Constructing Ecological Security Pattern for Sinvsi Hub Region of the Grand Canal Based on Blue-Green Infrastructure
The Grand Canal has long been affected by the construction of human settlements,and the resulting water conservancy projects have affected the maintenance of regional ecological security.The paper takes Sinvsi hub region,the vital water conservancy hub project area of the Grand Canal,as the research object,to collect and analyze the regional blue-green infrastructure data based on the land data in 2023 through morphological spatial pattern analysis,landscape connectivity evaluation and minimum cumulative resistance model.In the region,16 ecological sources,15 key potential ecological corridors and 105 general potential ecological corridors are identified.The regional ecological security pattern of'one core,two centers,three belts,four axes,and multiple nodes and corridors'is constructed.The paper puts forward suggestions for optimizing the ecological security pattern based on the regional master planning and landscape spatial characteristics,i.e.,enhancing ecological resilience through blue-green integration,establishing a diverse protection system,and breaking down administrative boundaries for optimal management.The relevant results can provide an evidence base for the protection of cultural heritage and eco-environment protection and restoration in the Grand Canal hub area,and provide references for land spatial planning and ecological civilization.
