| 摘 要： | 以宁夏灵武油蒿主要分布区为研究地,野外调查并获取了健康及受钻蛀性害虫危害后油蒿冠层光谱的反射率,并应用一阶微分方法处理光谱反射率进行研究。研究表明,健康油蒿受到钻蛀性害虫危害后,具有明显的＂红边＂蓝移现象,同时,利用高光谱数据监测虫害发生是可行的,而且对植株本身不造成任何伤害。该研究为荒漠灌木林是否可利用高光谱数据来进行钻蛀性害虫监测提供了基础。

| Abstract: | A study on the spectral curve change of canopy spectral reflectance of Artemisia ordosica Krasch has been hazarded by borers while acquiring canopy spectral reflectance.Distributed lots of Artemisia ordosica Krash in Lingwu,Ningxia as the study area,and using first derivative to process spectral reflection in the research.The results showed that the obvious phenomenon is blue shift of the red edge spectra after the healthy Artemisia ordosica Krasch are damaged by insect borers.The insect mainly caused damage to roots of Artemisia spp.,it is possible to use hyperspectral data to monitoring the occurrence of insects,meanwhile this method is safe to the plant.The study is provided a basis,while the hyperspectral data can be used to monitor insect borers in desert shrub. |
