Abstract: |
Ecological space planning has transitioned from the
"patch" of the traditional urban and rural planning system to
an important leading system in new Chinese territorial space
planning system recently. Using the multivariate analysis could
guarantee the scientific planning and management based on the
rational understanding of characteristics of ecological spaces.
Taking Xiangyang City as an example, multiple technologies were
applied according to the framework of "background evaluation -
pattern optimization - hierarchical control management", such
as ecological sensitivity analysis, ecosystem service evaluation,
least resistance model, corridor simulation based on circuit theory,
etc. The results showed ecological space occupied 56.33% of
Xiangyang City. 35 ecological sources and 73 optimal ecological
corridors were identified. The ecological security pattern of
Xiangyang City showed as "one main stream and seven tributaries,
western barrier and northern network, three green wedges, four
divisions, and multiple nodes". The management control strategies,
the positive and negative list of use control, and the ecological
restoration strategies - protecting green, increasing green, and
replenishing green, were proposed. The research is expected to have
a demonstration and leading role in the practice of ecological space
planning in the new era of the territorial space planning system |
