摘　　要：通过对４５年生的赤桉、邓恩桉、多枝桉等３种类１１种源的种类种源试验林的生长调查、形质指标调查和造林保存率的调查，采用单因素方差分析和多目标决策理论等综合分析评定方法，来评判种源的优劣。研究结果表明：到目前试验研究阶段，仍以赤桉１５０２５、１５０２２和贵溪赤桉为最佳种源。多枝按１５２１３、邓恩桉１７３３３和祁阳赤桉为淘汰种源。在资兴市或类似资兴市气候的湘南各县（市）可以对赤桉１５０２５、１５０２２和贵溪赤桉进行中试扩大栽培试验。Growth,morphological index and survival rate in 11-half and four-year-old forest of provenance trails from 3 species of Eucalyptus, E.Camaldulensis,E.dunnil and E.viminulis, were investigated.By means of analysis of variance,multiple objective determination principle and other complex analysis methods,the differences among the provenances were compared.The result shown that E.TBXcamaldulensis No.15025 and No.15022 and Guixi cucalyptus were the best provenance,which can be cultivated in those places whose climate is similar to that of Zhixin city.While E.viminalis 15213,E.dunnil 17333 and Qiyang Eucalyptus should be discarded.
