The ecological security pattern plays a crucial role in maintaining ecosystem health and ensuring security. establishment of the Mudanjiang City can provide scientific basis effective support for stabilizing environment, mitigating regional human–land conflicts, rational land- use planning. This paper utilizes theory constructing an using source-resistance plane-corridor node to grade importance source areas based on connectivity index. It combines morphological spatial analysis PLUS model generate identify present value 2022 City, as well predict eight land types seven landscape under three development scenarios by 2032. A transfer matrix transfer-intensity map are introduced explore structural characteristics transfer, while four fragmentation indexes combined with principal component coefficient variation method form comprehensive different classes. Finally, 2022, is developed that establishes logical connections between land-use structure, types, transformation mechanism, sources. results follows: (1) In 23 areas, 65 corridors, 66 nodes were extracted. overall shows “U” shape openings northeast. (2) cumulative weight economic social factors resistance surface reached 51.36%. (3) response degree forest primary tertiary was highly significant, R values reaching 0.9675 −0.8746, respectively. comparative study comprehensively showed best scenario sustainable future priority scenario, where area smallest proportion but strongest disturbance fluctuation becomes key affecting City.
