Abstract:: The natural polymer derivative Jag C162 is a new type of polymer. Studying the impact of the polymer on the runoff process of loess slopes can provide a new theoretical basis for the chemical regulation of soil erosion on loess slopes. The purpose of this study is to explore the regulatory effect of Jag C162 on soil properties and runoff processes. The effect of Jag C162 on the runoff processes was studied under three rainfall intensities(1, 1.5, 2 mm/min), three slope gradients(10°, 15°, 20°), and four rates(0, 1, 3, 5 g/m²)based on indoor artificial simulated rainfall experiments. The results show that:(1)the runoff onsets of 1 g/m²and 3 g/m² Jag C162 were significantly lagging behind that of bare slope(p<0.05), while the runoff onset was significantly earlier for 5 g/m² Jag C162(p<0.05);(2)runoff rates increased rapidly and then tended to a slow increase under different rates of Jag C162; the runoff rates of different rates of Jag C162 decreased in the order: 0 g/m²>1 g/m²>5 g/m² >3 g/m²;(3)for all three rates, Jag C162 could improve the contents of >0.25 mm soil water-stable aggregates significantly, also for different sizes of aggregates; in particular, the contents of aggregates of 1～2 mm, 2～5 mm, and >5 mm increased greatly with increased rates. Therefore, Jag C162 could significantly improve soil aggregate structure, improve soil infiltration performance, reduce surface runoff, and weaken the runoff dynamics of erosion, so as to achieve the purpose of soil erosion control.
