Table 4 Significance of the partition of the coupling mechanism between the support index and the pressure index.
From: Evaluation of resource and environmental carrying capacity in rare earth mining areas in China
Partition state | \(0\le \mathrm{y}\le {x}^{2}\) | \({x}^{2}\le \mathrm{y}<\mathrm{x}\) | \(\mathrm{x}\le \mathrm{y}<\sqrt{x}\) | \(\sqrt{x}\le \mathrm{y}\le 1\) |
|---|---|---|---|---|
\(0 \le \mathrm{ x }\le 1\) | High-value Surplus area | Low-value Surplus area | Low-value Load area | High-value Load area |
