The objective of this study was to investigate the system for upland irrigation planning at the field level and the farm level. To achieve it, the meteorological conditions and the evapotranspiration which were the reason of irrigation was measured, and the cause for the difference between the design water requirement and the actual situation of water requirement in a upland irrigation block was investigated.The investigation at farm level was conducted with using the data having been measured from 1993 in the Tohaku Irrigation Project district. The hourly and daily water use at every farm pond were analyzed. As a result, the investigations revealed that the amount of water use increased during long, clear, dry days, and the peak of hourly water use was almost the same amount as the design water requirement, and the peak discharge from the farm ponds was in the morning and evening.As the investigation of field level, the micrometeorological conditions, the soil moisture content and the … More irrigation amount were measured within and outside the greenhouses at Daiei Town area, Tottori Prefecture, and at a sand dune field at Arid Land Research Center, Tottori University, It was analyzed how the radiation and heat balance and the evapotranspiration were changed by soil water moisture content and the growth conditioned of crops. Also, the micrometeorological conditions were measured in a paddy field, and the relation between Penman's potential evapotranspirations and evapotranspirations was investigated.The water movements was simulated with using the data measured in fields. Also, the development of simulation code for water movements was started. Furthermore, the potential evapotranspiration by Penman's equation was calculated by using the AMeDAS meteorological data and the meteorological materials at the Meteorological Agency, and the distribution map of that was drawn. On the basis of the measurements and simulation results mentioned above, the reasons of the difference between the planning and the actual situation were examined, and the ideal method for the upland irrigation planning were investigated.A part of these results have already been published. More papers will be published in the future. Less

本研究的目的是调查田间和农场层面的旱田灌溉规划系统。为了实现这一目标，测量了灌溉原因的气象条件和蒸散量，并分析了两者之间差异的原因。调查了旱田灌溉区的设计需水量和实际需水量。农场层面的调查是利用 1993 年东伯灌溉项目地区测量的数据进行的。每个农场每小时和每天的用水量。通过对池塘进行分析，调查发现，在长、晴、旱天，用水量增加，每小时用水高峰与设计需水量基本相同，而且水库的峰值流量也相同。农场池塘的时间是早上和晚上。作为田间调查，在鸟取县大荣町地区的温室内外和沙丘上测量了微气象条件、土壤含水量和灌溉量。干旱之地的田野鸟取大学研究中心，分析了土壤水分含量和作物生长条件对辐射热平衡和蒸散量的影响，并测量了稻田的微气象条件，以及彭曼潜力之间的关系。研究了蒸散量和蒸散量。利用现场测量的数据模拟了水流运动，并开始了水流运动模拟代码的开发。此外，还研究了潜在蒸散量。利用AMeDAS气象资料和气象局气象资料计算了彭曼方程，并根据上述实测和模拟结果，绘制了彭曼方程的分布图，分析了规划与实际存在差异的原因。考察了实际情况，探讨了旱田灌溉规划的理想方法。部分成果已经发表。更多论文将在未来发表。
