基于海域承载力的海洋渔业空间布局合理度评价——以山东半岛蓝区为例

The Rationality Evaluation of Spatial Arrangement of Marine Fishery Based on Marine Carrying Capacity Vision:Exemplify Shandong Blue Area

基于海域承载力视角,从经济效益、社会效益、资源环境效益和功能一致性等角度分别选取因子构建海洋渔业空间布局合理度评价模型,以山东半岛蓝色经济区2006—2011年数据为例进行实证分析。研究结果表明,"蓝区"海洋渔业空间布局合理度在2007年为最低水平0.3011,处于较不合理等级;于2011年为最高水平0.7531,达到较合理等级;其余年份合理度均介于0.4—0.5之间,处于基本合理等级。结合因子分析得出,与功能区划不一致、专门化程度较低、社会效益波动较大、对海域承载力的稳定性存在负面影响是目前"蓝区"海洋渔业空间布局存在的主要问题,并据此提出相应的合理度优化对策。

Based on the view of marine carrying capacity, the article chooses several factors,including economicalbenefits, social benefits, environmental benefits and functional accordance, to establish a rationality evaluation model ofspatial arrangement of marine fishery, which does empirical analysis for Shandong Blue Area with data from 2006 to 2011.The research results show that the rationality of spatial arrangement within ＂Blue Area＂ marine fishery is barelyacceptable between 0.4 and 0.5 every year except for 2007, which is only 0.3011,fairly next to irrational, and 2011obtained the highest value of 0.7531.Together with factor analysis,this paper concludes that deviation from functiondivision,low degree of speciality, huge fluctuation of social benefits as well as existing negative impact on the stability ofmarine carrying capacity are currently the major problems faced by spatial arrangement of＂Blue Area＇marine fishery, onwhich a certain number of suggestions about refining rationality should be proposed accordingly.
