水生植物生产量测定的种群统计学方法

DEMOGRAPHIC METHOD FOR THE CALCULATION OF THE PRODUCTION OF AQUATIC PLANT

以Ａｌｅｎ曲线法为例，介绍了水生植物生产量测定的种群统计学方法的原理，并以同龄群的指数增长与死亡模型为基础，得出了同龄群生产量的计算公式。以湖北斧头湖菰群落的调查数据为例计算了菰的生产量。

The principal of the demographic method for the calculation of the production of aquatic plant was briefly introduced in this paper with Allen curve as an example,and the calculation formula of the production of a cohort was obtained based on its exponential models of growth and death.The production of Zizania latifolia (Griseb.)Stapf in Futouhu Lake,Hubei Province as an example was calculated using original demographic data of the species.
