The water quality in rainfall, throughfall, stemflow and litterthrough in the Larix gmelinii plantation at Eastern Mountainous Region in Heilongjiang Province had been studied. The indicator included pH, Do, TURB, TDS, COND, ORP, K, Na, Ca, Mg, Cu, Zn, Mn and Fe. The results showed that the chemical properties of rainfall had been changed after it passing through forest canopy. PH value of litterthrough was higher than throughfall and stemflow every month, and the stemflow showed significant acidification especially. The trend of Do in the throughfall was the same as rainfall. The COND and TDS of throughfall, stemflow and litterthrough were higher than rainfall every month. The content of K changed significantly and the average of K of five months was in the following order: stemflow>; litterthrough>; throughfall>; rainfall. The contents of Ca and Mg were in the following order: litterthrough>; stemflow>; throughfall. The trend of Zn element in the rainfall was the same as throughfall, stemflow and litterthrough. The net leaching of Zn and Fe in the throughfall was low. The leaching coefficient of throughfall was in the following order: Cu>; K>; Mg>; Mn>; Ca>; Na>; Fe>; Zn. The leaching coefficient of stemflow was in the order of Mn>; Mg>; Fe>; K>; Cu>; Ca>; Na>; Zn. And the leaching coefficient of litterthrough was in the following order: Mg>; K>;Ca>; Cu>; Fe>; Mn>;Na>; Zn.
