説明
Two types of the chemical changes of streamwater during storm runoff were found: Type I which recovers approximately the same concentration in the recession limb as the baseflow level prior to the runoff event; Type II which overshoots the baseflow level. Main solute belonging to Type I is SiO2, and that to Type II is NO3--N.<br>To relate the element cycle in forest ecosystem to the streamwater chemistry, element content in forest soil was analyzed. This proves that silicon content in forest surface soil is somewhat lower than in deeper soil, while nitrogen becomes greatly enriched in surface soil. Besides, the difference between element contents in soil makes a change of vertical soilwater chemistry in SiO2 and NO3--N concentrations, and consequently generates the chemical changes of streamwater through soilwater leaching.
