为了明确城市化对森林土壤化学特征的影响，研究了日本多马川盆地森林表层土壤的化学特征，包括(1)碳(C)浓度、(2)交换碱浓度、(3)阳离子交换容量（CEC）和(4)土壤pH。我们将道路比率定义为城市化水平。研究地点位于周围城市化水平不同的地区。表层土壤交换性碱（尤其是钙、镁）浓度、碱饱和度百分比和pH （H2O）随道路比的增加而增加；换句话说，随着城市化程度的提高，C和CEC与道路比率无关。观察到随着城市化的增加而增加的交换基的一个原因似乎是尘埃的沉积。交换碱浓度（和碱饱和度）的增加与土壤pH值的增加相对应。
In order to clarify the effects of urbanization on the chemical characteristics of forest soils, we investigated several surface soil chemical characteristics, including (1) carbon (C) concentration, (2) concentrations of exchangeable bases, (3) cation exchangeable capacity (CEC), and (4) soil pH of forests in the Tamagawa basin, Japan. We defined the road ratio as level of urbanization. Study sites were located in areas with varying levels of surrounding urbanization. Surface soil concentration of exchangeable bases (especially calcium and magnesium), percent base saturation, and pH (H2O) increased with an increasing road ratio; in other words, with increased urbanization, C and CEC were unrelated to road ratio. One reason for the observation of increasing exchangeable bases with increasing urbanization appears to be the deposition of dust. The increase in exchangeable bases concentration (and % base saturation) corresponds to increases in soil pH.
