Abstract: |
Protected area network (PAN) plays an important role in
maintaining the ecological functions of the region and promoting
the sustainable development of the ecological space and built area.
In order to fully realize the conservation goal, it is necessary to
integrate the spatial distribution of multiple conservation features,
cost and other factors to carry out efficient and clear spatial planning
of various types of protected area in the PAN. This paper relies on
the systematic conservation planning (SCP) framework to explore
the planning of regional PAN. Taking Beijing as an example,
the mapping and spatial correlation analysis of biodiversity and
ecosystem service conservation features are made and 3 types of
conservation zones of different management goal were defined.
The spatial optimization algorithm tool Marxan with Zones was
used to distribute the conservation features in different zones of 3
scenarios, to maximize synergies between conservation features
while reducing trade-offs. The results show that compared with
the absolute ideal scenario, the strict conservation scenario, where
the conservation target is allocated to the adjacent zone is more
advantageous in improving the achievement rate of the conservation
target and promoting the synergies between the conservation
features. This research can serve as an effective basis for the
construction of the regional protected area network. |
