- Abstract:
- Rock fragment, a sign of soil degradation and ecosystems degradation, is the results of a variety of hydrologic and erosion processes. Conversely, the rock fragment also has effect on erosion processes. The relationship between rock fragment cover and weight percentage was studied according to the data of rock fragment and rock fragment weight percentage at different depths (0-2, 2-5, 5-10, 10-15, 15-20 cm). The results show that the linear correlation coefficient between rock fragment cover and weight percentage increased with the decrease of soil depth. The relationship between rock fragment cover and weight percentage with large-size (6～20 mm, 20～60 mm) was more significant than those with small-size (2～6 mm). When the particle size is greater than 2 mm, the rock fragment cover significantly positively correlated with weight percentage.
