| 摘 要： | 目的]探索紫茎泽兰的遥感监测技术。方法]以四川省凉山州西昌市为试点,对紫茎泽兰样地的群落数量特征和遥感植被指数进行了相关性分析。结果]在RVI、NDVI和PVI 3种植被指数中,RVI与紫茎泽兰群落高度、盖度和生物量的相关系数均大于0.7,说明RVI对紫茎泽兰等高植被群落最敏感,与其群落数量特征的相关性最好,能较好地反映群落的特征;各植被指数与紫茎泽兰群落地上生物量的相关程度差异不大;各植被指数中,紫茎泽兰生物量与NDVI的相关系数最小,盖度与PVI的相关性最低。结论]利用RVI可对紫茎泽兰的危害情况进行有效监测。 |

| Abstract: | Objective] The aim was to study the remote sensing technology of Eupatorium adenophorum Spreng.Method] With Xichang City in Liangshan Prefecture of Sichuan Province as the experimental unit,the correlation of community numerical characteristics and applying rs vegetation indexes of E.adenophorum in sample plot was studied.Result] In 3 kinds of vegetation indexes(RVI,NDVI and PVI),the correlation coefficients of RVI and community height,coverage and biomass of E.adenophorum were all higher than 0.7,which ... |
