摘要
渔业资源的可持续利用是渔业可持续发展的核心问题,对其可持续利用的评价则是目前世界海洋渔业可持续发展研究的前沿及热点问题.本文以可持续利用的有关理论为基础,构建了适用于广东省渔业资源可持续利用的评价指标体系,应用层次灰色综合评判模型分析了1978—2007年间广东省渔业资源的可持续利用状况.结果表明:渔业资源的可持续利用水平在整体上呈下降趋势,1998年降至最低,仅为1978年的37.3%;最近10年间开始出现波动上升,2007年升至1978年的55.1%.综合评价结果与现实情况较为符合,故认为将层次灰色综合评判模型应用于区域渔业资源可持续利用评价是可行的.
Sustainable utilization of fishery resources is the key for the sustainable development of fisheries,and its evaluation is a critical topic in the management of fisheries.Based on the theories of sustainable utilization,an index system suitable for the evaluation of the sustainable utilization of fishery resources in Guangdong Province was established,and a hierarchy and comprehensive grey evaluation model was adopted to evaluate this sustainable utilization in 1978-2007.In the study period,the utilization level of fishery resources in this province had an overall decrease,being the lowest in 1998,only 37.3% of that in 1978;but in the nearest 10 years,this utilization level had an increasing trend,with that in 2007 being 55.1% of 1978.The results of comprehensive evaluation were consistent with the observed facts,indicating that the model was feasible to evaluate the sustainable utilization of regional fishery resources.
