高光谱遥感在草地中的应用及研究进展

Research advances of hyperspectral remote sensing application in grassland

我国是世界第二草原大国,有效、快捷、连续、大范围地监测草地植被状况及其动态变化对合理利用草地资源、实现草地畜牧业的可持续发展具有重要的技术支撑作用。文章从高光谱遥感在草地中的应用及研究进展进行了综述,结果发现,草地高光谱研究以其快速、便捷、准确等优势,在区域和全球尺度上已经广泛应用于草地遥感估产、草地退化监测、牧草品质测定、草地种类以及草地花期识别等方面。未来,高分辨率影像数据结合遥感生态学测量及各种先进技术、各种数据分析、处理方法,对草地实现定量分析及动态监测,具有广阔的应用前景。

Our country has the world＇s second largest grassland area in the world,effective,efficient,continuous,large-scale monitoring of the conditions and its dynamic changes of the grassland,plays an important supporting role in reasonable utilization of grassland resources to realize the sustainable development of grassland animal husbandry.In this paper,research progress and application of hyperspectral remote sensing in grassland were reviewed.The results showed that hyperspectral remote sensing with its fast,convenient and accurate advantages had been widely used in grassland yield estimation,grassland degradation monitoring,and quality measurement of forage,grassland species,flowering meadows and recognition and so on in the regional or global scale.In the future,high resolution image datas,combined with remote sensing ecological measurements and a variety of advanced technology,and a variety of data analysis and processing method to achieve quantitative analysis of grassland and dynamic monitoring,has a broad application prospect.
