| Abstract: |
| The scientific identification of ecological sources and
reasonable construction of green infrastructure (GI) networks are
important measures to maintain the stability of the ecosystem and
promote the green transformation of resource-based cities. Based
on the perspective of regional differentiation, taking the main urban
area of Daqing as an example, through the collaborative use of
the landscape index method and the risk "source-sink" method,
the regional ecological sources of Datong District, Honggang
District, Longfeng District, Ranghuru District, and Saertu District
are identified.Based on the principle of multi-level network
construction, the least-cost path (LCP) method is used to generate
urban ecological corridors, integrate the spatial structure of multilevel corridors, and optimize the GI network layout of the main
urban area of Daqing. The results show that the combined use of the
regionally differentiated source selection method and the multi-level
network construction method fits the peculiarities of local research
and improves the traditional layout of uneven source distribution
and network structure bias among the various districts of resourcebased cities, and makes up for the connectivity of ecological sources
at the regional scale and the sustainability of urban ecological space
