摘要
高光谱遥感具有波段多且光谱连续等特点,在土壤质量信息的监测方面,利用高光谱遥感数据,能够实现对土壤特性的定量分析。总结了利用高光谱遥感技术获取土壤质量信息的方式和特点,以及影响土壤光谱反射特性的主要因素,回顾了国内外基于遥感的土壤质量信息提取的定量研究,并对研究中的问题进行了分析和展望。
Hyperspectral remote sensing is characterized in multi and continuous spectrum, which can be used in the monitoring of soil quality information. The hyperspectral remote sensing data can be used to do the quantitative analysis of soil characteristics. This paper summarizes the mode and characteristic of extraction of soil quality information based on hyperspectral remote sensing technology, analyses the main factors that influenced the soil spectral reflection characteristic, reviews the studies of quantitative extraction of soil quality information based on hyperspectral remote sensing in domestic and abroad. Finally, analyses the problems and draws the prospect in the related areas.
