基于生态足迹修正模型的江苏省海洋经济可持续发展分析

基于生态足迹的理论和方法,提出海洋生态足迹的概念,并根据江苏省海洋环境的特殊性,构建了渔业用海、交通运输用海、工程建筑用海、能源用海、滩涂5个海洋生态足迹子模型,采用改进熵值法确定5类用海的均衡因子,分析了2000-2008年江苏省海洋生态足迹和生态承载力.结果表明:2000-2008年间,江苏省人均海洋生态足迹增幅近7倍,从36.90 hm2上升到252.94 hm2;人均生态承载力从105.01 hm2增至185.49 hm2,呈平稳增长态势;2000年,江苏省海洋环境处于生态盈余状态,海洋经济呈弱可持续发展状态,2004年,海洋生态环境急剧恶化,生态赤字高达109660.5 hm2,海洋经济可持续能力下降.渔业用海的高生态足迹是造成江苏省海洋生态赤字的主要原因,滩涂是维持江苏省海洋经济可持续发展的重要后备资源.

Analysis on sustainable development of marine economy in Jiangsu Province based on marine ecological footprint correction model

Based on the theories and methods of ecological footprint,the concept of marine ecological footprint was proposed.According to the characteristics of marine environment in Jiangsu Province,five sub-models of marine ecological footprints,including fishery,transporation,marine engineering construction,marine energy,and tidal flat,were constructed.The equilibrium factors of the five marine types were determined by using improved entropy method,and the marine footprints and capacities in Jiangsu Province from 2...
