典型海洋开发活动经济产出与资源环境综合效益评估分析

海洋开发活动在产生社会经济效益的同时也造成了海洋资源的损耗,并对海洋环境及其生态服务功能产生影响。根据江苏省海洋资源开发活动特点,筛选出江苏海岸带资源开发中常见的5种典型的开发利用方式,选取了经济效益指标、社会效益指标、资源损耗指标、环境成本指标构成海洋开发活动综合效益评估体系,采用灰色关联法定量分析各项目以及其评价指标对综合效益的贡献程度。其中围海养殖、海上风电、排污倾倒、城镇建设与综合效益的关联度均值分别为0.464,0.459,0.509和0.490;临港工业开发方式与综合效益的关联度均值为0.657,处于较好状态,所以建议优先选择临港工业开发方式,从而得出海洋开发方式的选择依据。

Comprehensive Benefit Evaluation Analysis on the Economic Output and Resource Environment of Typical Marine Development Activities

In the production of social and economic benefits,the marine development activities have also caused the loss of marine resources and even influenced on the marine environment and its ecological service function.Based on the characteristics of marine resources development activities in Jiangsu Province,five typical development and utilization modes commonly encountered in the exploitation of coastal resources in Jiangsu are selected,and the economic benefit index,the social benefit index,the resource loss index and the environmental cost index are selected to constitute the comprehensive benefit evaluation system of marine development activities.The gray correlation method is used for quantitatively analyzing the contributions of each item and its evaluation index to the comprehensive benefit.The mean values of the correlation degree between the reclaimed mariculture,offshore wind power,sewage dumping,urban construction and the comprehensive benefit are 0.464,0.459,0.509 and 0.490,respectively.The correlation mean between the port vicinity industrial development mode and the comprehensive benefit is 0.657,indicating a better state.Therefore,a port vicinity industrial development mode should be suggested first,which gives the selecting basis for the marine development mode.
