毕业论文作为本科生培养的重要环节,能综合检验学生对所学知识的掌握和运用能力.本研究采用年滑动平均值法及一元线性回归法,分析了兰州大学草业科学本科专业毕业论文选题领域构成,比较了国内主要高校草业科学专业本科生参与科研创新训练及论文发表情况.分析表明,1) 草业科学专业本科毕业论文选题中草地生态、植物逆境生理和草地保护学呈大幅增加趋势,其比例分别为31.4％、16.7％ 和15.0％,而种质资源与育种领域呈降低趋势,其比例为17.0％;2) 国内开设草业科学专业主要高校均重视本科生科研创新训练及毕业论文质量,但本科生发表论文整体较少.因此,建议通过引导学生积极参与科研创新训练,加强本科专业核心或骨干课程论文撰写,并从论文选题、完成时间、老师指导及论文评审和考核等方面提升草业科学本科毕业论文质量.%The undergraduate thesis is an important part of undergraduate cultivation, which can systematically examine students' ability of using the knowledge acquired in undergraduate period. In this study, we investigated the change pattern of the research fields of undergraduate thesis for Pratacultural Science majors at Lanzhou University by using the moving average and the linear regression equation methods, and also compared the participation proportion of Pratacultural Science undergraduates in scientific research items and number of publishing papers in main Chinese universities. The results showed that: 1) In the main topics of undergraduate thesis were a largely increasing, such as grassland ecology, stress physiology, and grassland protection, accounting for 31.4％, 16.7％ and 15.0％, espectively, but forage germplasm resources and breeding was a quickly decreasing, accouniting for 17.0％. 2) Universities offering Pratacultural Science in China have attached great importance to undergraduate scientific training and undergraduate thesis quality, but a few number of papers were published by undergraduate students. In order to improve the quality of undergraduate thesis, we suggest that the students should positively participate in scientific innovation training, and higher education institutions should strengthen the papers writing in core courses for Prataculatural Science majors, and the teachers and students should pay more attentions to the topics selection, experiment and writing time of thesis, and the teacher's advice effect and the thesis evaluation and examination.
