Abstract This research aimed to estimate the splash erosion and its evolution during the first months in specific land uses after a forest fire. The study area was located in Congosto (North-West Spain), after a wildfire occurred in May 2012, which burned 15.56 ha of scrubland and Pinus reforestation. Two different burned land uses were selected and compared to control areas: i) burned pine forest; and, scrublands. Rainfall intensity and the number, sizes and speed of raindrops were measured by an optical disdrometer and soil loss by funnels. Moreover, infiltration, soil moisture content, aggregate stability, water repellence, pH and organic matter were also measured. Results showed that the highest soil losses occurred in the burned areas, especially in the scrubland plots. The most influential factors were the presence of bare soil and the very low vegetation recovery rate. Changes in soil properties did not significantly influence splash erosion, although an increase in the presence of smaller classes of aggregates could promote erosion in the scrubland. We conclude that the vegetation ecosystem restoration is the key issue to be considered after a wildfire, especially, in those types of land uses which are severely affected by the fire.

确定火灾和不同土地用途对飞溅侵蚀的潜在影响

摘要 本研究旨在估计森林火灾后特定土地用途最初几个月的飞溅侵蚀及其演变。研究区位于康斯托（西班牙西北部），2012 年 5 月发生野火，烧毁了 15.56 公顷的灌木丛和松树再造林。选择了两种不同的烧毁土地用途并与对照区域进行比较：i) 烧毁的松林；和，灌木丛。降雨强度和雨滴的数量、大小和速度通过光学偏差计测量，土壤流失通过漏斗测量。此外，还测量了入渗、土壤含水量、团聚体稳定性、防水性、pH 值和有机质。结果表明，烧毁地区的土壤流失量最大，尤其是灌木丛地块。影响最大的因素是裸土的存在和非常低的植被恢复率。土壤性质的变化并没有显着影响飞溅侵蚀，尽管较小类别聚集体的增加可能会促进灌木丛的侵蚀。我们得出结论，植被生态系统的恢复是野火后需要考虑的关键问题，特别是在那些受火灾影响严重的土地利用类型中。
