摘要:
<正>针对湿地松的生长特性,在8年、12年、16年生湿地松人工林中布设不同间伐强度试验林,研究间伐对林木生长质量的影响。结果表明:间伐对林木生长和林分质量具有一定的促进作用,其中对幼龄林的促进作用明显大于中龄林;随着间伐强度增大,较大径阶立木株数比例随之增加;湿地松人工林首次间伐宜在12年生之前进行,保留900~1100株/hm2。两次间伐的间隔期以8年左右为宜;以培育大中径材为目标的大龄林分应以弱度调整为主,保留600株/hm2。
Abstract:
Through applying different kinds of thinning intensities for the existing typical (Pinus) elliottii forests with 8,12 and 16 years old according to the sites and managements in Anhui and through analysing the timber production,organisms,timber properties,input and output,it was shown that thinning encouraged somehow the growth of stands more to younger stands to mid-aged one;the bigger size trees were increasing as the thinning intensities.The first thinning after 10~12 years while remaining trees 900~1?100?per hm~2.The suitable thinning interval could be 8 years.It is studied that the gentle thinning was applied to train bigger size timber forest with existing trees 600?per hm~2 for the Pinus elliottii.
