抄録

To clarify mechanisms of dry deposition in a forest, the vertical profiles of gaseous and particulate matter in a Japanese cypress forest in Kiryu experimental watershed, located in the southern part of Shiga Prefecture, Japan, were studied. From January 2000 to January 2002, gaseous and particulate matter were collected for 2 to 3 weeks successively using a 4-stage filter and pump system at 6 different locations above (30.0, 28.0, 21.0 m), in (14.0 m) and below (5.0, 1.2 m) the forest canopy. The ionic concentrations of the water-soluble constituents of particulate matter (Na⁺, NH₄⁺, K⁺, Ca²⁺, Mg²⁺, Cl^-, NO₃^-, SO₄^2-) and concentrations of some trace gases (HNO₃, HCl, NH₃, SO₂) averaged over 2 to 3 weeks were measured by ion chromatography. As a result of measurements, the concentrations of HNO₃, HCl, NH₃ and SO₂ were found to decrease at the canopy. The concentrations of inorganic ionic constituents of particulate matter below the canopy showed specific temporal variation being independent of the concentrations above the canopy. The composition of inorganic ionic constituents of the particulate matter did not change significantly among the measured heights. The particulate matter below the canopy seemed to be constantly supplied from the canopy by the resuspension of deposited particles because of stable wind below the canopy.
