摘要: One-year field measurements were conducted in a Japanese cedar (Cryptomeria japonica) forest, located Gunma Prefecture, Japan. On the basis of meteorological and atmospheric concentration data, dry deposition SO2, HNO3, NO2 HCl was estimated using inferential method. The annual H+ at 721 eq ha−1yr−1, which 40% larger than measured wet (514 ha−1yr−1). Therefore, is an important pathway for input to forest study site. contribution each gas as follows: 25%; 32%; NO2, 10%; HCl, 33%. extremely high appeared be caused by emission intensity due waste incineration site region. differences between throughfall stemflow indicated that about 80% total taken up canopy.
