To investigate and compare the effects of air pollution near Seoul on soil ion, plant nutrient contents and plant growth, 14 Quercus mongolica forests were studied from Mt. Namsan in Seoul to Mt. Maebongsan in Kangwon-Do along the line transect. Soil pH values decreased as approached to Seoul. Concentrations of basic cations such as exchangeable Ca/sup 2+/, Mg/sup 2+/ and Na/sup +/ and effective cation exchange capacity(ECEC) in forest soil decreased as approached to Seoul. Ca/sup 2+/ and Mg/sup 2+/ contents in l-year-old Q. mongolica twigs decreased, but their K/sup +/ and Na/sup +/ contents increased as approached to Seoul. Ca/sup 2+/ contents in l-year-old Q. mongolica leaves decreased, but their K/sup +/ and Mg/sup 2+/ contents increased as approached to Seoul. Length of l-year-old twigs generally decreased near Seoul. Tree-ring analyses of Q. mongolica trees in Mt. Namsan and Mt. Yebongsan showed that mean tree-ring width in Mt. Namsan was narrower than that of Mt. Yebongsan from early 1970's to late 1980's.
