| 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,选取了不同时相的三期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G IS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、TM4/TM3、TM(4-3)/TM(4+3)是监测松毛虫害的特征指数。根据雷莉萍等(1995)构建的遥感监测模式,建立了油松毛虫遥感监测模型,经现地检验,平均精度达到85.67%。

| Abstract: | Taking stands of 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 phonological information,contrasting the growth and spectrum characteristics of stands between pre and post the damage,7 types of vegetation indices and the spectrum val... |
