Summary of this study is as follows.1) Probability density function (P.D.F.) was investigated using the rainfall data at 6 sites in Japan. The result shows that the accuracy was not so different between each type of P.D.F. from the viewpoint of prediction and unified regression line could be made for all durations of rainfall and all sites.2) It was attempted to clarify the temperature differences between several big cities and their surrounding small towns. The result shows that the outstanding characteristics of hourly changes of temperature differences were clarified.3) It was analyzed the temperature differences between capital cities of prefectures and their surrounding small towns using multiple regression analysis. The result shows that the phenomena of heat island was evaluated.4) It was evaluated influence of land use to the phenomena of heat island using multiple regression analysis. The result shows the relationship between temperature and land use around the point that temperature was measured.5) Water quality in rain was measured. Concentrations of the parameters related to acid rain were high in summer. Concentrations of the parameter related to neutralization were also high in summer.6) It was investigated the existing condition of outflow of nitrogen nutrients from upland soil. Fundamental physical properties and soil solution quality of upland soil and water quality of outflow from upland soil were tested.

本研究的主要内容如下：1）概率密度函数（P.D.F.）在日本的6个站点的降雨量数据进行了调查。结果表明，不同类型的PD F的精度相差不大。从预报的角度出发，可以对所有的降雨历时和所有的站点作出统一的回归线。2）试图弄清几个大城市与其周围小城镇的温度差异。结果表明，各地级市气温逐时变化的显著特征。3）采用多元回归分析方法，对地级市省会城市与周边小城镇的气温差异进行了分析。结果表明，研究区的热岛效应得到了有效的评价。4）利用多元回归分析方法，评价了土地利用对热岛效应的影响。结果表明，温度与测点附近土地利用的关系。5）雨水水质测定。与酸雨相关的各参数浓度在夏季较高。6）研究了高地土壤氮素流失的存在状况。测定了高地土壤的基本物理性质、土壤溶液质量和旱地出水水质。
