文章旨在建立一套科学数据平台传播力的综合评价指标体系，优化平台的传播策略，提升其影响力和服务效能，以期为平台的持续发展提供理论与实践支持。将5W传播模式理论与层次分析法（AHP）相结合，确立传播主体、内容、渠道、受众及效果5个一级评价指标、19个二级指标，并对各指标的权重值进行量化。结果发现，运营专业性、描述型元数据的质量、传播渠道的多样性、用户反馈的及时性与有效性，以及用户行为效果是科学数据平台传播力的关键因素，并从平台的运营、元数据、交互渠道等方面提出建议。
This study aims to establish a comprehensive evaluation index system for the dissemination power of scientific data platforms, optimize the platform's dissemination strategies, enhance its influence and service efficiency, in order to provide theoretical and practical support for the sustainable development of the platform. The 5W communication model theory is combined with the Analytic Hierarchy Process (AHP) to establish five primary evaluation indexes for Dissemination subjects, content, channels, audiences, and effects, as well as 19 secondary indexes. The weight values of each indicator are quantified. The results found that operational professionalism, quality of descriptive metadata, diversity of dissemination channels, timeliness and effectiveness of user feedback, and user behavior effects are key factors in the dissemination power of scientific data platforms. Suggestions are proposed from the aspects of platform operation, metadata, and interaction channels.
