| 摘 要： | 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.

| Abstract: | Three different plots in the burned the dynamic changes of soil chemical and ph forest area at Okayama, Japan were constructed to investigate ysical properties and soil nutrients caused by rainfall. It was found that the pH values, physical properties, and soil loss from the three plots were different. By referring to the domestic and international research results, the best way of reducing soil nutrient loss was found for a suitable approach to vegetation recovery. |
