介绍了一种运用陆地卫星ＴＭ数据监测马尾松林分针叶量及其变化的方法，只要由森林资源清查数据建立起林分资源信息库后，就可通过监测年份卫星数据与背景数据的比较，初步了解森林的健康状况。并通过宏观的监测结果，森防人员根据多年的经验就可预测发展趋势，制定出相应的防治策略，进而实现宏观监测和预测森林病虫害的目的。
This paper introduces a method of monitoring Pinus massoniana forest needles and its changes using Landsat TM data. Once the information database of forest resources is set up based on the inventory data of forest resources, the satellite data of the years can be compared with the background data Understand the health of the forest. Through the macroscopic monitoring results, forest defense personnel can predict the development trend based on years of experience and formulate corresponding prevention and control strategies so as to achieve the purpose of macro-monitoring and prediction of forest pests and diseases.
