不同混交比例对杉木和马尾松混交林生长特性的影响

Effects of Different Mixing Ratios on Growth Characteristics of Mixed Forests of Cunninghamia lanceolata and Pinus massoniana

为探究不同混交比例对杉木和马尾松混交林生长特性的影响,以贵州某林场为研究地点,分析了不同混交比例对杉木和马尾松混交林生长特性的影响。结果表明,混交比例对杉木和马尾松的生长指标和生物量分布有显著影响。相对较高的杉木比例可以促进杉木树高和胸径的生长,而相对较高的马尾松比例有利于提高马尾松的树高和胸径的生长。另一方面,相对较低的杉木比例有助于提高杉木各部位及整株的生物量,较低的马尾松比例有利于提高马尾松各部位及整株的生物量。未来的研究可以进一步探讨不同混交比例对其他林木物理和化学特性的影响,以提供更加科学的指导和决策支持。

In order to explore the effects of different mixing ratios on the growth characteristics of mixed forests of Cunninghamia lanceolata and Pinus massoniana,a forest farm in Guizhou Province was taken as the research site to analyze the effects of different mixing ratios on the growth characteristics of mixed forests of Cunninghamia lanceolata and Pinus massoniana.The results showed that the mixed ratio had significant effects on the growth index and biomass distribution of Cunninghamia lanceolata and Pinus massoniana.Future studies can further explore the effects of different mixing ratios on the physical and chemical characteristics of other trees to provide more scientific guidance and decision support.
