1. Input of acid deposition to forests(1) Input of acid deposition to forests was observed at various environments(2) Observation of dry deposition was started2. Throughfall, stem flow and soil(1) Seasonal fluctuations and difference in tree species were examined on pH, EC and dissolved ion(2) Neutralization process of acid deposition was examined on stands of Japanese cedar, Japanese cypress and so on(3) Reaction of plants and changes in vegetation were examined in relation to changes in soil environment3. Stream water's characteristics(1) Stream water's characteristics were examined at several watershed(2) Process of mineral output from forests was examined(3) Changes in water characteristics and mineral expenditure, were examined at snowy region in relation to snowmelt4. Methods for collecting depositions(1) Methods for collecting throughfall and stem flow were rediscussed(2) Methods for collecting dry deposition and soil solution were discussed(3) working group were organized to discuss methods for collecting depositions(4) Manual was made for acid deposition's observation5. Simultaneous observations(1) Simultaneous observations of wet deposition, dry deposition, throughfall of Japanese cedar, stem flow and stream water were conducted6. Data base(1) Methods for creating data bases from data collected in this research were discussed(2) Data base was created using data of simultaneous observations

1. 酸沉降对森林的输入(1)观测不同环境下的酸沉降对森林的输入(2)开始干沉降观测2。(1)考察了不同树种的pH、EC和溶解离子的季节波动和差异；(2)考察了杉木、柏木等林分的酸沉降中和过程；(3)考察了植物的反应和植被的变化与土壤环境变化的关系。(1)研究了几个流域的溪流特征(2)研究了森林矿物输出过程(3)研究了雪区与融雪有关的水特征和矿物消耗的变化。沉积物的收集方法(1)重新讨论了通流和干流的收集方法(2)讨论了干沉积物和土壤溶液的收集方法(3)组织了沉积物收集方法讨论工作组(4)编制了酸性沉积观测手册5。同时观测(1)同时观测湿沉降、干沉降、杉木通流、干流和溪水。(1)讨论了利用本研究收集的数据建立数据库的方法(2)利用同期观测数据建立数据库
