Landscape Dynamics and Ecological Risk Assessment of Cold Temperate Forest Moose Habitat in the Great Khingan Mountains, China

The change in habitat pattern is one of the key factors affecting survival moose population. study landscape to protecting Chinese cold-temperate forest population and monitoring global distribution moose. Through ecological risk assessment a forest, we hope assess strength resistance under stress factors. This provides theoretical basis for protection China establishment national park. In study, MaxEnt model, index calculation model construction were used analyze field survey infrared camera data from April 2014 January 2023. suitability layer Nanwenghe National Nature Reserve Great Khingan Mountains was calculated, range divided based on logical threshold model. calculated by Fragstats software established dynamic changes 2015 2020. results showed that premise warming, contagion decreased 4.53 split increased 4.86 terms risk: area low areas 0.88%; medium 1.11%; high 0.23%. fragmentation tends increase, preferred patch type dispersed, degree aggregation low, transformation increases. middle are mainly concentrated river its nearby forests, showing fine scattered distribution. Under interference warming human activities, trend increasing, quality declining, which likely cause migration. For this reason, author believes whole cold temperate face increasing dominant types coniferous region caused resulting an increase fragmentation. While reduced, it has significant impact diversity integrity ecosystem. references further research climate species related studies. It also helpful humans strengthen their awareness formulate reasonable sustainable development planning forests. Finally, effective forests dynamics.
