摘　　要：针对会东县人工华山松成过熟低效林分布海拔高、环境条件差、林分郁闭度大、林木枯死枯梢率高、生长严重衰退、基本丧失结实能力,且天然更新不良的情况,提出了宜采取“择伐促进天然更新+林下人工促更+定株培育”的“近自然育林”改培方式进行改造。In this area,the overripe and low-efficiency artificial Pine forest of Huashan mountain has high altitude distribution,poor environmental conditions,large stand canopy density,high tree mortality rate,serious growth decline,basic loss of fruiting ability,and poor natural regeneration.The transformation should adopt the"near natural forest cultivation"method of"selective cutting promotes natural regeneration+artificial promotion under the forest+fixed plant cultivation".
