Abstract:

Based on the ZY-3 satellite data related to the Shendong coal mining area, the matic remote sensing interpretation marks were established for artificial influencing factors of land degradation in the area, the factors monitored via remote sensing, a comprehensive intensity evaluation index system built up for the factors with the AHP method, and strength indices of the factors worked out with the comprehensive evaluation method. It turned out that land occupation by waste was the major form of land degradation caused by artificial influencing factors, and the influence of mining activities on land degradation in this area had reached the level of “strong”. To estimate quantity of the land resources occupied or to be occupied by waste and predict the trend of the land degradation as a result of development of the mining area, an algorithm was proposed for calculation of land occupation and damage rate in the coal mining area. The research shows that the ZY-3 satellite data are adequate to completely satisfy the requirements of the survey of land degradation caused by underground coal mining for high resolution satellite remote-sensing data, and it is essential to intensify orderly and effective management of coal mining and to monitor dynamics of the environment of the mining area via remote-sensing in order to stop the aggravating trend of the influence of the artificial factors on land degradation.
