Abstract

A field experiment in the Shangnan County using small erosion plots was carried out to determine and compare the soil loss and surface runoff from 5 vegetation covers and 3 levels of slope gradient. The 5 vegetation covers embraced the most frequent rural land-use forms in the study area : farmlands including horticulture (tea plantation with peanut as an intercrop) and agriculture (maize in a winter-wheat–summer-maize rotation) activities, grasslands that have developed on abandoned farmlands, and forestlands including low and high forests (Chinese cork-oak coppices and pine plantations, respectively). The change in the runoff among the vegetation covers and slope gradients was high but not as significantly pronounced as for the change in the soil loss. Results showed that the slope gradient has an impact on the runoff and soil loss. In addition, results exhibited that the rate of erosion is substantially affected by changes in vegetation cover
