摘　　要：本研究通过样方调查法对飞播马尾松低效稀疏林、马尾松混交低效稀疏林和人工松类低效林等8种林地补植改造,并进行苗木成活率、平均高生长量、植被覆盖度和平均地径增量的测定,以检验低质低效林改造成效。结果表明,不同类型低质低效林补植改造的苗木成活率、平均高生长量、植被覆盖度和平均地径增量等主要评价因子数据较好,达到了预期的效果,以人工杉木低效林和天然阔叶残次林上的补植改造效果较佳,为低质低效林分的改造与林分质量的提高提供参考。A plot survey method was used to measure the survival rate,average height growth,vegetation coverage,and average ground diameter increment of seedlings in eight types of replanting and transformed forest land,including low efficiency sparse forests of Pinus massoniana,mixed low efficiency sparse forests of Pinus massoniana,and low efficiency forests of artificial pine species,in order to test the effectiveness of low quality and low efficiency forest transformation.The results showed that the main evaluation factors for the replanting and transformation of different types of low quality and low efficiency forests,such as survival rate,average height growth of seedlings,vegetation coverage,and average ground diameter increment of seedlings,were good and achieved the expected results.The transformation effects were better on artificial low efficiency Chinese fir forests and natural broad-leaved residual forests,providing references for the replanting and transformation of low quality and low efficiency forest stands and the improvement of stand quality.
