证实了入侵种环境生态位在原产地和入侵地的保守性，构建了基于生态位理论的生物入侵研究框架，明确了全球入侵鱼类的特定生活史对策。
Direction of Mechanisms underlying Invasions:
- Confirming the conservatism of environmental niche between native and introduced ranges for invasive species;
- Developing the framework of studying biological invasions based on niche theory;
- Elucidating the life history strategies of invasive fish species at the global scale.

优化了入侵风险的预测框架以及放生风险的评估指标，预测了鱼类的入侵风险格局，解析了模型的预测能力，确定了优先管理的外来水生生物。
Direction of Predicting Invasion Risks:
- Optimizing the framework of predicting invasion risks, and predicting the geographical patterns of invasion risk of fish species in China
- Developing the indicators of assessing release risks, and identifying alien aquatic species to manage;
- Elucidating the predictive capacity of species distribution models.

构建了鱼类分布和经济损失的数据库，揭示了生物入侵造成我国鱼类原有区系格局的崩塌，全面评估了生物入侵对亚洲经济的影响。
Direction of Invasion Impacts:
- Constructing the distribution database of China’s freshwater fish species, and revealing the collapse of China’s fish fauna due to biological invasions;
- Using the InvaCost database, comprehensively assessing the economic impacts of biological invasions in Asia.
