“…Some researchers simulated the soil erosion in different situations, thus expanding the application of the empirical models (Han, Ren, Zhang, & Li, 2016; Hessel, Messing, Chen, Ritsema, & Stolte, 2003; Zhou, Shangguan, & Zhao, 2006). Field observation included the use of data on river run‐off, sediment content, and sediment transport obtained from published data or experiments seeking to analyse the impact of GFG on soil erosion in specific areas, especially at the river basin scale, and these were all used to make suggestions for feasible measures (Deng et al, 2019; Gao, Fu, Zhang, Ma, & Sivapalan, 2018; Yang et al, 2018). In addition, although some studies used empirical models to calculate the soil erosion, they also verified the empirical models through experimental observations, thus ensuring the reliability of the empirical model results (Jiang, Zhang, Wang, Feng, & Labzovskii, 2019; Jiang, Zhang, Zhang, & Wang, 2019; Sun, Shao, Liu, & Zhai, 2014).…”
