Abstract: According to the principles of sustainable development, the index system for comprehensive evaluation of the benefits of efficient ecology fishery is established and applied to assess the time sequence (1992–2011) and spatial variation (five districts) of Dongying City. The index system is constructed by 3 criterion layers and 21 factors. The score of each factor was calculated, by analytic hierarchy process (AHP) and expert scoring method to determine the weight. Results show that the comprehensive benefits present a rising trend on the whole, and can be divided into 3 stages: 1992–1998, fluctuating at a low level; 1998–2006, rapid promotion; 2006 till now, stable and coordinated development. The total benefit has the same variation trend with economic benefit, while has a negative correlation with ecological benefit in some years. For the regional comparison, Kenli leads all other districts in every benefit. Hekou takes the second place, and Dongying and Guangrao districts perform poor. The research is an important support for further planning of fishery policy in Dongying City.

摘要: 根据渔业系统可持续发展的原理, 借鉴相关评价方法, 构建高效生态渔业综合效益指标体系, 对位于黄河三角洲主体部分的东营市进行高效生态渔业的综合效益评估, 包括时间序列(1992—2011 年)和内部空间分异(三县两区)的定量综合评价研究。指标体系分为3 个层次, 共21 个指标。采用线性加权法进行多指标综合评价合成, 其中, 数据标准化采用Z-score 法, 权重确定采用层次分析法和专家打分法。结果表明, 自 1992 年以来, 东营市渔业综合效益整体呈现上升趋势, 并可划分为3 个阶段: 1992—1998 年低水平波动, 1998—2006 年效益快速提升, 2006 年至今稳定协调发展。总效益与经济效益的变化趋势基本一致, 与生态效益在部分年份呈现负相关。从区域比较来看, 垦利县各项效益均领先其他区县, 河口区次之, 东营区和广饶县渔业发展较差。该综合评估结果可为东营市制定渔业发展政策提供科学支持。
