Abstract:
The plots were arranged along the main ornamental roads of Jinpo and Pudi scenic regions and the seeds of Orychophragmus violaceus were sow in these three allocation ways,A（the major dominant azaleas species with Orychophragmus violaceus),B（single the major dominant azaleas species）and C（single Orychophragmus violaceus）to carry out the contrast experiment.The data of the flowering period，the average total bloom amount and the planting density of the major dominant azaleas species and Qrychophragmus violaceus；the space hierarchy change in the plots of two scenic regions in three allocation ways before and after planning the Qrychophragmus violaceus in standard plots of two scenic regions in three allocation ways，the effect on flower appreciation of two scenic regions by planning Qrychophragmus violaceus in different allocation ways had been studied.The results showed that there were positive influences on prolonging the appreciation time，increasing the space hierarchy and enriching the effect on landscape appreciation by planting Orychophragmus violaceus,which provided a guarantee for good continuity of this good landscape.Meanwhile，from the view of landscape ornamental effect，according to the Golden Ratio theory and landscape coordination，the best average planting densities of Orychophragmus violaceus in different plots were recommended the optimal average planting densities of Orychophragmus violaceus in the plots of Pudi and Jinpo scenic regions with A allocation was 6.9 plant/m2 and 9.1 plant/m2，respectively;the optimal average planting densities of Orychophragmus violaceus in the plots of Pudi and Jinpo scenic regions with C allocation was 17.63 plant/m2 and 17.12 plant/m2，respectively.
