Correlations between salinity and the rest of environmental variables in the different models and datasets (spring, summer, autumn, all seasons and validation).

P values are shown for significant Pearson correlations. Temp = temperature; O2 = Dissolved oxygen; tN = Total nitrogen; Tp = Total phosphorus; Secchi = Secchi depth; Cond = conductivity; Chl a = chlorophyll a.

显著皮尔逊相关系数（Pearson correlations）对应的P值（P values）已给出。其中，Temp为温度（temperature），O2为溶解氧（Dissolved oxygen），tN为总氮（Total nitrogen），Tp为总磷（Total phosphorus），Secchi为塞氏盘深度（Secchi depth），Cond为电导率（conductivity），Chl a为叶绿素a（chlorophyll a）。
