Abstract

The AA. explored changes in soil moisture after 12 precipitation events at 38 sampling locations in the Wulongchi catchment located in the Danjiangkou Reservoir Area in Hubei province, China. The results indicated that variation in soil moisture increased with decreasing soil moisture following each of the 12 precipitation events. Using a two-way indicator species analysis (TWINSPAN), the soil moisture measurement periods following each event were classified into 3 discrete groups : humid periods, moderate periods, and dry periods. For the humid periods, the total variance of soil moisture that could be explained by redundancy analysis was more consistent than those of the moderate and dry periods. For the humid periods on the first axis, soil thickness was the main significant factor, and the topographic wetness index, slope position and aspect were also significant environmental factors. For the moderate and dry periods, however, the effect of aspect on soil moisture decreased, whereas the effect of relative elevation increased
