摘　　要：基于RVoG模型,对传统三阶段算法及其改进算法进行研究,以云南省西双版纳州勐腊县为研究区,以TerraSAR-X/TanDEM-X数据为数据源进行森林高度反演算法研究,并结合野外实测数据进行结果验证。结果表明,三阶段改进算法对森林高度反演精度优于传统三阶段算法。三阶段改进算法对天然林高度反演精度较高;三阶段算法对橡胶林高度反演精度较高。Based on the RVoG model,the three-stage algorithm and its improved algorithm were studied.In Mengla County,Xishuangbanna,Yunnan,TerrasAR-X/tandem-X data were used as data sources to conduct forest height inversion algorithm.Finally,the results were verified by field measurement data.The results showed that the accuracy of the improved three-stage algorithm was better than that of the traditional three-stage algorithm.For natural forest and rubber forest,the improved three-stage algorithm had higher accuracy in height inversion of natural forest.The accuracy of the three-stage algorithm for rubber forest height inversion was high.
