文摘

We examined the difference in transport of Na, Mg, and Ca in headwater streams. Non-free ionic fractions relative to total element ranged from 0% to 70%. Non-free ionic fractions during a heavy rainstorm could be in bonding to humic substances. The metal bonding with humic substances was predominantly enhanced in the deciduous catchment. Differing vegetation and resultant hillslope hydrology was key to provide the different transport of major metals.
