遥感植被指数在重点国有林区“三总量”伐区检查中的应用研究——以对鹤立林业局的研究为例
Application of RS Vegetation Index in Forest Cutting-area Detection for "Three Total" Inspection in State-owned Forest Regions——A Case Study in Heli Forestry Bureau
【摘要】 以鹤立林业局为研究区域,以2007年"三总量"检查的TM遥感判读区划结果和抽样现地检查结果为基础资料,分析了同期遥感数据之间、不同年份遥感数据之间采伐地块的植被指数变化,以及不同采伐方式和不同采伐强度与植被指数变化的关系,为利用遥感数据进行"三总量"检查进行了有益的探索和实践。
【Abstract】 Using the results of TM image interpretation and field sampling investigation of "Three Total" inspection in 2007 in Heli Forestry Bureau,the paper analyses NDVI changes of TM data in forest cutting-area and analyses the changes relationship between different cutting modes and different cutting intensities based on TM data of the same year or different years,which provides a useful study on the application of remote sense images in "Three Total" inspection.
