Effects of Different Land-use Patterns on Reclaimed Soil Aggregates and Organic Carbon in a Coal Mining Subsidence Area

1. The data were collected from the reclaimed area of Dongtan Mining Area in Zoucheng, Shandong Province, including plots with different land use modes such as farmland, woodland, and wasteland, with additional normal farmland and woodland in the surrounding area as a control.2. Sample collection was carried out in April 2016, and three sampling points were set up in each land-use pattern sample plot, and the 0–20 cm and 20–40 cm soil layers were extracted with a specific stainless steel sampler and mixed in layers.3. involving data on particle size distribution and stability characteristics of soil aggregates, grouping particle sizes by wet sieve method and described by R0.25, MWD, GMD, and D.4. data covering soil aggregate organic carbon content, contribution rate, and each organic carbon component (e.g., free light group, particulate organic carbon, mineral-bound carbon, etc.), measured and analyzed by the density combination method, etc.
