- Abstract:
- Freeze-thaw is intense in the spring thaw period, soil erosion and phosphorus migration always happen frequently. In this study, rainfall simulation experiment was carried out on the slopes with different phosphorus (P) background values during the spring thaw period to study the dynamic processes of runoff, sediment yield and loss of P. The results showed that in the first 14 min, runoff and sediment presented the good linear distribution, the coefficients of correlation of runoff and sediment yield were 0.969 and 0.936, respectively, and then increased slowly in 14~18 min, runoff maintained its quantity of 3 100 ml/min until the end, while sediment yield generally increased first and then decreased. The higher soil background values are (APb), the higher concentrations of P are in the runoff and sediment; the average ratio of P loss of the APb20 slope was the largest in runoff, and showed a decrease trend with the increase of APb value; while the average rate of P loss of APb40 slope was minimum, and there were little differences between other slopes; P in runoff and sediment had good linear relationship, and the fitting equation is y=6.751x-0.628 (R2 =0.958).
