A study was conducted to analyze physical and chemical properties of soil in bumed forestlands of different fire intensities in Huzhong National Nature Reserve of Daxing' an Mountains by comparing with the unbumed 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.
