Impact of Different Cutting Intensifies on Soil Physical and Chemical Properties of Low-Quality Forest Stands in Xiaoxing' an Mountains After Reconstruction
A study was conducted to analyze the dynamic change in soil physical and chemical properties of low-quality forest stands in Xiaoxing' an Mountains after the reconstruction of different cutting intensities. Results show that, within the cutting intensity ranging from 22% to 77% , the soil physical properties of sample plots Z1 (22 % ) , Z2(31% ) , Z6 (66% ) and Z7(77% ) were better than those of sample plots Z3(41% ) , Z4(47% ) and Z5(55% ) in the first three years after reconstruction ; while the soil chemical properties of sample plots Z4 and Z5 were better. The soil physical properties of the sample plots were gradually ameliorated with prolonging reconstruction time. The soil chemical properties of the sample plots changed obviously in the first three years after reconstruction, and soil nutrients increased in the first year after reconstruction, and then declined. Soil available nutrients in the sample plots were higher than those in the unthinned stand. Soil physical and chemical properties tended to improve after reconstruction.
