在日本冈山县备前市久久井地区的一片森林火烧迹地,布设了3块不同样地进行调查取样和室内实验对比分析。对火烧后由于降雨所引起的土壤理化性质的动态变化进行了数据分析。结果表明,3块样地土壤的pH值、物理性质以及养分的流失程度均不同。根据研究结果,探讨了减少土壤养分流失的方法,从而选择最适植被恢复方式,为火烧迹地的植被恢复提供理论依据。 In a scene of forest fire in the area of ​​Keikui, Keio-ku, Okayama Prefecture, Japan, three different sample sites were set up to conduct survey sampling and laboratory experiments. The data analysis of the dynamic change of soil physical and chemical properties caused by rainfall after fire was carried out. The results showed that the soil pH value, physical properties and nutrient loss were different in three plots. According to the results of the study, the methods of reducing soil nutrient loss were discussed, and the optimal vegetation restoration method was selected to provide the theoretical basis for vegetation restoration in the burned-out area.
