摘要：
The Bear Brook Watershed in Maine, USA is the site of a paired watershed study. West Bear (WB) catchment is being artificially acidified with 1,800 eq ha-1 y-1 of (NH4)2SO4. East Bear (EB) serves as the control. After six years of artificial acidification, volume-weighted concentrations in WB, normalized to EB, increased approximately as follows, in μeq L-1 : H+, 15; Al (umoles), 50; Al (μeq L-1), 100; Ca. 50; Mg. 20; Na, 10; K, 2; SO4, 120; NH4, 2; NO3, 80; HCO3 has decreased 10 μeq L-1. Based on changing chemistry, several inferences can be made about soil-soil water interactions.
