| 摘 要： | 松材线虫是一种危险的外来入侵种,对我国的森林资源破坏很大。而遥感技术作为一种先进的空间信息技术,在森林病虫害监测方面具有独特优势,而受害林木实测光谱的研究对于遥感监测具有重要的意义。通过对马尾松4种不同受害类型的林木进行反射光谱测量,并对光谱反射曲线进行一阶微分分析,研究了绿光区、红光区和近红外区反射光谱的变化特征,为应用遥感技术研究松材线虫入侵过程中,森林资源动态变化提供了实验依据。

| Abstract: | Bursaphelenchus xylophilus,a alien species,has destroyed lots of forests in China.As a advanced spatial information technology,RS(Remote sensing)has more advantages in monitoring forests suffered by pests and diseases,and the spectral characteristics analysis is very important for studying forests suffered by pests and diseases with RS.In this research,4 different types of Pinus massoniana were studied by measuring reflectance,plotting spectrum and differential spectrum.Then,the reflectance comparison in green,,red and near infrared bands among 4 types was finished.This study can provide an experimental reference to harmed forest dynamic monitoring with RS. |
