Abstract: Combining with the rules and characteristics of the talents training in Application-oriented Landscape Architecture.the teaching philosophy of "learning-by-doing" is run through the whole process of talents training,and the ornamental botanical garden as a practical teaching platform in campus is constructed adopting to local conditions.Students could recognize plants,master breeding and reproduction,and participate in planning and design,and maintenance management in botanical gardens.They could carry out the theoretical study and practical education as well as scientific research activities in botanical gardens at any time and anywhere.Based on students' eyes,hands and brains,the teaching mode of "learning-by-doing" is constructed.Thus,this teaching mode lays the foundation for realizing the "zero adaptation period" after students' employment through the "four-year-continuous-line" of practical teaching system and other safeguard mechanisms.
