Marine ranching plays an integral role in providing fishery resources. Given the critical importance of protecting the marine ecological system, the ecological security evaluation of marine ranching is significant. However, the existing research rarely involves marine ranching ecological security (MRES) evaluation and does not provide a complete evaluation index system. The purpose of the present study was to estimate MRES through several steps and evaluate it scientifically by fully considering the relationship between the factors. First, the evaluation index system was structured using the Driver-Pressure-State-Impact-Response (DPSIR) framework by following certain principles. Second, the study applied the Decision Making Trial and Evaluation Laboratory (DEMATEL) method and fuzzy comprehensive evaluation (FCE) method to assess MRES. Third, a case study of a marine ranching in the Shandong Province was discussed to demonstrate the applicability of the proposed method. This also illustrated the steps of the evaluation. In this case study, the result of the MRES evaluation was graded as excellent. The results demonstrate that using these methods to evaluate MRES can account for the complex relationships between the factors and the cognitive ability of the experts and thus integrate the experts’ information comprehensively, which adds to the credibility of the evaluation results.

基于DEMATEL-模糊综合评价的海洋牧场生态安全评价

海洋牧场在提供渔业资源方面起着不可或缺的作用。鉴于保护海洋生态系统至关重要，海洋牧场的生态安全评价意义重大。但是，现有研究很少涉及海洋牧场生态安全评价，也没有提供完整的评价指标体系。本研究的目的是通过几个步骤来估计MRES，并通过充分考虑因素之间的关系进行科学评估。首先，使用驱动程序-压力-状态-冲击-响应（DPSIR）框架，按照某些原则构建评估指标体系。其次，该研究采用了决策试验和评估实验室（DEMATEL）方法和模糊综合评估（FCE）方法来评估MRES。第三，以山东某海洋牧场为例进行了讨论，以证明该方法的适用性。这也说明了评估的步骤。在本案例研究中，MRES评估的结果被评为优秀。结果表明，使用这些方法对MRES进行评估可以解决因素与专家认知能力之间的复杂关系，从而全面整合专家的信息，从而提高了评估结果的可信度。
