A New Population Growth Model Based on the Time Dependent Changes of the Specific Growth Rate

Abstract:

A mathematical model, describing the population growth under limited conditions, was developed based on the time dependent changes of the specific growth rate. This model could simulate the lag growth phase, the exponential growth phase and the stationary growth phase of the population growth of many kinds of biology or their organs or cells. This model had less parameters, and all the parameters had clear physiological meanings and were easy to be calculated.

Key words:Mathematical model, Population growth, Specific growth rate
