威海市海洋渔业资源可持续利用评价研究

摘要

Based on the analysis of the characteristics of marine fishery resources from 2007-2015, the evaluation index system of sustainable utilization of marine fishery resources in Weihai City was constructed using the principle of Analytic Hierarchy Process (AHP). The index system Included the environmental subsystem, the social subsystem and the economic subsystem. The gray comprehensive evaluation model was used to quantitatively evaluate the marine fishery resources of Sustainable use level of Weihai from 2007 to 2015.The results showed that the comprehensive evaluation value of sustainable utilization of marine fishery resources in Weihai was 0.45 in 2007. In 2008, the evaluation value decreased to 0.15 in 2007, 33.2% in 2007, and the evaluation value in 2009 rose to 0.48, 2010, once again dropped to a low level of 0.17, only 35.9% in 2009, 2010-2014 evaluation value has been maintained at a very low level, the level of sustainable utilization of marine fishery resources has been in a low state. 2015 , The evaluation value reaches the maximum value of 0.82, which is 5.54 times of the lowest value. The sustainable utilization level of marine fishery resources is obviously improved.%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。
