- •
The modified GWR models had higher R2 and reflected the actual spatial features.
- •
A manual variable excluding-selecting method is explored to avoid multicollinearity.
- •
Influences of the dominant indicator on water quality varied with space and seasons.
- •
Protection policies need consider site-specific conditions and seasonal variations.
