海水增养殖区生态风险评价方法研究

Study on ecological risk evaluation method of mariculture zones

海水养殖在促进经济社会发展的同时也带来了一系列生态环境问题。针对我国海水养殖规模巨大及海水养殖生态环境压力突出等问题,为客观评价我国海水增养殖区面临的生态风险,本文基于养殖生物能否被养成和养殖产品能否安全食用的理念,综合考虑海水增养殖区环境质量风险、养殖产品食用安全风险、病害发生风险和赤潮发生风险四个方面,构建了海水增养殖区生态风险指数评价方法。该方法将海水增养殖区评价从环境角度拓展至生态环境角度,为我国海水增养殖区评价方法体系提供有益补充,评价结论可为我国海水增养殖区生态风险管控提供支撑。

While promoting economic and social development,mariculture also brings a series of ecological and environmental problems.In view of the huge scale of mariculture and the prominent ecological and environmental problems of mariculture in China,in order to objectively evaluate the ecological risk faced by mariculture zones in China,based on the concept of whether cultured organisms can be cultivated and whether cultured products can be eaten safely,this paper constructs an ecological risk index evaluation method of mariculture zones by comprehensively considering the environmental quality risk,food safety risk,disease risk and red tide risk.This method extends the evaluation of mariculture zones from the environmental point of view to the ecological environment point,and provides a useful supplement for the evaluation method system of mariculture zones in China.The evaluation conclusion can provide support for the ecological risk control of mariculture zones in China.
