| 摘 要： | 根据植被指数估算植被覆盖度的原理,以混合像元线性分解模型两个重要参数为基础,建立基于归一化植被指数(NDVI)进行估算植被覆盖度模型是研究区域植被覆盖度的一种重要方法.本文以广州市花都区为实验区,利用ASTER高光谱影像对此方法进行验证性分析,实验结果表明:用该方法提取ASTER影像的植被覆盖度具有较好的可行性.

| Abstract: | It's an important way to establish a vegetation coverage estimation model from NDVI(Normalized Difference Vegetation Index)to study the condition of regional vegetation coverage.And the model is based on the sub-pixel model's two important parameters.This paper takes HuaDu district of Guangzhou City which lies in the subtropical region as an experimental area,and using ASTER image to check this model.The result showed that this method could satisfy the quantitative requirement of the model,and could be appl... |
