[目的/意义]论文回答的研究问题是：在新文科建设背景下，图书馆信息学与数据科学、数字人文与健康信息学等新文科交叉领域的关系发展的未来前景是什么？[方法/过程]论文从现有研究文献中图书馆信息学与数字人文、数据科学、健康信息学三个新文科交叉领域的关系类型出发，设计了民族志未来访谈，邀请三十四位国内图书馆信息学和情报学等学科的学者提炼这四个学科（领域）的核心竞争力，判断其相互间价值，并预测2030年最乐观、最悲观和最有可能的发展前景。[结果/结论]图书馆信息学与数字人文、与数据科学、与健康信息学在2030年更有可能出现的前景是并列有交集的关系，健康信息学相对更可能成为图书馆信息学的下位类，数据科学与图书馆信息学的关系相对更独立。

[Purpose/significance] The paper aims to answer the research question: in the context of national new liberal arts strategy, what are the 2030 prospects for the development of the relationships between library and information science (LIS), digital humanities, data science, and health informatics? [Method/process] Starting from the literature on the relationship between LIS, digital humanities, data science, and health informatics, the paper employs the ethnographic future research (EFR) and invites 34 domestic scholars in LIS and related fields to refine the core competitiveness of these four fields, judge their mutual value, and predict the most optimistic, pessimistic, and most likely development prospects in 2030. [Result/conclusion] LIS, digital humanities, data science, and health informatics are more likely to have overlapping relationships in 2030. Health informatics is relatively more likely to become the lower category of LIS. The relationship of data science and LIS is relatively more independent.
