In recent decades, wildfires have become a serious threat worldwide, producing disasters in the natural and anthropogenic environment as well as serious economic losses. One of wildfire’s major impacts is soil erosion, as it may cause major problems in both the physical and anthropogenic environment and seriously affect the landscape. This study investigates the soil erosion rate changes in areas affected by wildfires and uses, as a pilot area, the drainage basin of the Pinios earth-filled dam located in the Ilia Regional Unit, western Greece, which has suffered serious erosion changes after a wildfire event. For this purpose, the Revised Universal Soil Loss Equation (RUSLE) is applied in GIS software, and the soil erosion rate changes in the selected investigation area are estimated at different time intervals. Specifically, soil erosion rate changes are calculated by importing the factors from the RUSLE equation in the GIS software and uses as a dependent variable the cover management factor C, which is strongly influenced by large destructive fires. The models that are produced are compared with each other by collating average annual soil erosion maps and rates before the fire, immediately after the fire and for the existing conditions occurring in the pilot area.

估算受野火影响的地区的土壤侵蚀率变化

在最近几十年中，野火已成为世界范围内的严重威胁，在自然和人为环境中造成灾难，并造成严重的经济损失。野火的主要影响之一是水土流失，因为它可能在物理和人为环境中造成重大问题，并严重影响景观。这项研究调查了受野火影响的地区的土壤侵蚀率变化，并以试点地区位于希腊西部Ilia区域单位的Pinios土坝的流域为例，该地区在经历了野火后遭受了严重的侵蚀变化事件。为此，在GIS软件中应用了经修订的通用土壤流失方程（RUSLE），并以不同的时间间隔估算了所选调查区域的土壤侵蚀率变化。特别，通过从GIS软件中的RUSLE方程中导入因子来计算土壤侵蚀速率的变化，并将其作为因变量使用覆盖管理因子C，该因子受大型破坏性火灾的强烈影响。通过比较平均年土壤侵蚀图和火灾发生前，火灾刚发生后以及试验区域中现有条件的比率，将生成的模型相互比较。
