摘　　要：本文采用用户分类调查和模糊评价方法,对互联网地图搜索引擎案例的视觉质量现状进行综合评估和横向比较,并对评语细化差异进行分类分用户的多变量可视化分析。总体评价结果为"良",国外比国内略好。其中,各指标权重表明,颜色配置、界面构图和道路表达对互联网地图的视觉效果起首要的决定作用。最后,基于用户为中心和跨学科协同的理念,提出平衡制图专业研究倾向、多领域协作、结合传统与规范、重视用户反馈和公众参与等优化建议。研究表明,模糊分析和多变量可视化的结合,能够实现定性与定量分析、主观与客观评价的协调。Using Fuzzy assessment methods,this paper presented a comprehensive evaluation on the visual quality of 24 domestic and 10 foreign web map search engines,followed by a comparative analysis.The studied data were collected from four user categories through web-based questionnaires firstly.The result showed that the most web map cases received the rank of＂Good＂,among which the foreign cases were a little better than the domestic ones.Then multivariate visualizations were applied to examine the fine discrepancies of the user comments,and some latent issues among individual cases were revealed.Besides,the weights of evaluation factors indicated that color design,interface layout and road system representations were foremost determinants for the visual impression of web maps.Finally,based on a user-centered and interdisciplinary perspective,the paper proposed optimization principles by considering the balance of research preferences,collaboration of related domains,integration of conventions and innovation,user feedback and public participation.As a conclusion,the combined methodology of Fuzzy assessment and multivariate visualization demonstrated harmony between qualitative and quantitative analyses,subjectivity and objectivity of the quality evaluation.
