Abstract: Advances on the functional response of Herbivorous mammal foraging and the set of plant availability variables were review The biomass density．plant density，and plant size of availability plant and bite size were。potential set of variables influencing the functional response of herbivores foraging，and the differences of the variables lead to complicate pattern of functional response Biomass density and plant density had an insignificant influence oil herbivores intake rate While plant size had a significant effect on intake rate By means of the bite size of herbivore replacing plant size in food-concentrated patches．The intake rate of herbivores could be validly predicted in food-concentrated patches．and the intake rate are an as asymptotic function of bite size．which belongs to type II functional response Under natural conditions，recent studies had focused on separating the main factors which could effect on intake Fates from the set of plant availability Variables by experiments.
