Fig. 5: Interpretation of natural and anthropogenic impacts on changes in solutes with river syndromes.
From: Global syndromes induced by changes in solutes of the world’s large rivers
a, b Gibbs model for stations with solute-induced river syndromes under varying trends in water discharge (Q). The 60 dots in purple, blue, and yellow respectively represent decreasing, stable, and increasing trends in the annual runoff. c, d are latitudinal distributions of proportional areas of temperate climate type and urban land area. e, f are redundancy analysis (RDA) results for the influence on dissolved solids of natural factors (reclassification for Köppen climate and lithology) and anthropogenic factors (irrigation, population, degree of regulation (DOR), and detailed reclassification of land cover), in critical latitudinal belts.
