Data for Use of vector method to evaluate the effect of land use and soil parent material on aggregate stability in red soil zone of Southern China

As the major limiting factor controlling soil erosion, soil aggregate stability may be closely related to land use and soil parent material in the red soil region of southern China. However, relatively few studies have been conducted to comprehensively synthesize the effects of land use and soil parent materials on the stability of soil aggregates. In view of this, in this study, soil samples of four typical land use types (natural forests, artificial forests, orchards, and slope farmland) and two parent materials (granite and slate) were collected from every 20 cm in soil depth 0-100 cm in Dawei Mountain National Forest Park and Xiaoxi National Forest Park, respectively, which are located in the subtropical red soil zone. And soil aggregate stability was determined by a new approach of vector method to calculate the vector length stability index (VLSI) and its weighted form (wVLSI).
