基于层次分析法的舟山市海洋牧场选址评价

Site selection evaluation of marine ranching in Zhoushan area based on AHP method

海洋牧场作为现代渔业的一种发展模式,其选址技术在整个海洋牧场建设体系中起着十分关键的作用。以舟山市海洋牧场建设规划为例,根据其不同类型的海洋牧场建设目标,在分析影响海洋牧场选址因素的基础上,采用层次分析法构建海洋牧场选址评价的层次结构模型,采用专家调查法构建判断矩阵,利用Yaahp 5.3R1软件一一计算判断矩阵,并进行一致性检验,依次按照层次单排序和总排序的顺序进行。计算得到各选址方案的权重值。结果表明,舟山市规划的4个海洋牧场选址的优劣排序依次为:马鞍列岛海洋牧场(0.289 5)、东极岛海洋牧场(0.276 6)、洋鞍—猫头洋海洋牧场(0.221 9)和岱山东部列岛海洋牧场(0.212 0)。舟山市可以优先安排资金和项目开展马鞍列岛海洋牧场和东极海洋牧场的建设工作。

In order to construct marine ranching in Zhoushan effectively,after analyzing the factors affecting the site selection of marine ranching,using AHP method to build up the evaluation model,we set up judgment matrix by delphi method,using Yaahp 5.3R1 software to evaluate the judgment matrix,and checked the consistency of judgment matrix,at last,obtained the weight value of the different projects.The result showed that the preferential order of the four sites selection is Ma＇an archipelago marine ranching（0.289 5）,Dongji island marine ranching（0.276 6）,Yang＇an-Maotou marine ranching（0.221 9）,and East Daishan island marine ranching（0.212 0）.Zhoushan City could give priority to funding and project to construct Ma＇an archipelago marine ranching and Dongji island marine ranching.
