| Abstract: |
| Based on the connotation and development trend of
biophilic urbanism, combined with the occurrence and operation
mechanism of ecological processes in the high-density built
environment, and clarifying the constraints and essential supporting
conditions, a technical framework for defining the scope of highdensity
built environment, assessing and identifying habitat units,
simulating the habitat networks, and comparative assessment by
scenario iteration is created. The downtown of Chengdu, the Park
City demonstration area, is taken as the research object, and the
scope and characteristics of the high-density built environment and
the constraint conditions and ecological process characteristics of
its internal ecological process are analyzed. From the perspective
of human perception, the biological features and supporting
requirements are explored, and then the technical path to evaluate
the habitat network pattern is built. By clarifying the ecological
resistance characteristics and the core habitat spaces, the technology
module of Linkage Mapper based on the electric current theory
is used to identify the habitat networks supporting the biological
characteristics. Moreover, the pattern structure, habitat units,
ecological corridors, ecological pinch points, and ecological
barrier points are evaluated to obtain comparative conclusions by
supplying habitat patches while combining the scenario iteration.
The optimization and promotion strategies such as anchoring the
ecological skeleton, extending the potential ecological context
and creating multi-biological perception spaces are refined. It is
expected to provide guidance and reference for constructing the
Chinese Park City with the characteristics of a living community to
achieve a biophilic city. |
