根据我国大兴安岭地区森林火灾频繁发生、火烧迹地面积逐渐扩大的实际情况,在日本冈山县备前市久久井地区的一片森林火烧迹地,设立3块不同样地进行调查研究,对火烧后由于降雨引起的水分及土壤养分的动态变化进行分析,发现3块样地水分和土壤养分的流失程度不同,同时参照国内外其他地区的研究结果,寻求减少土壤养分流失的最佳方法,从而选择最适植被恢复方式,为我国大兴安岭地区火烧迹地的植被恢复提供理论依据。 According to the fact that the forest fire frequently occurs in Daxinganling area of ​​our country and the burned area gradually expands, three different plots were set up in the burned-out area of ​​a long time in the area of ​​Kejiuqian, Ke Qian, Okayama Prefecture, Japan. The results showed that there was a difference in the degree of soil water loss and soil nutrient loss in the three plots, and the best method to reduce soil nutrient loss was found with reference to the research results in other regions at home and abroad, so as to select the optimum The method of vegetation restoration provides a theoretical basis for vegetation restoration in the Daxinganling area in China.
