DEMOGRAPHIC METHOD FOR THE CALCULATION OF THE PRODUCTION OF AQUATIC PLANT

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.
