速生五金木柄原料林树种评价体系构建与应用

根据五金木柄加工的特殊要求，选取对原料树种有重要影响的产量特性、适应性、造林特性和木材材性的四大类9个指标，利用层次分析法确定指标权重，建立综合评价体系，对所选16个树种（无性系）进行优选评价。结果表明，胸径生长量、树高生长量、立地要求、萌芽更新能力和木材材性等5个指标相对于其他指标占有较大权重，是影响目标选择的主要因子。鹅掌楸Liriodendron chinense和黄山栾树Koelreuteria bipinnata var. integrifoliola综合评价最好，无患子Sapindus mukorossi和青冈Cyclobalanopsis glauca综合评价最差。根据综合评价结果，结合树种特性和目前的推广应用情况，建议选择鹅掌楸，喜树Camptotheca acuminata，小果冬青Ilex micrococca，二道柳Salix spp. ，枫香Liquidambar formosana和木荷Schima superba等作为当前浙中地区速生木柄原料林主要造林树种，因地制宜进行首批推广。图1表4参28

Establishment and application of tree species assessment system on fast-growing handle making raw material forests

Based on the special requirements for the wooden handle processing,9 indexes of 4 categories affecting raw material species,namely,output characteristic,adaptability,afforestation features and timber properties were used to determine the weight ofindexes and build a comprehensive assessment system for the selected 16 cloned tree species through an analytic hierarchy process.The results indicated that DBH and height growth,site requirements,sprout ability and timber properties were main factors affecting target selection.The species with the best comprehensive performance were Liriodendron chinense and Koelreuteria bipinnata var.integrifoliola,the worst were Sapindus mukorossi and Cyclobalanopsis glauca.According to the assessment results,the tree species characteristics,and the recent applications of the tree species in middle Zhejiang,it was suggested that Liriodendron chinense,Camptotheca acuminata,Ilex micrococca,Salix spp.,Liquidambar formosana and Schima superba could be used as the main tree species for the fastgrowing handle making material plantation in middle Zhejiang and extended first according to the local conditions.
