| Abstract: |
| With the scenic forests of Purple Mountain National
Forest Park as the object of study, the evaluation on visual quality
was conducted in this research to analyze the factors and core
components which affected the visual quality. The impact factors
were translated into principal components through principal
component analysis (PCA), and the visual characteristics when
people appreciated scenic forests were analyzed integrated with
eye movement diagrams and principal components. Five principal
components that influenced visual quality were close-to-nature
degree of scenic forests, regional cultural characteristics, abundance
of colors, easily-recognized features of arbors and spaciousness in
forests respectively. Among the principal components, influences
that close-to-nature degree of scenic forests, regional cultural
characteristics and abundance of colors had on visual quality were
the most significant. The study can be helpful to the management of
scenic forests and the plant landscape construction. |
