Agricultural suitability assessment and rehabilitation of subsided coal mines: a case study of the Dawu coal mine in Jiangsu, Eastern China

Abstract Land-use suitability assessment crucial is for coal mine rehabilitation planning, especially the mines that have undergone varying degrees of mining subsidence. In this study, we present an on crop cultivation in Dawu district NW Jiangsu province, Eastern China. Distribution local land subsidence delineated with topographic analysis, and weight-of-evidence (WoE) has encompassed various factors including conditions soil (e.g., acidity porosity), groundwater level, irrigation drainage, terrain slope, pollution. Consequently, divided into four categories (high, moderate, low, very-low) agricultural suitability. Collaborating government agencies Land Resources Bureau Agriculture Bureau), a land-use plan proposed. plan, highly suitable areas agriculture (and surrounding moderately areas) are allocated as farmlands, whilst other to lowly ecological zones restoring ecosystem diversity. The barely severe artificial lakes, which also serve reservoirs farmland drainage. To protect these new farmlands from erosion, infrastructure such embankment windbreak included our plan. Our study highlights necessity forward planning rehabilitation.
