摘　　要：为探究影响宅间植物景观质量的主要因素,文章运用美景度评价法对长沙市的117个植物景观单元进行评价,分析美景度值与景观要素之间的关系。单因素方差分析得出,对景观质量影响较大的项目有灰色比、林下灌草覆盖率、植物冠形、视野通透度、树干可见性、植物层次丰富度、枯落物。各项目随着美景度值的增大,灰色比变化趋势不明显;林下灌草覆盖率呈上升趋势;植物冠形向球形或半球形靠拢;视野通透度呈下降趋势;树干可见性变化趋势不明显;植物层次向丰富方向靠拢;枯落物呈减少趋势。以筛选出的7个项目建立线性回归模型,结果显示枯落物对景观美景度模型的贡献最大,其次是植物层次丰富度、林下灌草覆盖率、灰色比、植物冠形、视野通透度、树干可见性。In order to explore the main factors affecting the quality of plant landscape between houses,the paper evaluated 117 plant landscape units in Changsha City using the method of Scenic Beauty Estimation,and analyzed the relationship between SBE value and landscape element. One Way ANOVA showed that Gray Ratio,Mixed Type,Coverage of Undergrowth,Allocation Mode,Average Plant Height,Plant Crown Shape,Visual Field Penetration,Trunk Visibility,Plant Layer Richness and Litters had significant impacts on landscape quality. With the increase of SBE value,Grey Ratio showed no clear change trend;Coverage of Undergrowth was increasing;Plant Crown Shape was approaching to spherical or hemispherical square;Visual Field Penetration was decreasing;Trunk Visibility had no obvious change;Plant Layer Richness was higher;Litters presented a decreasing trend. A linear regression model was established using the 7 elements. The results showed that Litters contributed the most to esthetic evaluation model,followed by Plant Layer Richness,Coverage of Undergrowth,Grey Ratio,Plant Crown Shape,Visual Field Penetration and Trunk Visibility.
