分析30年学术主题地图设计，发现中英文地图趋同而非分化。
Evolving Thematic Map Design in Academic Cartography: A Thirty-Year Study Based on Multilingual Journals
- 基于4.5万篇论文提取2.4万张地图，量化分析元素、色彩与布局。
- 中英文地图均用低饱和、高亮度的中性色，布局以中心为主且占比高。
- 尽管细节有差异，但整体演变趋势一致，体现学术规范趋同。
主题地图在学术传播中居核心地位，但其大规模设计演化罕有实证研究。本研究基于1990至2020年十六种中英文权威期刊的45,732篇论文，利用计算机视觉与大模型文档解析技术提取23,928幅地图，构建结构化数据集。从地图元素、色彩设计和版式结构三个维度量化分析设计特征。结果表明，中英文学术地图在结构上高度相似：普遍采用低饱和度、高亮度、色调单一的中性配色，主图占版面比例高，布局多为居中型。差异方面，英文地图略具更丰富的色调与更紧凑的版式，而中文地图历史上更依赖中性色调与整合式布局。时间演化分析显示，两组地图均呈现元素丰富度、图例使用率及色调多样性上升的趋势，版式结构则保持稳定。总体而言，学术地图设计的演进更多体现制度性趋同，而非文化分化。
原文摘要 · Abstract (English)
Thematic maps play a central role in academic communication, yet their large-scale design evolution has rarely been examined empirically. This study presents a longitudinal and multilingual analysis of thematic map design practices in academic cartography from 1990 to 2020. We compile a corpus of 45,732 research articles from sixteen authoritative Chinese- and English-language journals and extract 23,928 maps using computer vision and large-model-based document parsing to build a structured dataset. Map design characteristics are quantified across three dimensions: map elements, color design, and layout structure. Results show that Chinese- and Englishlanguage academic maps share highly similar structural conventions, typically employing restrained color palettes with neutral dominant hues, low saturation, high brightness, and limited hue diversity, as well as centered layouts with high main-map occupation ratios. Differences exist in that English-language maps show slightly greater hue richness and compactness, whereas Chinese-language maps historically rely more on neutral hues and integrated layouts. Temporal analysis reveals parallel evolutionary trends in both groups, including increasing element richness, legend usage, and hue diversity, alongside stable layout structures. Overall, the findings suggest that academic map design evolution is characterized more by institutional convergence than cultural divergence.
