山东半岛蓝色经济区海域承载力评价

Evaluation of Carrying Capacity of Marine Space in the Shandong Peninsula Blue Economic Zone

为研究山东半岛蓝色经济区海城承载力状况,构建了山东半岛蓝色经济区海域承载力评价指标体系,包括3类具体评价指标:压力类指标、状态类指标和区际交流指标。根据山东半岛蓝色经济区2007—2014年统计数据计算出各项评价指标。采用均方差分析法确定评价指标权重,结合归一化处理后的指标数据,计算海域承载力评价指数值。对承载力评价指数值分析,结果表明:山东半岛蓝色经济区压力指数总体呈下降趋势,承载力指数总体呈上升趋势,承压比总体呈上升趋势,海域整体承载力状况呈向好趋势。根据评价指数分析结果,对提升山东半岛蓝色经济区海域承载力提出了几点对策:控制人口增长,促进海洋科技进步;优化海洋产业结构,促进海洋经济转型;加强海洋环境保护,加大环保投资力度。

An evaluation index system is established for the carrying capacity of marine space in the Shandong Peninsula Blue Economic Zone,which consists of three types of specific evaluation indexes,i.e.the pressure index,the state index and the inter-regional communication index.All these indexes are calculated based on the statistic data obtained in the SPBEZ from 2007 to 2014.The weights of the evaluation indexes are fixed by Mean Square Difference Analysis and the exponential quantity of the sea area carrying capacity are calculated by combining the index values obtained after normalization processing.The analysis of the exponential quantity indicates that the pressure index of the SPBEZ tends generally to decline and the carrying capacity index shows an uprising tendency in general.The ratio of the carrying capacity to the pressure is generally uprising and the overall carrying capacity of the sea area tends to become better.According to the analysis of the evaluation indexes,several countermeasures are put forward for enhancing the carrying capacity of the sea area in the SPBEZ,which include to control the speed of population growth,to promote the marine science and technology progress,to optimize the marine industrial structure,to promote marine economy transformation,to enforce the protection of marine environment and to increase investment in environmental protection efforts.
