jismart2024019: Optimization of Ecological Networks in the Hilly Area of East Shandong

Abstract

The hilly area of east Shandong has experienced rapid urbanization and industrialization in recent years, which has resulted in the expansion of construction land, habitat fragmentation, and a decline in landscape connectivity. These developments have impacted species survival and ecosystem functions, jeopardizing the ecological balance and the region's ability to sustain itself. In this study, the models of InVEST, MaxEnt, Zonation 5, MCR, and Circuit Theory were extensively applied to thoroughly assess and analyze the ecosystem services, species habitat, ecological source areas, ecological resistance surfaces, and ecological corridors of the watersheds in the east Shandong hilly area. A total of 3017.6km² of ecological source areas; 257 first-level ecological corridors; 167 second-level ecological corridors; 95 third-level ecological corridors; 94 ecological critical points covering 52.7km²; and 93 ecological breakpoints covering 93.4km² were discovered. The establishment of the ecological network not only improves the connectedness of the ecosystem, but also provides a scientific basis for ecological conservation and restoration. Furthermore, it enhances the research domain of ecological network development, which relies on the circuit theory model. Moreover, it unveils the intricate nature and ever-changing patterns of the ecology in the area, offering vital hands-on knowledge for future scientific investigations.
