摘　　要：[目的]探讨造型树配置造景的观赏效果。[方法]选取游憩绿地中定植的5种造型树和2种非造型树,根据观赏的最佳视域规律,分别在树高1~3倍的视距下运用美景度评价法(scenic beauty estimation,SBE)进行观赏喜好度评价,分析不同视距下的喜好度差异,并进行观赏因子回归分析,以探明造型树的观赏效果及影响因子。[结果]评判者较喜欢1~2倍视距的造型树,在1倍视距时的造型树更受评判者喜欢,且1倍视距的喜好度要显著高于3倍视距(P<0.05);而非造型树不具有类似表现。观赏视距、枝片数量和前景配置是影响喜好度的主要观赏因子,其中,观赏视距存在极显著影响(P<0.01)。[结论]该研究可为造型树观赏位置的设计及造型要素的把握提供参考。[Objective]In order to explore the ornamental effect of bonsai style trees configuration.[Method]Five kinds of bonsai style trees and two kinds of spontaneous trees were selected where in recreational urban greenbelts,according to the best viewing range law,select 1 to 3 times the height of each tree as the viewing sight distance,the scenic beauty estimation(SBE)is used to evaluate the ornamental preference of these trees,analyze the preference differences of different viewing sight distances,and regression analysis and calculation of ornamental factors,the purpose is to explore the ornamental effect and influencing factors of bonsai style trees.[Result]The results show that judges prefer bonsai style trees with 1-2 times viewing distance,bonsai style trees at 1x viewing sight distance is more liked by judges,and the preference of 1x viewing sight distance is significantly higher than that of 3x viewing sight distance(P<0.05),but these spontaneous trees do not behave similarly.The main viewing factors that affect the preference are viewing sight distance,the number of coiled pruning branches,and the scenery in front of these trees,the viewing sight distance has a very significant impact(P<0.01).[Conclusion]This study can provide reference for the design of ornamental position and the grasp of modeling elements of bonsai style trees.
