In areas with frequent fires and erosive soils under monsoon climate, we aimed to determine the long-term dynamics of soil loss during vegetation recovery and to examine elapsed time for soil stabilization. Runoff plots were installed in Pinus densiflora forests affected by stand-replacing fires on the East Coast of South Korea, which occurred in spring 2000. Runoff plots measured runoff and sediment yields for 11 years (2003–2013) during which time, vegetation cover of low-, intermediate-, and high-vegetation cover plots increased from 21 to 44%, 49% to 69%, and 87% to 95%, respectively. Vegetation was effective in preventing runoff and sediment yield. Nevertheless, to stabilize to below baseline load, it took 7 years at low and intermediate cover plots and only 3 years at high cover plots. For 7 years, 7.06 (5.2-fold) and 4.29 (3.1-fold) kg m⁻² of soil were lost at the low and intermediate cover plots, respectively, compared to the high cover plots (1.37 kg m⁻²). Sediment loss fluctuated more than runoff following extreme rainfall events. We suggest that for the slow recovery area (< 70% cover), appropriate measures should be introduced to prevent soil erosion immediately after a fire, and logging should be postponed until the soil is stabilized for 3 years even in fast recovery areas (> 70% cover).

在季风气候下经常发生火灾和侵蚀性土壤的地区，我们旨在确定植被恢复过程中土壤流失的长期动态，并研究土壤稳定所需的时间。径流小区安装在松果树上2000年春季在韩国东海岸遭受林分替换林火灾的森林。径流图测量了11年（2003-2013年）的径流和沉积物产量，在此期间，低，中，高植被覆盖度植被覆盖率分别从21％增至44％，49％增至69％，87％增至95％。植被有效地防止了径流和沉积物的产生。但是，要稳定到低于基准负荷，在低和中覆盖地块要花7年，而在高覆盖地块只需要3年。与高覆盖区（1.37 kg m ^-2）相比，在7年中，低覆盖区和中覆盖区分别损失了7.06（5.2倍）和4.29（3.1倍）kg m ^-2的土壤）。在极端降雨事件之后，泥沙损失的波动大于径流。我们建议对于缓慢恢复的地区（覆盖率<70％），应采取适当措施防止火灾后立即侵蚀土壤，并且即使在快速恢复的地区（> 70）也应推迟伐木直到土壤稳定3年。 ％覆盖率）。
