摘　　要：目的:探讨一种便于五味子资源产量和蕴藏量统计估算的新方法,并准确得出五味子果实可利用生物量回归方程。方法:采用实地样方调查、相关生物量数据测定和统计分析相结合的方法。结果:单一果穗重量与果穗长度、宽度和小浆果数量的多元线性回归方程为:Y=-12.66+0.1X1+0.489X2+0.265X3。结论:所得回归方程理论上可准确估算五味子果实可利用生物量,这一方法也可应用于其它聚合果和小浆果类药用植物资源调查中。Objective： To explore a new method of statistics in production and reserves of resources Schisandra chinensis （Turcz.） Baill. , and accurately obtain regression equation of available biomass of Schisandra chinensis. Methods： Field samples investigation, relative biomass data determination and sta- tistical analysis were employed. Results： A multiple linear regression equation of ear weight, ear length, width and numbers of small berries was Y= - 12.66 ＋0. 1X1 ＋0. 489X2 ＋0. 265X3. Conclusion： Theo- retically, the available biomass of Schisandra chinensis could be accurately estimated by a multiple linear regression equation. The method could be used in other medicinal plants resources investigation of aggre- gate fruits and small berries.
