Study on the Structural Properties of an Ecospatial Network in Inner Mongolia and Its Relationship with NPP

In the context of strengthening construction ecological civilization and accelerating “carbon peak” in China, regional pattern its connection with carbon sink capacity have become an urgent topic. Given that Inner Mongolia is a large emission province conflict between economic development protection particularly prominent, we took as example to extract ecospatial network, then calculated integrity index, topological indices, recovery robustness network evaluated other properties structure by combining them background. addition, analyzed relationship indices net primary productivity (NPP). The results showed was scale-free heterogeneous, low integrity, connectivity stability, which were focus future optimization. nodes important functions mainly distributed farm-forest ecotone, grasslands, agro-pastoral ecotone; under simulation attack, node stronger than corridor robustness, NPP negatively significantly correlated woodland grassland nodes. terms restoration, unused land west key area, it necessary add new corridors. enhancing sequestration capacity, premise ensuring connectivity, appropriate rational merging corridors within woodlands grasslands effective means. This study provides reference for evaluating optimizing areas prominent problems improving ecosystems their structure.
