Abstract

Abstract: Nutrient elements in precipitation and throughfall are studied in a pine-spruce-fir forest of Changbai Mountain Natural Reserve. The amount of nutrient elements in throughfall is higher than that in precipitation, and their leached amount from canopy is in an order of K>Mg>Ca>N. From the viewpoint of nutrient return, throughfall plays a more important role in comparison to litterfall.

Key words: Nutrient elements, Throughfall, Pine-spruce-fir forest, the Loess Plateau, seasonal variation, vertical variation, mountain apple orchard, soil moisture
