It is widely acknowledged that risk assessment has become an indispensable part of controlling of biological invasion. Therefore, there is a pressing need to formulate scientifically sound methods and approaches of quantitative model in this emerging field. This paper reviewed a few new predictive modeling techniques, called genetic algorithm, fuzzy envelope model and selforganising map, which are used to predict potential distribution of organisms. Meanwhile, integrodifference equation models, cellular automata and neutral landscape models, which deal with the spread of populations, were also introduced and discussed.
