摘要/Abstract

摘要： 近年来,我国海水网箱养殖业的迅速发展给海洋生态环境带来了相当大的压力。目前不少学者从不同方面对网箱养殖区环境质量作了分析和评价,但还没有1个公认统一的评价标准和方法,也缺乏从整体上进行综合评价的研究。本文以宁波西沪港网箱养殖区为例,采用层次分析法,从环境适宜性和水产品质量安全性两方面构建了网箱养殖区环境质量综合评价指标体系,根据历史和现状监测资料以及相关文献筛选了评价指标,确定了评价标准,并结合指数评价法对养殖区环境质量现状进行了综合评价。评价结果表明:2011年西沪港网箱养殖区综合质量等级为较好,主要存在的风险为水体富营养化和水产品中的重金属污染。

Abstract: The rapid development of cage culture has brought high pressure to the marine ecological environment in recent years. Although the environmental quality of cage culture area has been analysed and evaluated at different aspects by scholars, there is lack of universally accepted evaluation criterias and methods, and integrated assessment in these researches. In this study, by using analytic hierarchy process(AHP), a comprehensive indicator system for environmental quality evaluation of cage culture area was constructed from two aspects: the environmental suitability, the quality and safety of aquatic products. Based on the historical and current monitoring data of cage culture area in the Xihu Bay, Ningbo City, along with related literatures, the evaluating indicators were selected, and the evaluation criterias were determined. Combined with the index evaluation, these indicators were applied to evaluate the environmental quality of cage culture area in the Xihu Bay. The evaluation results show that the comprehensive quality of the cage culture area in the Xihu Bay in 2011 was rated as ‘comparatively good’, and the main risks identified were eutrophication and the heavy metal pollution in aquatic products.

Key words: cage culture, integrated evaluation, AHP, index evaluation, quality security of aquatic products
