Stepwise regression between Ln(Chl. a+1) and Ln(AT+1), Ln(SD+1), Ln(TN+1) and Ln(TP+1).

Lake	Stepwise model	Standardized beta	R²	P	VIF
Fuxian	Ln(Chl. a+1) = 1.066^*−54.118 Ln(TP+1)^	Ln(TP+1), −0.504	0.254	<0.05	1
Erhai	Ln(Chl. a+1) = 2.768^* + 3.326 Ln(TN+1)^−1.468 Ln(SD+1)^	Ln(TN+1), 0.493; Ln(SD+1), −0.437	0.790	<0.00001	3.090
Dianchi	Ln(Chl. a+1) = −17.481^* + 7.051 Ln(AT+1)^** + 1.35 Ln(TN+1)^*	Ln(AT+1), 0.524; Ln(TN+1), 0.372	0.577	<0.001	1.217

Chl. a, annual mean chlorophyll a concentration; AT, annual mean air temperature; SD, annual mean water transparency; TN, annual mean total nitrogen; and TP, annual mean total phosphorus.
