The Index System and Methods of Monitoring Damaged Cultivated Land Quality in Mining Area Based on Agricultural Land Classification

摘要

Damaged cultivated land reclamation in mining area is one of the important ways to remediate the cultivated land in China. In the study, Index system of monitoring damaged cultivated land quality in mining area was established on the basis of agricultural land classification indexes. Collapse depth, excavation depth, cover occupation height, density of fractures, and the additional slope are added to reflect the characterization of micro topographic. Methods which are used to monitoring damaged cultivated land quality are summarized according to the condition of mining area. The connection between "gradation of agricultural land (upper level)" and "damage level (lower level)" is established. These measures could make the results of land reclamation management effectively and directly serve the update of agricultural land grading results.
