摘　　要：通过对福寿螺生态风险较全面的分析,认为福寿螺不仅会对水稻产生直接的危害,而且会对水生生态系统的生物多样性和水体环境造成直接和潜在的危害。同时,福寿螺在特定空间和时间内具有种群暴发的风险以及向我国长江以北地区继续迁移与扩散的风险。在此基础上,进一步提出了有关福寿螺入侵的生态风险评估的概念框架。该研究结果可为控制与预防福寿螺的危害发生提供相关科学依据与参考。An analysis of the ecological risks of golden apple snails shows that such snails are harmful to rice growth and have direct and potential effects on aquatic biodiversity and water quality.Golden apple snails are likely to burst into a sudden growth in some specific locations and periods and expand northward with a dispersal risk in China.A conceptual frame for ecological risk assessment on the invasion of golden apple snails was presented.The analysis and the assessment are expected to help provide some scientific guides and references for the controlling and preventing golden apple snail from invasion.
