    昨年の報告に引き続き、森林施業が渓流水質に与える影響を評価するため、北海道北部にて操作実験を行った。欧米における既往の研究とは異なり、皆伐処理に伴う渓流水への硝酸イオンの流出は認められなかった。これに対し、掻き起し区では処理を行なってから3年後に硝酸イオンの流出が認められた。表土戻し区では処理直後に硝酸イオン濃度が約4倍上昇した。表層における土壌水の硝酸イオンは、処理後1年間は高濃度であったが、3年後には森林区と同程度に戻っており、草本の成長に伴う表層の硝酸イオンの吸収が原因と考えられる。一方、土壌中の硝酸イオン濃度が上昇するのに伴い、マグネシウムイオンやカルシウムイオン濃度も上昇したが、これらのイオンは渓流水質に影響を及ぼさなかった。また、豪雨時における渓流水の硝酸イオン濃度は水位低下後、掻き起し区は速やかに濃度低下を観測し、表土戻し区は数日間高濃度の継続が認められた。表土戻し処理によって、高濃度の硝酸イオンが地下深部で広範囲に滞留し、速やかに渓流水中に流出しやすい状況であることが示唆された。以上の結果を元に、森林施業に伴う渓流水質の変化を溶存イオンに着目した議論の結果を報告する。

    著者らは、北海道の2つの集水域について、渓流水のpHの時空間変動と、その変動を引き起こす要因について評価した。1つの集水域は、渓流の流路沿いに湿地が広がり、もう1つは狭い渓畔域を持つ。著者らは、渓畔湿地が渓流水のpHに及ぼす影響についても評価した。本研究では、渓流水のpHはほぼ中性で、主に二酸化炭素分圧(以下、pCO2)によりコントロールされていた。つまり、渓流水・渓畔帯からのCO2の脱気により、高いpCO2と低いpHを示す湧水から低いpCO2と高いpHを示す下流の水に徐々に変化していった。流路周辺の地下水は、渓流水よりも高いpCO2と低いpHを示した。地下水の流入により渓流水量が増加するが、渓流水のpHには明瞭な影響を示さなかった。このことは、土壌と渓流の境界面で比較的速やかなCO2の脱気が起こることを示唆する。広い渓畔湿地を持つ集水域は、高いpCO2と低いpHを示す小さな支流を有し、この支流が直接的に渓流水を酸性化した。融雪期にこの支流の流量が高くなったとき、高いpCO2を持つ支流が多量に流入するために、流下に伴う渓流水のpH上昇傾向が一時的に逆転した。

    We evaluated the spatial and temporal variations of stream pH and the factors causing the stream pH variations for two watersheds in northern Japan. One watershed has a wetland extending along the stream channel, and another a narrow riparian area. We also evaluated the effect of a riparian wetland on the stream pH. Stream pH in the present study was nearly neutral, and was controlled mainly by CO<SUB>2</SUB> partial pressure (hereafter, pCO<SUB>2</SUB>) in stream water; stream water gradually changed from spring water having high pCO<SUB>2</SUB> and low pH to downstream water having low pCO<SUB>2</SUB> and high pH through CO<SUB>2</SUB> degassing. Groundwater around the stream channel had a higher pCO<SUB>2</SUB> and lower pH than the stream water. Although the groundwater inflow increases the stream flow, it had no obvious effect on stream pH, suggesting the relatively rapid degassing of CO<SUB>2</SUB> at the soil-stream interface. The watershed having a broad riparian wetland had a small tributary with high pCO<SUB>2</SUB> and low pH, and this tributary directly acidified the main stream. When the flow of this tributary was high during the snowmelt, the longitudinal increase of the stream pH was temporally reversed because of the abundant inflow of the tributary having high pCO<SUB>2</SUB>.

    The inorganic nitrogen pool in soil, soil microbial biomass, nitrogen pool in vegetation and microbial nitrogen mineralization in soil were investigated to understand the effect of treatment for land surface by scarification on soil nitrogen dynamics in a forest ecosystem located in northern Hokkaido, Japan. The nitrate pool in the soil after scarification was higher than those in the control site during 1〜3 years after the treatment, and tended to decrease with the years. The increment of the soil nitrate pool during the initial 3 years after the treatment was caused not only by the decrease of nutrient uptake by vegetation, but also by the decrease of immobilization of soil nitrogen due to the decrease of soil carbon as an energy source for soil microbes. The temporal decrease of the soil nitrate pool in the initial periods after the treatment appeared to be caused by the leaching of nitrate from soil due to the rainfall and snow melting because nitrogen uptake by vegetation was small during these periods. Uptake of nitrogen by vegetation was an important factor for the temporal decrease of the soil nitrate pool about 4 years after the scarification. Net nitrification in the soil 5 years after the scarification was still higher than that in the control site, indicating that the effect of the scarification on soil nitrogen dynamics was maintained in the studied time scales.

    北海道演習林拓北流域及び福岡演習林御手洗水流域において,2005年6月-2006年6月にかけて降水,渓流水を採取・分析し,各流域における大気質や基岩等の立地環境の違いが降水や渓流水の化学成分に及ぼす影響について検討した.拓北流域では,降水,バルク降水,渓流水を採取し,御手洗水流域では,バルク降水,渓流水を採取した.拓北流域では,バルク降水のpH値が降水と比べて高かった.水素イオン以外のイオン成分濃度は,降水と比べてバルク降水で上昇しており,特にCa^(2+),NH_4^+の上昇が顕著であった.このイオン成分濃度の上昇の原因は,無降雨期間におけるガス状,粒子状物質のロート上への乾性沈着によるものと思われた.pH上昇の原因として,乾性沈着によるアルカリ土類金属やアンモニアの溶解が考えられた.バルク降水のNH_4^+濃度やNH_4^+沈着量は御手洗水流域と比べて拓北流域で高く,NO_3^-,SO_4^(2-)沈着量は拓北流域と比べて御手洗水流域で高い結果となり,大気質による違いを反映していた.バルク降水のpHは,御手洗水流域で4.5,拓北流域で5.3であり,御手洗水流域において顕著に低かった.その原因として,御手洗水流域において大気汚染に由来するNO_3^-,SO_4^(2-)濃度が高まっていること,拓北流域ではバルク降水中のNH_4^+,K^+,Ca^(2+)濃度が御手洗水流域よりも高いためと考えられた.渓流水のNO_3^-,SO_4^(2-)濃度は,拓北流域と比べて御手洗水流域において顕著に高い値を示した.その原因として,御手洗水流域においてNO_3^-,SO_4^(2-)沈着量が拓北流域と比べて高いためと考えられた.また,拓北流域では,K^+濃度が高く,御手洗水流域では,pH及びMg^(2+)濃度が顕著に高かった.この違いは基岩の違いが反映していると考えられた.御手洗水流域における渓流水のpHとMg^(2+)濃度には有意な正の相関がみられた.The effects of air quality and bedrock on the characteristics of precipitation and streamwater chemistry at the Takuhoku Experimental Watershed (TEW), Ashoro Research Forest, and Ochozu Experimental Watershed (OEW), Kasuya Research Forest were investigated from June 2005 to June 2006. Precipitation, bulk precipitation, and streamwater were collected at TEW and bulk precipitation and streamwater were collected at OEW. The results showed that the annual pH value of bulk precipitation was higher than that of the precipitation at TEW. Annual concentrations of major ions except for H+, especially Ca_2^+ and NH_4^+ , in bulk precipitation were higher than those of precipitation due to gaseous and particulate dry deposition during non-precipitation. This result implies that alkaline earth metals and atmospheric ammonia are the major cause of the increase in pH value in bulk precipitation at TEW. NH_4^+ concentration and deposition of bulk participation were higher at TEW than those at OEW, whereas NO_3^- and SO_4^(2-) deposition were higher at OEW than those at TEW, indicating the effect of air quality. The annual values of pH in bulk precipitation were 4.5 and 5.3 at OEW and TEW, respectively. The difference between the watersheds could be caused by the higher concentrations of atmosphericallyderived NO_3^- and SO_4^(2-) in bulk precipitation at OEW and the higher concentrations of NH_4^+, K^+, Ca^(2+) in bulk precipitation at TEW than those at OEW. Concentrations of NO_3^- and SO_4^(2-) in streamwater were considerably higher at OEW than those at TEW. This could be caused by the higher deposition of NO_3^- and SO_4^(2-) at OEW than those at TEW. As well, higher pH and Mg_2+ concentrations in streamwater were found at OEW than at TEW, whereas K+ concentration was higher at TEW than at OEW. This could be due to the different bedrock type between TEW and OEW. A significant positive relationship was found between pH and Mg^(2+) concentration in streamwater at OEW.

    Biogeochemical processes are closely related to ecosystem functioning and the change in stream chemistry against various environmental changes. A process-based model that replicates the interaction between biotic and abiotic factors is a powerful research tool in improring our understanding the environmental drivers of temporal and spatial fluctuations in biogeochemical cycling and predicting future changes in ecosystem functioning. In this paper, we review the general concepts, structure and applications of the existing process-based model, FOREST-BGC, CENTURY, TEM and PnET. We applied the PnET-CN model in a natural forest watershed in northern Hokkaido, Japan to assess the performance of the model and the problems encountered in improving its application. The PnET model is a generalized, lumped model based on the physiological processes of photosynthesis and evapotranspiration. Predicted seasonality in stream nitrate concentrations using the PnET-CN model was in general agreement with the observed values in Uryu Experimental Forest, Hokkaido University, despite a minor over-prediction during the winter and under-prediction in the non-snowy period. Analysis of the model's structure and validation suggested the need for modifications, including (i) the accumulation and melting process of atmospheric nitrogen deposition in the snowpack, and (ii) the effect of hydrological processes on the ground.

    A distributed hydrological model instead of a lumped model has been proposed as the most important tool in enabling the sharing of water information. In essence, a distributed model consists of sub-basins of tributaries and a main river channel. As for the latter, commercial models are available based on advanced mathematical techniques for hydraulic calculations. However, the methodologies for the description of rainfall-runoff phenomena from sub-basins have not been fully discussed. Especially for forested areas two key topics need to be addressed. The first is how to continuously describe runoff phenomena over several rainfall events and dry periods for further improving water quality simulation. The second is the serviceability of a model for the identification of its parameters via the measurable soil conditions of a sub-basin. To address these issues, the authors propose a new rainfall runoff model, the Yamashita Model, based on the assumption that the retention capacities of the soil have a significant effect on runoff phenomena. This model consists of a two-step retention and three-step runoff mechanism. This model is basic parameters includ the retention capacities of soil pores, which were identified by the measured volumes of the soil pores based on the classification by Takeshita, which distinguishes the retention capacities of a soil by its suction force. They examined this model using the actual rainfall-runoff data of two small catchments in the Uryu Experimental Forest of Hokkaido University, Japan. The simulation results generally agreed with the observed data. To improve rainfall runoff models, future long-term observations of rainfall and runoff should be conducted at various types and sizes of watersheds.

    北海道北部の近接する第三紀層と蛇紋岩の山地源流域において1997年と1999年に融雪流出の観測を行なった。その結果、蛇紋岩流域は流量変動が大きい特徴を有すること、それに対して第三紀層流域は流量変動が小さいことがわかった。蛇紋岩流域の極大流量は第三紀層のそれの約2倍だった。1日もしくは2日単位の水収支解析を行なったところ両流域とも流出率は100%以上だった。経験的な手法で直接流出を分離し、その流出率を調べたところ、第三紀層流域は30%未満、蛇紋岩流域では40%以上で60%を超える場合もあった。河川水温の平均値は第三紀層流域が約5℃、蛇紋岩流域が約2℃で3℃ほどの差があった。これらの値は、第三紀層流域では100cmよりも相当深い深度、蛇紋岩流域では50cm深の地温に等しい。このことから、第三紀層流域では土壌の深部に、蛇紋岩流域では浅層部に流出経路があると推測した。

    Extensive research on forest stream water chemistry gives important information in understanding the effects of environmental changes in forest ecosystems. The chemical properties of stream water from 45 forested watersheds in university forests over Japan were investigated in June, 1998. The average pH was 7.1 (maximum 8.1,minimum 6.1). The average electric conductivity (EC) was 64 (maximum 178,minimum 19) μS/cm. The EC of stream water in Okinawa and Sado Island sites tended to be high because the effects of sea salt. Except for the island sites, EC had a positive correlation with pH, summation of cation and alkalinity (mostly HCO_3^-). This suggests that the water showed a high EC value and a high pH value caused by the consumption of proton (H^+) in streams where carbonate weathering brings a high cation concentration. The NO_3^- concentration in the Kanto mountainous region sites was high compared with the concentration of other sites. In Gunma sites, the relationships between NO_3^- and Ca^<2+> concentration had a close positive correlation. It was considered that exchangeable Ca^<2+> in the surface soil was discharged due to the increase of H^+ produced by nitrification.

    The chemical composition of snowfalls in the Teshio Experimental Forest Hokkaido University in northern Hokkaido was investigated from December 1990 to March 1995. Although there was no industrial source of acid pollutants around the study area, most of the snowfalls observed were "acid snow". with pH valnes less than 5.6. The pH values of snofalls after cyclones were lower than those before cyclones. Snow were brought from W in the Japan Sea side and from N in the Okhotsk Sea side, the former is important to monitor acid pollutants which are likely to be transported from the Chinese mainland.<BR>Although non-seasalt SO<SUB>4</SUB><SUP>2-</SUP> was relatively rich in the snowfalls in the Japan Sea side, there was no difference in pH of snowfalls with different wind directions. The presence of non-seasalt Ca<SUP>2+</SUP>in the Japan Sea side snowfalls suggested that the acidity of snowfalls was partly neutralized by the soil particles in the air, such as loess particles, covering over the Continent.

    A foliar extraction method using potted young trees was studied and its feasibility was tested in the field. The leaching process of polluted sample trees was described well by a two-component exponential equation. The first component was characterized by very high initial concentration and the larger value of attenuation coefficient and, moreover, it was not observed when sample trees were kept in a clean atmosphere. It was apparent that the first component is caused by the leaching from "external" sources and can be regarded as a measure of dry deposition rates. To reduce the effect of "internal "source, the amount of leaching water has to be reduced as much as possible. In the case of small young trees, the "external" was almost completed by spraying 1.25 L plant^<-1> of water, 6-10 mm in water depth. It was also noticed in the field observation that very frequent extractions accelerated dry deposition due probably to changes of leaf surface characteristics, e.g. wettability and erosion of wax and/or cutin layers. A relatively long averaging period of more than 10 d was recommended to avoid overestimation due to the acceleration effects. The variation of dry deposition rates due to the shape and size of sample trees were dependent closely upon the leaf area index and crown basal area, and more than 80% of it was explained by these two parameters. The field tests were successfully conducted at Tomakomai and Teshio. For the most pollutantions, especially for anthropogenic ones, dry deposition rates at Tomakomai were apparently higher than those at Teshio but their proportions to bulk deposition rates were less than 15% at both sites.

    Continuous observations for the winter discharge were carried out at 7 small basins in the mountain of cold and snowy area, such as northern Hokkaido. The discharge of the basin was measured by covering gauging weir with falling snow to avoid freezing. Although the air temperature around the weir dropped to about -30°C, the data for the discharge were obtained succesively without the trouble caused by freezing. Succesive discharge was observed from the basin throughout winter season from mid-December to mid-March (70-100 days). The diurnal change of the discharge by evapotranspiration was obscure in the recession curve of winter discharge. The discharge became near constant in the latter half of the observation period. The value of the constant discharge and the duration to reach such discharge cleary depended on the surface geology of the basin (0.8-1.2mm/day and 10 days for the basin of serpentine rocks, and 0.3-0.8mm/day and 30-40 days for that of tertiary rocks, respectively). Therefore, it can be said that the winter discharge in the snowy and cold area directly reflect on the hydrological character of the basin.

    北海道北部地域を対象に,厳冬期における渓流流出と森林の影響に関する観測を行っている。本報告では,強風寒冷地の典型とされる宗谷丘陵での観測結果(1989-1990年・1990-1991年・1991-1992年の3冬期中心)をもとに,森林の流域的規模での堆雪効果と厳冬期流出に与える影響について報告した。観測流域は,草地70%・ササ地30%のサンナイ川と,針広混交林が70%/草地30%のオテンナイ川の源頭域である観測流域の面積は,サンナイ川10.4haとオテンナイ川11.6haである。流域の方向も同じようになるように選定し,この観測流域ではほぼ北西向きになっている。また,丘陵地帯であるため,流域の源頭部は標高85mから90mと,両流域は同じ高さにある。地質は,両流域とも第三紀層である。寒冷・強風地における積雪は,再移動もともない,沢などの地形的な低地に集中的に堆積する。したがって,尾根部の積雪は極端に少なくなる。このような堆雪傾向においても,森林は積雪を貯留する効果をもち,尾根部の森林内でも沢底と同じかそれ以上の積雪を蓄えている状況が観察された。このような状態は流域的規模においても同様であり,森林の多いオテンナイ川流域では草地化されたサンナイ川流域より,平均積雪深で2倍,積雪推量では4倍以上の積雪を蓄えていた。また,サンナイ川のように積雪の少ない流域では,60%以上の面積の表土が凍結していた。オテンナイ川のように,林内や窪地(沢底)に積雪が多く貯留される流域においては,表土の凍結が防止されていた。表土の凍結の発生域は,源頭尾根部の草地化された部分だけであり,最大でも流域の16%ほどであった。表土凍結の発生が防止されるためには,積雪移動の多発する地域においては,約50cmの積雪深が必要と判断された。50cm以上の積雪深があり,表土凍結の発生していない地域においては,積雪下面での融雪現象も観察された。また,オテンナイ川のように表土凍結面積の少ない流域の厳冬期流出量は,表土凍結面積の多いサンナイ川流域の1.5倍から3倍をこえる値になっていた。表土凍結面積の多い流域では,それだけ地表への水分供給量が少なくなることから,流出量の差は表土の凍結に影響されていると判断された。したがって,強風寒冷地における森林は,堆雪効果を発揮し,表土凍結を防止することで,厳冬期の渓流流出にも大きな影響をあたえていると考えられた。
