摘要
利用作物光谱反射率进行作物水分实时监测和快速诊断是目前遥感技术在农业中应用的研究热点之一,根据20世纪70年代以来的大量国内外文献,综述了利用光谱反射特性诊断作物水分状况的研究进展,阐明了从光谱反射特性诊断作物水分状况方法的优势,指出了此项研究存在的问题,并对其今后研究方向和发展趋势进行了展望。
Real-time monitoring and rapid diagnosis of crop moisture content based on spectral reflectance is one of the hot problems for the application of remote sensing technology in agriculture. Based on large quantity of literature from 1970s to 2004, this paper analyzes and evaluates the advances on diagnosis method of crop moisture content using the spectral reflectance of crops, and summa- rizes the main research progress in diagnosis of crop moisture content condition from the spectral reflectance. The problems of studies in this field are also pointed out. Furthermore, the trend of research and development in the future is prospected.
