Abstract:In view of the wide range of outdoor landscaping evaluation indicators and the complex relationships, it is difficult to evaluate the succulents effectively and comprehensively. By using the Scenic Beauty Evaluation method, three evaluation indexes of ecology, aesthetics and maintenance were selected to evaluate three different types of succulent landscapes. And through the partial correlation analysis, the evaluation factor with the smallest correlation coefficient is eliminated, and the community level, coordination, symbiosis, diversity, unity, balance, stability, color matching, rich colors, plant growth, and surrounding environment, which contribute a lot to the scenic beauty value, are retained. Finally, the multi-linear backward regression method was used to establish the evaluation model of succulent landscape scenic beauty by SPSS 18.0, namely Y =0.201 X1+0.177 X2+0.072 X3+0.069 X4+0.210 X5+0.120 X6+0.106 X7+0.117 X8. Among them, Y is the standard value of succulent landscape scenic beauty, X1 means community level, X2 means coordinated symbiosis, X3 means diversity and unity, X4 means balance and stability, X5 means color matching, X6 means rich colors, X7 means plant growth, and X8 means surrounding environment. The results of this study can provide a more scientific approach to the evaluation, design, and construction of outdoor landscapes for succulents.
