Abstract: A dynamic model consisting of the rodent and predator is proposed.The quantity equilibrium fomula between rodent and predator in natural ecologic system is deduced .And the formula can be used to show that the numerical and functional responses between rodent and predator are to maintain system's equilibrium.

Key words: nitrogen form, NO3--N, NH4+-N, yield, quality, nutrient absorption.
