【Objective】In the primary energy structure of China, coal will remain to be the main component for a long time. The aim of this study was to explore mechanisms for soil moisture, nutrients and particles migrating and transforming in the micro topography of a slope in the coal mining subsidence area, and to provide an important basis of theoretical and practical values for scientific decision-making for comprehensive management of eco-environment in mining areas. 【Method】Cultivated land and forest land in a plain coal mining subsidence, typical of the JIULISHAN mining in Jiaozuo City, Henan Province, China, were selected as object of the study. Soil samples were collected from various layers (0~10 cm, 10~20 cm, 20~30 cm, 30~40 cm and 40~50 cm) of the soil profiles various in position (center, bottom, middle, top and control) along a subsidence slope of cultivated land and forest land for analysis of moisture content, organic matter content and texture. And then a comparative analysis was done of the acquired data for determination of spatial variability of the indices. 【Result】It was found that the cultivated land was significantly lower (p<0.05) in soil moisture content and clay content (<0.002 mm) but significantly higher (p<0.01) in sand content (2~0.02 mm) than the forest land. Along the slope the soils in the middle or bottom were the lowest in soil moisture content, organic matter content and silt content (0.02~0.002 mm) but the highest in sand content and clay content, while along the soil profiles, significant accumulation of soil moisture, organic matter and sand were observed in the surface layer, but that of soil clay was in the bottom layer. Along the slope of the subsidence area, soil properties of the forest land varied largely with slope gradient, and infiltration flow of soil percolating water intensified horizontal variability of soil organic matter, sand and clay content, forming obvious clay deep soil layers (> 30 cm) and carbon “pools” at the bottom of the slope of forest land. However, in the cultivated land, soil properties were mainly affected by cracks, and priority flow of soil percolating water dulled vertical variability of the soil texture, meanwhile affected by slope gradient, horizontal surface flow appeared, forming obvious sandy surface soil layers (0~20 cm) and carbon “source” in the middle and bottom of the slope of cultivated land.【Conclusion】It is, therefore, suggested that the land in such plain subsidence in coal mining areas should be reclaimed mainly into cultivated land and then into forest land as complement. After the subsidence was temporarily stabilized, as the first phase of land reclamation, the lands in the center of the subsidence and on the upper-slope should be reclaimed into farmland to avoid further loss of clay and soil degradation, while lands at the mid- and down slopes, be turned into contour forest and shrub belts, about 40~60 m wide and corresponding to the underground coal mining roadway boundary. Both of the stops may play a key role in controlling soil water and nutrient losses and improving eco-environment of the area.
