Biodiversity Conservation Planning Based onHabitat Network Optimization |

Abstract: |
Urban green space is the key to carrying biodiversity. The
construction of habitat network based on urban green space helps
to integrate fragmented green patches, promote species exchange
and migration, and provide a basis for biodiversity protection.
There are some problems in the construction process of the existing
habitat network, such as dependence on a single model, neglect of
the actual species in the region, lack of unity in the working path
of network construction, and difficulty in connecting the output
results with the upper planning and practical application in the
planning level. This research in the working content and biodiversity
conservation planning target, based on habitat quality analysis,
geographic detector, minimum cumulative resistance model such
as model method, identify regional source of habitats and corridor,
and considering the range indicator species added important habitat
nodes, build habitat for biodiversity conservation network. The network
construction method of "source identification - corridor simulation - node
extraction - network construction" was systematically optimized.
Docking studies to national spatial planning of green space system
under special planning as the goal, the habitat network builds results
through comparing red and green space classification matching, and
protection measures are proposed from the angle of space control,
to realize the effective connection with the green space system
planning, and build a unified, standardized work path of biodiversity
conservation planning. This study took Tongcheng County as an
example to verify the feasibility of the work path, optimize the
construction method of habitat network for biodiversity protection,
and provide a scientific basis for the planning of the county green
space system and biodiversity protection. |
