Being developed through over one hundred years,there has been much progress in the field of the population dynamic model.In this paper,a review of its achievements was given as well as a looking forward to its future developments.Population dynamic includes quantitative dynamic and spatial-temporal distribution dynamic.According to the form and research content,the population dynamic models can be divided into mathematic models and spatial models.The mathematic models simulate the population fluctuations by mathematical equations,such as J growth model,S growth model and Lotka-Voltera model,etc.Spatial models focus on spatial pattern of population and habitat,such as Metapopulation Model,Spatially Explicit Population Model and Individual-Based Models.Population dynamic models have been successfully applied in species protection,climate change and land management.Presently population dynamic models are short in spatial information expression,and it is considered that combining with geographic information technology is the trend of population dynamic model.
