Remote Sensing Monitoring and Effect Evaluation on Ecological Restoration of Heidaigou

摘要

With the rapid development of society and economy, the increasing demands of coal resources not only caused the over-exploitation, but also damaged the ecological environments. So it is important to restore the mining areas, which largely means vegetation restoration. This paper takes Heidaigou mining area as the study area to get an idea of how to monitor and restore the Heidaigou mining area effectively. The data used in the research are Landsat images and CBERS images that taken from 2001 to 2010 between June and October. By analyzing the images of study area with the technologies of remote sensing and geographic information system, we get the interpreted images of typical surface features of Heidaigou mining area. The results show that the area of exposed soil of waste-dump is increasing in Heidaigou mining area, which means the intensity of exploitation is rising. Besides, the growing area of vegetation restoration shows that the intensity level of restoration is also ascending year after year in Heidaigou mining area.
