Table 3. Regression results of relationships between the various driving factors and water resources after normalization. Contributions (%) represent the proportion of the total change in water resources accounted for by a given driving factor (Standard coefficient/Total absolute value of Standard coefficient).

	R2	Adjusted R2	Contribution (%)	Standard coefficient

Notes.

R² is the regression goodness of fit based on the value of each driving factor. Parameters with significant contributions to regressions were identified by repeated measures ANOVA.
