| Abstract: |
| As a linear and extensive corridor, high-speed rail (HSR) lines
inevitably impact the ecological pattern along their axes. The integration of
HSR construction with environmental restoration along the routes has attracted
widespread social attention. HSR green corridors serve as vital landscape
carriers across China's territorial space, helping to connect the spatial pattern
of HSR with ecological environmental protection. Currently, a significant amount
of research focuses on evaluating the impact of railway construction on the
ecological environment, particularly through the acquisition and analysis of
landscape pattern indices based on land use and land cover maps. However,
there is a lack of research on the landscape planning of HSR green corridors
themselves, as well as an interaction between ecological environmental
impact assessments and the optimization of their landscape spatial structures,
resulting in an incomplete understanding of HSR green corridors. The proposal
and application of an HSR green corridor landscape planning framework
from the perspective of landscape pattern optimization can provide a more
systematic interpretation of China's HSR green corridors, promoting ecological
environmental restoration, enhancement of scenic perception, and synergy of
rural resources along the HSR lines, thereby contributing to the improvement
of the landscape system construction of China's HSR corridors. In terms of
research structure, this study takes landscape components, core landscape
patches, and landscape ecological networks as research premises rather than
conclusions, aiming to establish an effective connection between research
findings and planning practice. It integrates two non-ecological factors—visual
perception along the route and synergistic utilization of rural resources—with
ecological infrastructure optimization to ensure the sustainability of landscape
planning implementation. In terms of research scope, this study defines the
range of landscape planning for the green corridor along the Anji section of the
Shangqiu-Hefei-Hangzhou high-speed railway, which includes the area within
1.5 kilometers on both sides of the railway embankment. This region is not only
significantly influenced by the project in terms of landscape pattern but also a
key area of focus for various planning stakeholders. In terms of research content,
this study constructs a landscape planning framework for high-speed railway
green corridors from three aspects: landscape dynamic changes, potential
landscape issues, and landscape structure improvement. Taking the empirical
study of the Anji section of the Shangqiu-Hefei-Hangzhou high-speed railway as
an example, it proposes an overall planning approach of "prioritizing ecological
foundation restoration and enhancing through linear landscape planning", which
is further expanded into an optimization strategy that integrates "ecological
restoration", "landscape perception", and "industrial coordination". In terms
of research methods, this study relies on the ENVI and ArcMap platforms and
employs quantitative methods such as land use analysis, morphological spatial
pattern analysis, ecological connectivity analysis, and least-cost path analysis,
based on land use classification of different landscape types, to form a technical
pathway for landscape planning of high-speed railway green corridors. |
