| Flexible Planning of Regional Ecological Space forEcological Security—A Case Study of TengzhouCity, Shandong Province |

| Abstract: |
| In the critical period of urbanization transformation and
development, the protection of regional ecological environment
and regional ecological security are important issues. Regional
ecological space planning is an effective approach to realize
ecological security pattern. While general regional ecological
space planning focuses on static situation and "blueprint" planning
requirements, and emphasizes the static ecological security pattern
construction technology, ignoring the dynamic interference
mechanism of ecological risk and ecological security and the
flexible adaption planning strategy to deal with risks. From
this point, aiming to construct ecological security pattern, this
paper starts with mechanism of the ecological risk caused urban
expansion, analyses the interference mechanism between ecological
risk and ecological security, sets up urban expansion simulation
model and ecological pattern security evaluation system, then
puts up flexible planning model of the regional ecological space,
which is "dynamic multi-scenario simulation prediction-ecological
spatial security evaluation-flexible strategies". It is hoped to
provide reference for sustainable development, improvement of
ecological space security and optimization of ecological space
planning methods. |
