摘　　要：青钱柳是我国特有的珍稀多用途树种。以浙江千岛湖林道边6m间距的33a生青钱柳人工林为研究对象,通过树干解析和生物量测定,研究其生长过程和生物生产力特征。结果表明:1)青钱柳生长快,树高速生期3—14a,胸径速生期4—19a,材积速生期7—24a;树高持续保持良好生长,24 a进入数量成熟期,其生长趋势离经济成熟、工艺成熟、自然成熟还有较长时间。2)33a生青钱柳10月份的树木各器官的含水率大小趋势为叶>根>枝>干>果,在10月初落叶时青钱柳的叶含水率仍达60%以上,可以常年用叶做茶制药。树木各器官的生物量比重大小趋势为干>枝>根>叶>果,干和枝生物量比重分别在46%,36%以上。平均生物量为610.152kg/株。青钱柳枝叶茂盛,根系发达,高大挺拔,生产力高,有一定的林下更新能力,开发利用前景广阔。Cyc/ocarya paliurus is unique rare and multi-purpose tree species in our country. Taking the 33a and 6m spacing Cyclocarya paliurus planted forest as the study object,growth regularity and biomass productivity were discussed by trunk parsing and biomass measurement. The results showed that, 1) Cyclocarya paliurus grew fast and its fast growing period of height was 3 to 14a,fast growing period of DBH was 4 to 19a,fast growing period of volume was 7 to 24a. Quantity maturity was after 24a and it was not to mature in economy, quality and in nature. 2) The trend of moisture content of 33a Cyclocarya paliurus was leaf > root > branch > stem > fruit. The moisture content of Cyclocarya paliurus leaf was above 6 0 % and can be perennially made as tea and pharmacy. The biomass proportion of organs showed stem >branch > root > leaf > fruit with stem and branch above 4 6 % and 3 6 % . The average biomass was 610.152kg per plant. Cyclocarya paliurus has broad prospect in development.
