The campus environment of multi-greening is currently one of the important issues of green school project conducted by the Ministry of Education. However, children’s preference on campus greening is rarely studied. This research is based on the theory of landscape preference, and utilizes visual simulation to adjust and obtain different 〝visual percepted Greening ratio〞and 〝plant types〞 in campus for comparison. The analysis of data can provide important reference for future campus planning and development in order to understand the differences on the preferences for the best range of green-mass and plant types in the campus.
