摘要： 新工科背景下,高校环境类专业毕业设计普遍存在选题单一、研究浅表化及学科交叉不足等问题。为解决这一困境,本研究以双创战略为引领,创新性地设计了双创课题与毕业（设计）论文递进式综合实验体系。该实验以磁性碳纳米复合材料的制备及其在磁性固相萃取技术（MSPE）中的应用为核心,结合高效液相色谱法（HPLC）检测环境水体中对羟基苯甲酸酯类污染物（parabens, PBs）,系统训练学生掌握材料合成、形貌表征、MSPE条件优化及HPLC分析等专业技能,实现科研能力训练与创新创业教育的深度融合。该模式依托本科教育早期阶段的科研项目积累,将前期成果直接衔接毕业选题,形成“科研能力培养-资源整合-时间管理”三位一体的培养机制,可有效提升学生实践创新能力,缓解考研、实习与毕业（设计）论文的时间冲突,为地方院校培养符合新工科要求的复合型环境人才提供可复制的实践范式。

Abstract: Against the backdrop of emerging engineering education, higher education institutions commonly face challenges in the graduation design projects of environmental science majors, including a narrow range of topics, limited research depth, and insufficient interdisciplinary integration. To address these issues, this study, guided by the national innovation and entrepreneurship development strategy, has developed an innovative progressive comprehensive experimental system that integrates innovation and entrepreneurship initiatives with graduation design and theses. The experiment centers on the synthesis of magnetic carbon nanocomposites and their application in magnetic solid‐phase extraction (MSPE), coupled with high‐performance liquid chromatography (HPLC) for the detection of parabens (PBs) in environmental water samples. It systematically trains students in essential technical competencies such as material synthesis, morphological characterization, optimization of MSPE conditions, and HPLC analysis, thus achieving a deep integration of scientific research skill development and innovation and entrepreneurship education. By leveraging accumulated outcomes from undergraduate research projects conducted in the early stages of their academic programs, this model seamlessly links prior research achievements with graduation thesis topics, establishing a trinity cultivation framework encompassing “scientific research capacity building, resource integration, and time management”. This approach not only enhances students’ practical and innovative capabilities but also mitigates time conflicts arising from preparation for postgraduate entrance examinations, internships, and thesis completion. Furthermore, it offers a reproducible and scalable practical model for local universities aiming to cultivate interdisciplinary environmental professionals aligned with the demands of emerging engineering education.
