项目摘要

A quantitative evaluation method of water resources demand and supply caused by mountainous area was proposed. Then some examples were examined by the method and the role of mountainous area on water resources was discussed (Mitsuno).In view of moutainous area management, three systems for agricultural production (agricultural production legal person, farm work contract center and composit center) was analyzed (Ozaki).Mechanical strength of Masa soil, which covers widely the mountainous area of Chugoku and Shikoku District, was examined against degree of weathering and water retention property (Miyaushi) . The effect of zeolite mixing on improvement of water retention of the soil was also examined (Sakurai).A mechanism of aging and factors which affect aging of upland field soil were examined in newly developed upland fields in Gifu prefecture and effective soil conservation technics were discussed (Amaya). Effect of gypsum application on reduction of soil erosion was tested on field plots and in laboratory. Gypsum more than 30kg/10a decreased soil erosion by 30% (Akae).Several species of weeds were selected for covering grass of slopes in mountainous agricultural area from consideration of their colony formation and vital strength. In addition, weed species available for indices of water pollution were found (Oki).Questionare research was made to investigate residents'consciousness on irrigation canals as a landscape factor. The results were analyzed with the residents' characteristics and water quality of the canals (Ohta).

提出了山区水资源供需定量评价方法。然后，应用该方法对一些实例进行了检验，并讨论了山区对水资源的作用（Mitsuno）。（农业生产法律的人、农业劳动合同中心和商品中心）进行了分析（尾崎）。广泛覆盖中国和四国地区山区的Masa土壤的机械强度，针对风化程度和保水性（Miyaushi）进行检查。还研究了沸石混合物对提高土壤保水性的效果（樱井）。在岐阜县新开发的高地中，研究了高地土壤老化的机理和影响旱地土壤老化的因素，并讨论了有效的土壤保持技术（阿玛亚）。通过田间小区试验和室内试验，研究了施用石膏对减少土壤侵蚀的效果。施用石膏30 kg/10a以上，土壤侵蚀量减少30%（赤霉素）。从群落形成和生命力等方面考虑，选择了几种杂草作为山地农业区的坡面覆草。此外，还发现了可作为水污染指标的杂草种类（Oki）。为了调查居民对灌溉渠作为景观因子的意识，进行了调查。并结合居民的生活特点和运河（太田）的水质进行了分析。
