根据松毛虫的生物特性和森林虫害的波谱特征，建立遥感监测模式和监测流程。模式的关键是植被指数的选择和计算以及植被指数变化与针叶生物量损失的关系建立。植被指数的选择以比值指数较佳；由常规林业调查建立植被指数与虫害等线划分的关系。以福建省建欧县为试区，用建立的模式和流程进行虫害预测和评价获得令人满意的结果。
According to the biological characteristics of pine caterpillars and the spectral characteristics of forest pests, the establishment of remote sensing monitoring model and monitoring process. The key of the model is the establishment and calculation of the vegetation index selection and calculation and the relationship between the change of vegetation index and the loss of needle biomass. The choice of vegetation index is better than the ratio index; the relationship between vegetation index and pest equalization is established by routine forestry survey. Taking Jianou County of Fujian Province as a pilot area, satisfactory results were obtained by using the established models and procedures for pest prediction and evaluation.
