在综合80年代以来国内外地植物遥感技术领域最新研究成果的基础上,总结出地植物遥感找矿的基本原理,阐述了目前已知的植物光谱反射特征以及植物受压后所产生的反射率变化.影象色调异常,并介绍了近年来国内外在这一领域的十一个有代表性的研究实例。指出利用地植物遥感技术找矿的两个关键是:①揭示植物光谱反射特性的变化、植被覆盖区遥感影象色调异常与植物受压后产生的变异之间的关系;②确定这些变异是否是由烃类、重金属等矿产有关的“压力”引起的。最后,预测了地植物遥感技术发展的三种趋势:①进一步根据植物的光谱特性研究植物内部的生物化学过程以及压力对植物内部生物化学过程的影响;②开展以地植物遥感信息为主的多源信息综合研究,进行多种技术结合的找矿勘探;③研制新一代的窄光谱、超多波段的高光谱、高空间分辨力的地植物研究专用遥感器。
Based on the latest research results of plant remote sensing technology both at home and abroad since the 1980s, the basic principles of remote sensing prospecting for geophytes were summarized. The characteristics of plant spectral reflectance and the changes of reflectivity The image is abnormal in tone, and the eleven typical examples in this field at home and abroad are introduced. It is pointed out that the two key points of prospecting for the use of plant remote sensing are: (1) revealing the changes of the spectral reflectance characteristics of the plant, the relationship between the abnormal color tone of the remote sensing image of the vegetation cover and the variation after plant compression; (2) determining whether these variations are By hydrocarbons, heavy metals and other minerals related to the “pressure” caused. Finally, we forecast three trends in the development of plant remote sensing technology: (1) further studying the biochemical processes in plants and the effects of stress on the internal biochemical processes according to the spectral characteristics of plants; (2) carrying out more plant remote sensing information Comprehensive study of source information, exploration and prospecting with combination of various technologies; and (3) development of a new generation of special sensor for the study of hyperspectral and high spatial resolution hyperspectral and terrestrial plants with narrow spectrum and ultra-multi-band.
