Application of System Dynamic Modeling Software in the Population Ecology

QING Zhong et al (College of Agronomy,South China Agricultural University,Guangzhou,Guangdong 510642)  
STELLA software was introduced in the study of population ecology.Taking Logistic model and Lotka-Volterra model as an example,the characteristics of this software were introduced,and the process and procedure of model establishment were expatiated.Meanwhile,the operation result of the model was showed visually by figures,and then,they were analyzed.Research showed that STELLA was a viable approach which allowed establishing conceptual model for a better insight into environmental and ecological processes and solving the complex problems associated.And furthermore,it could be used to predict the trend or behavior of a certain ecosystem under different scenarios.This software might be advocated and applied widely in future research of ecology.
