摘　　要：草层高度在草地退化和沙化评价、生物量遥感监测、牧区雪灾监测中都具有重要的作用和价值,然而草层高度精确监测和制图一直是草地遥感研究的难点。近年来随着多光谱遥感、激光雷达遥感技术、无人机技术和高光谱遥感技术的不断发展,为草层高度的高精度遥感监测提供了技术支撑。本文在综述草层高度遥感监测研究进展的基础上,归纳了草层高度遥感监测研究存在的问题及展望,以期为草层高度高精度遥感监测研究提供帮助。Grass height plays a vital role in grassland degradation,desertification assessment,remote-sensing monitoring of grassland aboveground biomass,and monitoring of pastureland snow disasters.However,highly accurate monitoring and mapping of grass height has always been a difficult issue in grassland remote-sensing research.In recent years,the continuous development of multispectral remote sensing,LiDAR remote sensing technology,unmanned aerial vehicles,and hyperspectral remote sensing technology has provided technical support for high-precision remote-sensing monitoring of grass height.Based on the review of remote-sensing monitoring of grass height,this paper summarizes the existing problems and prospects of grass height remote-sensing monitoring to provide assistance for high-precision remote-sensing monitoring of grass height.
