| 摘 要： | 预防生物入侵的一个重要手段是对外来物种进行风险评估，应用模型则是定量评估的必备方法。本文简述了常用的适生性风险评估模型，概述了诸如遗传算法、模糊包络模型、自组织特征映射网络等较新的理论方法，它们使用环境变量和物种实际分布数据，利用不同的机理模型预测物种潜在分布区。本文还综述了适用于研究物种扩散性的模型，积分差分方程模型可以模拟物种扩散行为，元胞自动机模型可以揭示种间竞争关系，景观中性模型大多用于种群动态等生态过程的研究。

| Abstract: | 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. |
