吉林省两城市常见绿化植物单体色彩美景度评价

以吉林省长春市、吉林市各类绿地为研究样地,选择70种常用绿化树种为研究对象,采用SBE法、相关分析、方差分析、逐步回归等方法,确定影响园林植物单体色彩美景度的主要因子,建立美景度预测模型.结果表明:树木姿态(F=2.089,P=0.018)、彩叶光泽(F=2.828,P=0.001)是影响园林植物色彩美景度的主导指标;美景度预测模型SBE=-100.706+17.888x1+24.292x9(x1为彩叶光泽,x9为树木姿态);美景度随彩叶光泽、树木姿态等指标分值的提高而显著提高.

Scenic Beauty Estimation on the Common Green Plants Monomers of Two Cities in Jilin

A total of 70 common greening tree species were selected from various green spaces in Changchun and Jilin Cities of Jilin Province.Method s including scenic beauty estimation (SBE),correlation analysis,variance analysis and stepwise regression were used to identify the major factors influencing the colorific beauty of landscaping plant monomers,and to create SBE model.The results showed that the tree posture (F=2.089,P=0.018) and color leaf luster (F=2.828,P=0.001) were the dominant indices influencing the colorific beauty of landscaping plants.The SBE model was established as follows:SBE=-100.706+17.888 x1 + 24.292 x 9 (x 1:color leaf luster,x 9:tree posture).The scenic beauty was enhanced significantly with elevating scores of indices such as color leaf luster and tree posture.
