摘　　要：在杉木林种植过程中,不同的抚育间伐强度对于杉木林生长具有较大的影响。为了解不同抚育间伐强度对杉木林生长的影响,主要通过开展有效的试验,设定不同的间伐强度来加强3次重复抚育管理。通过分析胸径、蓄积、树高和单株材积等因素对杉木林生长的影响,提升杉木的合理抚育间伐水平,促进林分生长,为后续的林木质量提升提供保障。Different thinning intensities have a significant impact on the growth of Cunninghamia lanceolata(Lamb.)Hook.forests during the planting process.In order to understand the impact of different thinning intensities on the growth ofCunninghamia lanceolata(Lamb.)Hook.forests,this article mainly conducts effective experiments and sets different thinning intensities to strengthen the management of three repeated nurturin,analyze the effects of factors such as diameter at breast height,volume,tree height,and individual volume on the growth of Cunninghamia lanceolata(Lamb.)Hook.forests,in order to improve the reasonable nurturing and thinning level of Cunninghamia lanceolata(Lamb.)Hook.,which can promote stand growth and provide guarantees for the subsequent improvement of forest quality.
