在福建将乐林场,采用标准样地法调查栲类次生林标准地(P_1~P_(10)号样地)天然更新数据,采用熵值法从分布状况、生长状况方面构建栲类次生林更新的评价指标体系,研究栲类次生林林分更新状况及栲类树种苗木更新状况。结果表明:各标准地林分更新层更新综合值大小排序为P_(10)(0.732)>P_1(0.714)>P_3(0.678)>P_8(0.638)>P_4(0.614)>P_5(0.564)>P_2(0.557)>P_7(0.556)>P_6(0.541)>P_9(0.474);栲类树种幼苗更新综合值排序为P_3(0.904)>P_8(0.854)>P_2(0.799)>P_7(0.782)>P_6(0.725)>P_(10)(0.697)>P_5(0.669)>P_9(0.650)>P_4(0.497)>P_1(0.411)。综合分析,栲类幼苗的更新综合值最大的为P_3标准地,而在更新层的总体水平中处于中上水平,若加强辅助经营管护措施,最有可能形成较为稳定的栲类次生林群落。
The natural regeneration data of 栲-type secondary forest (P_1-P_ (10)) were investigated using standard plots in Fujian Leqiang Farm, and the evaluation of secondary forest renewal was constructed from the aspects of distribution and growth using entropy method Index system, research 栲 secondary forest stand regeneration status and 栲 species tree seedling update status. The results showed that the order of update integrated value of the updated layer of the standard stands was P_ (10) 0.732> P_1 0.714> P_3 0.678 P 0.6 0.664 P_5 0.664 P_5 0.564 P_2 (0.557)> P_7 (0.556)> P_6 (0.541)> P_9 (0.474). The updated integrated values of seedlings of 栲 species were P_3 (0.904)> P_8 (0.854)> P_2 (0.799)> P_7 (0.782)> P_6 0.725 P_10 0.697 P_5 0.669 P_9 0.650 P_4 0.497 P_1 0.411. According to the comprehensive analysis, the most comprehensive update value of 栲 seedlings is P_3 standard, while it is in the middle and upper level in the overall level of the updated layer. If secondary management and management measures are strengthened, it is most likely to form a relatively stable 栲 secondary forest community.
