【摘要】 以国家自然科学基金在2001～2020年资助的地理信息系统（geographic information system,GIS）类项目数据为研究对象，统计分析二十年间GIS类项目的资助、项目类型、依托单位、所属学科和研究主题等情况；根据关键词建立可视化网络，分析其研究热点和相关科学问题。结果表明，资助领域主要集中于生态系统、土地利用变化、模型模拟、气候变化和城乡规划，主要研究手段有多尺度、模型模拟、不确定性、耦合机制和空间分析等；对院校的资助力度和对其他单位资助力度差异较大，各地区获资助水平不均衡现象突出；GIS、遥感和计算机技术的交叉融合是未来学科发展的主要方向。更多还原

【Abstract】 This study analyzes Geographic Information System(GIS) project funded by the National Natural Science Foundation of China from 2001 to 2020. It evaluates the funding, project types, supporting institutions, disciplines, and research themes over two decades, and identifies research hotspots and scientific questions through a keyword-based visualization network. Findings reveal that there is a concentration of funding in areas such as ecosystems, land use change, model simulation, climate change, and urban-rural planning, that the main research tools are multi-scale analysis, model simulation, uncertainty assessment, coupling mechanisms, and spatial analysis, that there are significant disparities in funding support between universities and other entities, as well as regional imbalances in funding levels, that the interdisciplinary integration among GIS, remote sensing, and computer technology will be a key direction for future discipline development.更多还原
