| 摘 要： | 以辽宁省西部地区油松林为例,根据当地物候特征和油松毛虫的生物学特性,选取了不同时相的3期TM影像,进行了松毛虫灾害前后油松林受害程度的调查。结合GIS专题信息图,比较分析了油松毛虫灾害前后油松林的生长特征和光谱特征,计算出7种植被指数和TM4在松毛虫害发生后油松的光谱值,得出TM4/TM3是监测松毛虫害的特征指数。建立了油松毛虫遥感监测模型,经现地检验,平均精度达到86.55%。

| Abstract: | Taking Pinus tabulaeformis in western Liaoning as an example,based on the local phenological & biological characteristics of Dendrolimus tabulaeformis,3 periods of different TM imageries were selected.Investigation for damage situation of Dendrolimus tabulaeformis were conducted pre and post damage emergence.Combining GIS data and phenological information,the paper contrasted the growth and spectrum characteristics between pre and post damage.7 types of vegetation indices and the spectrum values occurred af... |
