资源简介：
The human influence intensity (HII) index proposed by Sanderson et al., (2002) was used. We applied a road distance map (https://www.openstreetmap.org/), a grided population density map from 2015 (1 km × 1 km) (https://www.resdc.cn/), nighttime lights from 2018 (500 m × 500 m) (https://dataverse.harvard.edu/) (Chen et al., 2020) and land use data from 2020 (30 m × 30 m) (http://www.globeland30.org/) to generate the HII at 500 m × 500 m. We assigned scores to population density, roads and railways, land use/ cover, which were summed to quantify the HII, which ranges from 0.05 to 30
