This study was carried out to investigate the percentage of the net precipitation in Korean Pine (Pinus koraiensis) stand separated by monthly, annually, the amount of rainfall and distance away from stem, at University of Sangii, Wonju, Kangwon province, during the period from April 1993 to October 1996. The average percentage of net precipitation showed 55.7% of the total precipitation, the minimum percentage of net precipitation was 45.7% in May and the maximum percentage was 62,9% in July. The average percentage of net precipitation at 0.3m far away from the stem showed 45.9% of the total precipitation and showed 60.3% at 0.6m distance, The average percentage of net precipitation within precipitation of 10mm and less showed 37.5% of total precipitation and showed 70.9% within precipitation of 100mm and over. The relationship between percentage of through-fall and total precipitation were highly significant. It was estimated to be Y(%)= 12.35LnX(mm)+9.45 (R2= 0.735**). The relationship between stemflow and rainfall was estimated to be Y(l)= o.27X(mm)-1.83 )+9.45 (R2= 0.921**). The relationship between percentage of net precipitation and total precipitation was estimated to be Y(%)= 13.79LnX(mm)+4.56 (R2= 0.946**) with significance at 1% level.
Key words: throughfall, stemflow, Korean white pine (Pinus Koraiensis S. et Z.)
