| 摘 要： | 以TM图像为数据源，以重庆南川市为例，结合地面调查数据，利用ERDAS遥感处理软件，对植被覆盖度信息提取方法、植被覆盖度与植被指数的关系、植被覆盖度分类、土壤侵蚀与植被覆盖度等进行了研究。实验结果表明：随着植被覆盖度的增加，土壤侵蚀强度逐渐减弱，特别是流失等级越高，递减越明显。 |
| 关 键 词： | TM图像 植被指数 植被覆盖度 土壤侵蚀 |

| Abstract: | Supported by the field investigation data in Nanchuan City,Chongqing Municipality,the TM data were processed by(using) the remote sensing software ERDAS IMAGINE 8.5.Four facets were studied as follows:the extracting method of vegetation coverage rate,the relationship between vegetation coverage rate and vegetation index,vegetation coverage rate classification,and the relationship between soil erosion and vegetation coverage rate.The results showed that:as vegetation coverage rate increased,the extent of soil erosion decreased.And the higher soil erosion level was,the more obviously soil erosion decreased. |
| Keywords: | TM image vegetation index vegetation coverage soil erosion |
