| 摘 要： | 利用混合像元线性分解模型提取植被覆盖中等的辽南卧龙泉地区植被丰度图像，并依此进一步提取了该区域的粘土类蚀变信息。在使用混合像元线性分解基本模型的同时，也结合研究目标对其进行了改进与补充，效果令人满意，为中等植被覆盖区的专题信息的提取提供了一种方法。 |
| 关 键 词： | 混合像元线性分解 中等植被覆盖 卧龙泉地区 粘土类蚀变 辽宁省 |

| Abstract: | Based on the linear decomposition model of MSA, this paper manages to get the vegetation abundance of the study area, then extract the clay-alteration information and make some supplements to the basic linear model of MSA. Field survey and other information show that the practice of this paper can be adopted to extract thematic information for such areas with medium vegetation cover. |
| Keywords: | linear decomposition of mixture pixel medium vegetation cover Wolongquan area clay-alteration Liaoning province |
