【摘要】：全面收集整理了2007-2015年威海市渔业资源、经济和社会统计数据,在分析海洋渔业资源特点基础上,利用层次分析法原理构建了威海市海洋渔业资源可持续利用评价指标体系,该指标体系包括资源环境子系统、社会子系统和经济子系统3个层次的24个指标,采用层次分析法确定各指标的权重,应用层次灰色综合评价模型首次定量评估了2007-2015年威海市海洋渔业资源可持续利用水平。结果表明:2007年,威海市海洋渔业资源可持续利用综合评价值为0.45,2008年,评价值降至近9年的最低值0.15,仅为2007年的33.2%,2009年评价值回升到0.48,2010年,再次下降到较低的水平0.17,仅为2009年的35.9%,2010-2014年评价值一直维持在极低的水平,海洋渔业资源可持续利用水平一直处于较低的状态,2015年,评价值达到最大值0.82,是最低值的5.54倍,海洋渔业资源可持续利用水平明显提高。
[Abstract]:The fishery resources, economic and social statistical data of Weihai City from 2007 to 2015 are collected and sorted out in an all-round way. on the basis of analyzing the characteristics of marine fishery resources, the evaluation index system of sustainable utilization of marine fishery resources in Weihai City is constructed by using the principle of analytic hierarchy process (AHP). The index system includes 24 indexes at three levels: resource and environment subsystem, social subsystem and economic subsystem, and the weight of each index is determined by analytic hierarchy process (AHP). The level of sustainable utilization of marine fishery resources in Weihai City from 2007 to 2015 was quantitatively evaluated by using hierarchical grey comprehensive evaluation model for the first time. The results show that in 2007, the comprehensive evaluation value of sustainable utilization of marine fishery resources in Weihai City is 0.45. in 2008, the evaluation value decreased to the lowest value of 0.15 in nearly 9 years, which was only 33.2% in 2007. The evaluation value rebounded to 0.48 in 2009. In 2010, it dropped to a lower level of 0.17, only 35.9% in 2009, and the evaluation value remained at a very low level from 2010 to 2014. the comprehensive evaluation value of marine fishery resources in Weihai City was 0.45. in 2008, the evaluation value decreased to the lowest value in nearly 9 years, which was only 33.2% in 2007. The level of sustainable utilization of marine fishery resources has been in a low state. In 2015, the evaluation value reached the maximum value of 0.82, 5.54 times of the lowest value, and the level of sustainable utilization of marine fishery resources was obviously improved.
