| 摘 要： | 植被是生态环境的重要组成要素，它与一定的地形条件相适应。本文以吴起县遥感影像及地形数据为基础，集成使用RS，GPS及GIS技术，以NDVI植被指数计算为核心完成了植被覆盖度的动态监测及分析，植被群落已基本恢复成能与环境相适应的稳定群落，封禁效果基本稳定，林地面积、植被覆盖度等指标明显上升。植被覆盖度面积逐年增加，部分地区还出现了较为明显的逆转现象，整个研究区的生态环境呈现良性发展态势。

| Abstract: | Vegetation is an important element in the eco - environment and adapts to the specific landform. Through the technology of remote sensing, GPS, GIS and NDVI, the paper conducts dynamic monitoring and analysis of the vegetation coverage based on the remote sensing image and topographic data by taking Wuqi county as an example. The results indicate that both the area of woodland and vegetation coverage are better than before. |
