基于综合赋权法的海洋资源环境承载能力综合评价研究——以长江经济带邻近海域为例

Research on evaluation of carrying capacity of marine resources and environment based on comprehensive weighting methods——a case study in coastal ocean near the Yangtze River Economic Belt

海洋资源环境承载能力评价是促进协调沿海地区社会经济、资源与环境关系平衡的重要方法,是衡量海洋可持续发展的技术手段,构建一种量化的海洋资源环境承载能力综合评价方法十分必要。本研究基于主客观综合赋权法,建立了海洋资源环境承载能力综合评价方法,以长江经济带邻近海域43个县级评价单元为例对海洋资源环境承载能力综合评价方法进行了实证分析。研究结果表明,综合赋权法结合层次分析法和熵值法的优点合理地确定了指标权重,获得了各评价单元海洋资源环境承载能力综合评价得分,连云港和盐城海洋资源环境承载能力情况较好。

The evaluation of carrying capacity of marine resources and environment is an important way to balance the relationship of economy,resources and environment near coastal zone. The evaluation of carrying capacity of marine resources and environment also is a technical method of marine sustainable development. It＇s necessary to construct a quantitative evaluation method of carrying capacity of marine resources and environment. Based on comprehensive weighting methods,an evaluation method of carrying capacity of marine resources and environment is built. A case study in coastal ocean near Yangtze River Economic Belt is conducted with the evaluation of carrying capacity for marine resources and environment. There are 43 counties as the units of the evaluation. The results show that the comprehensive weighting methods is better than the analytic hierarchy process and the entropy method to calculate the weight.Composite scores of the evaluation of carrying capacity are got for every unit of the evaluation. The carrying capacity ofmarine resources and environment of Lianyungang and Yancheng is good.
