水生动物外来物种入侵风险评估系统的建立

Risk assessment system for alien aquatic animals

通过对我国水生动物外来物种入侵现状分析,提出对其风险评估的重要性、必要性以及应用的前景.考虑到建立风险评估系统的复杂性,通过水生动物生境模拟实验模型,获取评估对象的繁殖力、竞争力和生存力指标,结合环境监测等数据,建立我国水生动物外来物种信息数据库,并将外来物种分为肉食性物种、杂食性物种和适生区物种三个大类,分别建立名录检索、引入文献数据检索和专家名录检索等相关检索,结合计算机技术,初步确定入侵风险评估的具体指标,构建了一个具体可行的水生动物外来物种入侵风险评估系统.

In this paper, the situation of biological invasion in China was described, and the importance, necessity, and the future application of risk assessment system for biological invasion were lodged. As the risk assessment system is quite complex, we establish an environmental simulation model for aquatic animals to obtain their data of reproduction, competition and survival ability. With the data from environmental monitor, the database for the alien aquatic animal information has been set up, and the alien animals are classed to 3 kinds, and the query method for them were set up. Combined with computer technology, preliminary data index for invasion risk assessment were decided, and a feasible risk assessment for aquatic animals＇ invasion was set up.
