Table 4 The importance of different environmental factors on the distribution of landscape pattern. Note: All fitted models exhibit R² values between 0.002 and 0.557 and pass the F-test (P < 0.05), indicating statistical significance. The tolerance levels of all variables are sufficiently high to avoid multicollinearity. Based on significance testing, the relative importance of variables helps explain the contribution of the CATREG model to the regression, with higher importance indicating greater influence.
