Data used for ecological network construction and simulation

<b>1.Land use data</b> was derived from the 2023 version of <b>SinoLC-1</b>. Based on mainstream large-scale land cover classification systems and Chinese landscape characteristics, the SinoLC-1 classification system defines 11 land cover types: <i>Arbor cover</i>, <i>Shrubland</i>, <i>Grassland</i>, <i>Cropland</i>, <i>Buildings</i>, <i>Transportation routes</i>, <i>Sparse or barren vegetation</i>, <i>Ice and snow</i>, <i>Water</i>, <i>Wetlands</i>, and <i>Mosses and lichens</i>. In this study, “Buildings” and “Transportation routes” were aggregated into the category of <b>Built-up areas</b>, “Cropland” was categorized as <b>Cropland</b>, “Arbor cover” and “Shrubland” were combined into <b>Forest</b>, “Grassland” remained as <b>Grassland</b>, and “Water” and “Wetlands” were merged into <b>Water bodies</b>. “Sparse or barren vegetation” was categorized as <b>Unused land</b>, while “Ice and snow” and “Mosses and lichens” were not present in the study area and thus were excluded from analysis.<b>2.</b><b>Road data</b>, including railways, expressways, national highways, and major urban roads, were incorporated for both habitat quality evaluation and resistance surface construction.3.The <b>Normalized Difference Vegetation Index (NDVI)</b> was utilized in the construction of the resistance surface.<b>4.</b><b>Digital Elevation Model (DEM)</b> data were also employed to construct the resistance surface.<b>5.</b><b>The coded data</b> were used to simulate cascading failures.<br>
