不同采伐剩余物处理对杉木生长及土壤理化性质的影响

Effect of Different Logging Residue Clearances on the Growth and Soil Physical-chemical Properties of Chinese fir Forest

该文分析了采伐剩余物带状清理、全部移除以及炼山等不同采伐剩余物处理方式对杉木林生长以及土壤理化性质的影响。研究结果表明,采伐剩余物带状清理方式在提高杉木林的生长量以及改良土壤理化性质的能力方面均优于炼山处理,而采伐剩余物全部移除方式改良土壤的能力最差。建议今后采伐迹地采伐剩余物采用带状清理方式,从而实现杉木林的可持续经营。

Chinese fir is one of the most important timber tree species in southern China. Clean-banded logging residue, remove logging residue and controlled burning cleaned logging residue were used to analyze the effect of different logging residue clearances on the growth and soil physical-chemical properties of Chinese fir forest in this paper. The results showed that： Clean-banded logging residue had the better effect on growth and soil physical-chemical properties of Chinese fir forest than that of the controlled burning cleaned logging residue, and remove logging residue was the worst; using clean-banded logging residue to clear logging residue was suggested, so as to realize the sustainable management of Chinese fir forest.
