专家简介：Professor Chris Johnson conducts research on the chemistry of soils and water in forest ecosystems.He is actively involved in research on the chemistry of natural organic matter, which plays an important role in soil fertility, trace metal transport, and the acid-base status of soils and natural waters.Professor Johnson is also involved in the interdisciplinary study of biogeochemical cycles at the HubbardBrookExperimentalForest in the U.S.He has ongoing research interests in the fate of trace metals (Pb, Zn, Cu, Ni) in forest soils and landscapes; the effects of clear-cut logging on soils and drainage waters; and the changing acid-base chemistry of soils historically affected by acid rain.He is involved in an ambitious long-term project in which wollastonite, CaSiO3, was added to an entire watershed at Hubbard Brook in an attempt to replace Ca leached from the soil by acid rain. He has served as a visiting faculty member at CharlesUniversity in Prague and is an Adjunct Professor at GriffithUniversity in Brisbane, Australia. He has been an associate editor for the Soil Science Society of America Journal and the Journal of Soils and Sediments.
