| 摘 要： | 归一化植被指数（NDVI）是目前用以表征植被覆盖、生长状况的一个简单、有效的度量参数。本文以弥勒县1992年4月及2006年6月的两景不同时期的TM影像数据为基础，提取NDVI植被指数并进行优化处理，做出植被覆盖的基本分类，并将所得数字图像在Arcgis平台上进行面积统计，最后通过统计变化数据得到弥勒县的植被覆盖变化情况。

| Abstract: | The normalized difference vegetation index （NDVI） is a simple and effective parameter to characterize the vegetation coverage and its growth status. From the TM image data of Mile County in April of 1992 and June of 2006, the NDVI index was extracted and optimized, and the vegetation cover was basically classified. On the Arcgis platform, the area was calculated and the change of the vegetation cover is obtained based on the statistical data. |
