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).

提出了一种由山区造成的水资源需求和供应的定量评估方法。然后，通过方法和山区对水资源的作用进行了研究（Mitsuno）。在穆特地区管理的观点，三个农业生产系统（农业生产法律人物，农场工作合同中心和合成中心）进行了分析（Ozaki）（Ozaki）（Ozaki）。保水特性（Miyaushi）。还研究了沸石混合对土壤保留水分的改善的影响（Sakurai）。在GIFU县新开发的高地田地和有效的泥土保护技术（Amaya）中，研究了一种影响高地土壤衰老的因素（AMAYA）。石膏应用对减少土壤侵蚀的影响在现场图和实验室中进行了测试。石膏超过30kg/10a，将土壤侵蚀减少30％（Akae）。从考虑其菌落形成和生命强度之后，选择了杂草种类的杂草种类来覆盖山区农业区域的斜坡草。此外，还发现了可用于水污染指标的杂草物种（OKI）。进行了问题研究，以调查居民对灌溉管的意识作为景观因素。用居民的特征和运河的水质（OHTA）分析了结果。
