基于模糊层次法的张网作业性能评价体系构建及实例应用

张网是一种沿海和内陆水域的重要渔具,具有良好的经济效益。由于选择性差和对资源的破坏性,对张网性能的评价尤为重要。运用模糊层次方法,在渔业专家问卷数据的基础上,按照隶属度原则确定张网作业性能评价体系的一级指标及二级指标,以及确定考核指标的权重,并通过了一致性检验对指标权重进行了调整,确保评价体系指标权重的合理性。在以上基础上构建了张网作业性能评价模型,运用实例验证评价体系的科学合理性,为今后的张网作业性能评价提供参考和依据。

Studies and Application on Evaluation Index System for the Stow Net Operation Performance via the Vague APH Method

Stow net is a kind of important fishing gear in coastal and inland water area, with good economic benefit. Since the bad performance in selectivity and resources conservation, evaluation for stow net is significant. For grasping the operation performance of stow net, setting the performance evaluation standard, establishing the evaluation index system, this study used vague APH method, and referred the concept of membership degree in vague APH method, based on the questionnaire data of fishery specialist; the first level and second level index and respective weight distribution of evaluation index system for stow net operation performance were obtained. The weight of index was adjusted through consistency judgment for assuring the rationality of index weight. Evaluation index system for stow net operation performance was established based on the above mentioned studies, and the rationality of evaluation index system was proved by instance application, and the reference basis was provided for stow net operation performance evaluation in the future.
