| Abstract: | The karst rocky desertification is an eco-geological problem in South China,concerning how to monitor its changing precisely,rapidly and economically and to restore it and make a study on its evolution.Based on primary theory and methods of RS dynamic monitoring technology,a general technical way is tested by choosing RS image,data preparation,obtaining the changing image of rock desertification,and classifying it.The technique of second time classification and extracting information of rocky desertification by mended EVI is practical and the monitoring result is precise through the study on test area and the application of large scale and random validating. |
| Keywords: | karst area rocky desertification remote sensing monitoring south China |
