Determination and Classification of the Damaged Cultivated Land Boundary a Case Study at Yanzhou, China

Currently, the environment of the coal mine area is serious damaged by coal mining activities, and measures are imperative for the damaged cultivated land protection. This paper describes a new method and criterion for the boundary determination and classification of the damaged cultivated land caused by coal mining subsidence. The establishment of the demarcation criterion is achieved by comprehensive analyzing the influence of the groundwater depth, surface inclination, and the Visual Cultivated Land Sensitivity (VCLS). For the new criterion validation, the DEM and additional slope of the Yanzhou coal mining area are generated and the damaged cultivated land is classified into three grades. The results show that this criterion can be used to be the reference basis for the boundary determination and classification.
