥感监测技术研究的建议,为我国农业旱情监测提供一定的帮助。
The method of drought monitoring mainly includes soil moisture neutron measurement, TDR measurement, humidity meter, weighing drying method and several satellite remote sensing monitoring methods. In this paper, the author expounds on the existing problems and the development trend of drought monitoring methods, and proposes to strengthen the research of remote sensing technology in China＇s drought monitoring hoping to provide certain help for agricultural drought monitoring in ＇China.
