Soil aggregate stability and erodibility in urban riparian zone: a case study of the River Tour Company in Wuhan, China

The samples were taken from three representative sites (Wutaizha, WTZ; Huoshui Park, HSP; Sanchakou, SCK) reflecting different urban activities in riparian zone of River Tour Company in Wuhan, China. Soil physicochemical properties at different spatial locations (sampling site, slope position, and soil depth) were measured. Then, soil aggregate stability indices including mean weight diameter (MWD), geometric mean diameter (GMD), and erodibility factor (K) were calculated.本研究的样本采集自中国武汉某河流旅游公司所辖河岸带的3个代表性样点（五台闸，WTZ；活水公园，HSP；三岔口，SCK），上述样点可反映该河岸带内不同类型的城市活动。研究测定了不同空间位置（采样点、坡位及土壤深度）下的土壤理化性质，随后计算得到土壤团聚体稳定性相关指标，包括平均重量直径（mean weight diameter, MWD）、几何平均直径（geometric mean diameter, GMD）与可蚀性因子（erodibility factor, K）。
