| Abstract: |
| The rapid urbanization has separated and isolated green
spaces that are habitats in urban areas, and consequently biodiversity
has been threatened greatly. The construction of a multi-species
habitat network based on urban green space is urgently needed
for the future biodiversity conservation and development. Taking
Fengtai District of Beijing City as a case area, this paper proposed a
compound model of Integrated Valuation of Ecosystem Services and
Trade-offs (InVEST) and Minimum Cumulative Resistance (MCR)
to construct urban green space habitat network for biodiversity
conservation and green space development. It included selecting the
focus species oriented to habitat preservation in the region firstly,
next locating the habitat source patches based on the acquisition
of big data sources, then locating the habitat sink patches and
constructing the resistance surface based on the module of habitat
quality evaluation in the InVEST, and building up the urban green
space habitat network for Fengtai District by the model of MCR
lastly. The results depicted not only the status of habitat quality but
also the future blue map of urban habitat network development. The
compound model of InVEST and MCR might provide a method
reference of habitat network construction for urban green space
patterns planning. It is hoped that this framework of habitat network
construction could be a bridge between urban green space pattern
planning and biodiversity conservation in the context of spatial
planning of new era. |
