树参种群在群落中的结构特征及种间关联分析

StructureCharacteristics and Species Association of Dendropanaxdentigerin Communities

    摘要
  • 摘要: 树参Dendropanaxdentiger为阴性树种，适宜在林下培育；作为药食两用型木本蔬菜，在发展林下经济中具有较大的开发潜力。在浙江省庆元县的竹口镇、黄田镇、屏都街道、五大堡乡、荷地镇、张村乡、庆元林场千岗坑林区和百山祖自然保护区8个不同海拔地段，选取具有树参自然分布的8个样地，开展树参种群在群落中的结构特征及种间关联研究。结果表明，在8个样地中，树参的重要值在5.86～11.31之间；在森林群落的结构中居于亚乔木层，其平均树高为6.16m，平均胸径为7.35cm，群落中的优势种通常为木荷Schimasuperba，青冈Cyclobalanopsisglauca，甜槠Castanopsiseyrei等，树参与木荷间呈显著的正关联（t＞t0.05=1.86），而与其他43个树种呈不显著的正或负相关。研究认为，树参作为林下经济植物开发宜选择以木荷为主的常绿阔叶树种，并可伴生杉木Cunninghamialanceolata等针叶树种和枫香树Liquidambar formosana等落叶树种。

     

    Abstract: In Qingyuan county, Zhejiang province, 8 typical sample plots were established for tally at forest distributed with Dendropanaxdentiger.The results showed that the important value of D.dentiger ranged from 5.86 to 11.31 at sample plots.In the communities, it was always the subtree layer, with average height of6.16m, mean DBH of7.35cm.The dominant species in surveyedcommunities wasSchimasuperba, Cyclobalanopsisglauca, Castanopsiseyrein.Analysis demonstrated that there was a significant positive correlation between D.dentiger and S.superba, but no significant positive or negative correlation with other 43 tree species.
