底栖动物增殖放流生态风险评价

Construction of ecological risk assessment system for stock enhancement in zoobenthos

为了评价底栖动物增殖放流过程中存在的生态风险,通过现场调查、已有文献资料分析和专家咨询,建立了以层次分析法为基础的生态风险评价体系。应用该体系对5种增殖放流的底栖动物进行了生态风险评价。研究表明,西施舌、紫海胆、韩国文蛤和泥东风螺为"中"风险等级;波纹巴非蛤为"低"风险等级。本研究可为今后增殖放流过程中的生态风险评价提供参考。

To assess the ecological risk of stock enhancement, an ecological risk assessment（ERA） system was constructed based on the analysis of the past literatures, field survey and expert consultancy. The system constructed using analytic hierarchy process（AHP） method was applied to 5 zoobenthos. The results showed that：the risk grade of Coelomactra Antiquata, Anthocidaris crassispina, Meretrix lamarckii, Babylonia lutosa was medium, and that of Paphia undulate was low. The construction of this risk assessment system will provide beneficial suggestions in the future stock enhancement.
