Through anonymous questionnaires, face to face interviews and evaluations from employment agencies, centered around curriculum setting, course content, teaching methods, practical teaching and harvests from the courses, investigation and analysis of teaching effect of plant courses have been carried out aiming at graduates of landscape architecture in Southwest Jiaotong University from 2010 to 2015. There are many defects in plant courses in the background of architecture, such as lack of class hours, basic courses, and curriculum depth, as well as separation between practice and design. Upgrading subject status, reforming curriculum system, improving teacher structure, and building practical platforms are raised and discussed, to provide effective reference for the training of landscape architecture talents with scientific and aesthetic thinking.
