摘要

用337nm氮分子激光照射不同种类的植物

可以得到每一种类植物的激光诱导荧光特征光谱。利用峰的波长

荧光强度的差异可以将木本阔叶树、针叶树

草本双子叶及单子叶植物加以区分。685与740以及440与550nm的荧光强度比值均可以作为植物区分的两种参数。用激光诱导荧光技术监测植物要选择合适的生长期和季节

单子叶植物应选拔节期

双子叶植物应选营养生长期

而木本植物则应选在春末夏初。研究表明

激光诱导荧光遥感技术对植物鉴别与分类以及植物的长势监测具有极其重要的意义和应用前景。

Abstract

Laser induced fluorescence spectra of various plants can be obstained by illuminating with 337 nm N2 laser.Differences among peak wavelengthes and peak intensities can be used to distinguish woody broadleaf trees and coniferous trees

as well as herbaceous dicotyledon and monocotyledon. Fluorescence intensity ratios of 685 nm/740 nm and 440 nm/550 nm can be used as two parameters to distinguish plants. Suitable period and season should be selected for detecting plants when using the technology of laser induced fluorescence

the optimum detecting period of monocotyledon in joining stage

dicotyledon branching stage

woody plants between late spring and early summer. The paper also discribed the identification and classfication of plants

as well as the significance and application propects to monitor growth vigors of plants using the technology of laser induced fluorescence.
