| Abstract: |
| The qualitative description of the depth and layers of
the built environment can no longer meet the needs of accurate
and quantitative analysis in the landscape research and practice
field. By reviewing the progress of the research on depth and
layers of landscape space, a digital method of depth and layers of
landscape space analysis based on point cloud technology, which
is the whole process of "data preparation and parameter setting -
algorithm simulation and result visualization - quantitative analysis
and auxiliary judgment" has been developed to deeply describe the
objective features of depth and layers of landscape space in the built
environment. And the proposed method is performed on a selected
number of spatial samples in Qinglü Park and Hexi Ecological
Park of Nanjing. The result shows that the proposed method
has advantages in analysis efficiency, data accuracy and results'
readability over traditional quantitative methods, and illustrates the
potential to meet different research needs. Besides, this paper also
reveals that the proposed method has benefits for refined research
and high-quality practice of landscape space. |
