摘要： 我国正全面推进“双碳”战略与海洋强国建设，对海洋化学专业人才知识体系、科研能力与综合素养等方面提出了更高要求。海水碳酸盐体系是海洋化学教学的核心内容，针对传统实验教学中知识逻辑割裂与参数关联薄弱的问题，本文以海水碳酸盐体系研究为载体，将pH、总溶解无机碳(DIC)和总碱度(TA)测定重构为模块化综合实验。学生通过系统观测计算，探究碳酸盐各组分分布特征与环境效应。实践表明，该设计强化了多参数耦合分析与建模思维，可为同类化学实验改革提供参考。

Abstract: As China advances its dual-carbon strategy and the development of a maritime power, greater demands are being placed on the knowledge base, research capabilities, and overall competence of professionals in marine chemistry. The seawater carbonate system constitutes a core component of marine chemistry education. To address the issues of fragmented knowledge and weak parameter correlations in traditional experimental teaching, this paper presents a modular comprehensive experiment built around the seawater carbonate system, in which measurements of pH, dissolved inorganic carbon (DIC), and total alkalinity (TA) are restructured into an integrated framework. Through systematic observation and calculation, students explore the distribution characteristics of carbonate species and their environmental implications. Practical implementation demonstrates that this design enhances students’ abilities in multiparameter coupling analysis and modeling thinking, offering a valuable reference for reforming analogous chemistry laboratory courses.
