# Table 1 Descriptions of the selected landscape metrics. In this table, several metrics related to area and edge, shape, and aggregation categories have been presented that all of them measure landscape configuration aspects

Category | Metric | Equation | Range |
---|---|---|---|

Area and edge | Area-MN | \( \frac{\sum \limits_{j=1}^n{x}_{ij}}{n_i} \) | Area-MN > 0 |

ED | \( \frac{\sum {e}_{ik}}{A}(10000) \) | 0 ≤ ED, no limit | |

Shape | PAFRAC | \( \frac{\frac{2}{\left[\sum \limits_{j=1}^n{lnp}_{ij}-{lna}_{ij}\right]-\left[\left(\sum \limits_{j=1}^n{lnp}_{ij}\right)\left(\left(\sum \limits_{j=1}^n{lna}_{ij}\right)\right)\right]}}{\left(\sum \limits_{j=1}^n{lnp}_{ij}^2\right)-{\left(\sum \limits_{j=1}^n{lnp}_{ij}^2\right)}^2} \) | 1 ≦ PAFRAC ≦ 2 |

Aggregation | LSI | \( \frac{0.25\sum {e}_{ik}}{\sqrt{A}} \) | 1 ≤ LSI |

DIVISION | \( \left[1-\sum {\left(\frac{a_{ij}}{A}\right)}^2\right] \) | 0 ≤ DIVISION ≥1 | |

SPLIT | \( \frac{A^2}{\sum \limits_{j=1}^n{a}_{ij}^2} \) | 1 ≦ SPLIT ≦ number of cells in the landscape area squared | |

AI | \( \left(\frac{g_{ii}}{\mathit{\max}\to {g}_{ii}}\right)(100) \) | 0 ≤ AI ≥ 100 | |

NP |
n_{i}
| NP ≥ 1 | |

ENN |
h_{ij}
| ENN > 0 |
