Monitoring of Karst Rocky Desertification Control Projects Based on Remote Sensing Images with Medium and High Spatial Resolution --A case study of Disi River Basin in Puan County

摘要

[Objective] The study aimed to improve methods of monitoring Karst Rocky Desertification( KRD) control projects and increase the working efficiency.[Method] Based on remote sensing images with medium and high spatial resolution,KRD control projects in Disi River basin in Puan County were monitored,that is,information of the project construction in the study area was extracted using supervised classification and human-computer interactive interpretation,and the monitoring results were testified with the aid of GPS.[Result] It was feasible to monitor KRD control projects in Disi River basin based on remote sensing images with medium and high resolution,and the monitoring accuracy was satisfactory,reaching above 80% or 90%,so the method is worthy of popularizing.[Conclusion] Remote sensing images with medium and high resolution can be used to monitor other KRD control projects.
