摘　　要：以大兴安岭地区西部呼中国家级自然保护区2008年受火烧干扰的林分为研究对象,对2个典型林型落叶松林和白桦林不同火烧强度的土壤理化性质进行了分析。结果表明:2个林型在不同火烧强度的作用下,其土壤含水率、土壤密度、pH值、有机质及营养元素质量分数等理化性质表现出显著的差异性。A study was conducted to analyze physical and chemical properties of soil in burned forestlands of different fire intensities in Huzhong National Nature Reserve of Daxing’an Mountains by comparing with the unburned forestlands.Results showed that soil physical and chemical properties,such as soil moisture content,volume weight,pH,and contents of organic matter and nutrient elements,in Larix gmelini and Betula platyphylla forests were various under different fire intensities,and the differences were obvious.
