Table 2 Threat factors and their stress intensities.
From: Spatiotemporal evolution of land use and habitat quality in the Three-River source region
Threat factor | Longest threat distance (km) | Weight | Spatial decay type |
|---|---|---|---|
Cultivated land | 1 | 0.6 | Linear decay |
Construction land | 8 | 0.8 | Exponential decay |
Unused land | 3 | 0.5 | Linear decay |
