 note = {本研究では,森林の蒸発散が基底流出に与える影響について検討した。基底流出の逓減は被圧逓減,不圧逓減に大別され,それぞれ指数関数,分数関数で表現することができる。これらを大洞沢に適用した結果,双方の関数ともかなりよい適合を示した。基底流出の逓減を表す関数は従来,蒸発散を考慮しないことが前提であったが,本研究の結果,季節変化を示し,蒸発散との関連があることを示唆した。逓減係数の季節変化は樹木の肥大成長,樹液流量の季節変化と同じ傾向を示しており,基底流出には蒸発散量が大きく関与していることが明らかとなった。大洞沢の場合,季節ごとの逓減係数は樹木成長の休止期を1とすると成長期には2.4倍,成熟期には1.8倍に増大した。また,各逓減係数と蒸発散量との間には強い相関が見られた。, This study investigated and analyzed the influence of evapotranspiration of forest on base runoff. Depletion of runoff can be classified as pressure depletion and non-pressure depletion according to various depletion coefficients. Generally, pressure depletion follows an exponential function, while non-pressure depletion follows a fractional function. Depletion of base runoff of the Ohora watershed fits an exponential as well as a fractional function very well. Generally, although depletion coefficients of the function do not take evapotranspiration into consideration, each depletion coefficient indicates the impact of seasonal variation on base runoff, and correlationship with evapotranspiration is suggested. Seasonal variation of the depletion coefficients accords with seasonal variation of the growth and sap flow of trees. Therefore it becomes clear that there exists very significant correlationship between evapotranspiration and base runoff. In addition, when a depletion coefficient associated with the resting stage of tree growth is assumed to be 1, that for the growing stage becomes 2.4 times and that for the maturation stage 1.8 times. By analyzing the relationship between depletion coefficients and evapotranspiration very significant correlationship is found between them., E, 3, KJ00004019095, 論文, Article},
