摘　　要：竹柏种源在福建延平峡阳、漳平金水、宁德直洋、莆田东圳的造林对比试验结果表明:12年生时竹柏种源地径生长性状有明显差异;竹柏主要经济性状具有明显的年度、种源和环境效应,3个主要经济性状(单位面积产量、千粒质量、种子含油率)在种源、不同试验点间均存在极显著或显著差异;依据种源主要经济性状进行系统聚类分析,将其划分为4类,其中Ⅰ类种源A2(福建延平)、A7(江西婺源)为最优种源。The forestation contrast tests on Podocarpus nagi provenances from Xiayang distract of Yanping county, Jinshui of Zhangping, Zhiyang of Ningde, Dongzhen of Putian in Fujian province were conducted. The testing results show that among the 12-yearold of P. nagi provenances there were significant differences in ground diameter＇s growth traits; the main economic characters of P. nagihad obvious annual, provenance and environment effects;three major economic characters（per unit area yield, thousand kernels mass and seed oil content） had extremely significant or significant differences among the provenances and the different testing sites; according to the main economic traits of provenances, the hierarchical cluster analysis was carried out, the P. nagi provenances were divided into four categories, of them, the I-type provenance was the optimal provenances, which include A2（Fujian Yanping）and A7（Jiangxi Wuyuan）.
