Test of the RUSLE and Key Influencing Factors Using GIS and Probability Methods: A Case Study in Nanling National Nature Reserve, South China

Table 7

Influence degree of each factor on four types of soil erosion within the NNNR.

Erosion types	The key influencing factors
	LS	Elevation	Aspect	Slope pattern	K	Lithology	R	Distance to drainage net	Wind speed	C
a. Rill erosion
b. Sheet erosion
c. Gully erosion
d. Human-induced erosion

The asterisk refers to the influence degree of each factor on different types of soil erosion. For a CF value of <0.2, the probability of soil erosion and its influence degree is low (); for a CF value of 0.2–0.4, the probability of soil erosion and its influence degree is moderate (); for a CF value of 0.4–0.6, the probability of soil erosion and its influence degree is high (); and for a CF value >0.6, the probability of soil erosion and its influence degree is very high ().
