基于生态足迹的江苏省渔业资源可持续利用评价

Assessment on Sustainable Utilization of Fisheries Resources Based on Ecological Footprint in Jiangsu Province

渔业资源可持续利用是实现渔业可持续发展的基础,如何评价其可持续利用是重要的科学问题。本文基于生态足迹理论构建了渔业可持续指数的评价框架,并利用该评价指数对江苏省1949～2007年的渔业资源利用状况进行了定量评价。结果显示:1949～1978年的近30年间,江苏省渔业资源基本处于可持续利用状态,但改革开放以后,尤其是1980、1990年代总体处在较强的不可持续利用状态,过度捕捞是导致渔业资源不可持续利用的重要原因;2000年以后不可持续性程度有所减缓,说明伏季休渔、增殖放流等生态保护措施已初见成效。最后就如何提高渔业资源可持续性水平,降低经济社会发展对渔业资源的负面影响提出了一些建议。

Sustainable utilization of fisheries resources is the groundwork to realize sustainable development for fisheries,and how to assess its sustainability is also the important science problem.A framework of assessment on sustainability of resources in fishery is designed based on ecological footprint theory,by which the status of fishery resources utilization is quantificationally evaluated from 1949 to 2007 in Jiangsu Province.The results show that during the period of nearly 30 years from 1949 to 1978,fisher...
