1. Eight districts where the evaluation data for an agricultural water use condition could be obtained were selected as ones to be analyzed and six districts were selected as reservoirs irrigation areas from Okayama Prefecture, Hiroshima Prefecture and Ehime Prefecture by two while. Two districts were respectively selected as rivers irrigation areas from Hiroshima Prefecture and Okayama Prefecture one at a time.2. With respect to the evaluation items relating to an irrigation requirement condition wherein a unit of evaluation is set to a command area, evaluation standards and the subject of evaluation are unclear and the subjective element of a valuer participates largely and objective evaluation is difficult.3. With respect to the evaluation items of an irrigation canal condition evaluated in a parcel unit, the presence of irrigation canals could be objectively cleared and, in addition, the structure of facilities could be also grasped and, from this, rational items to be evaluated we … More re cleared. These evaluation items are common to both districts of reservoirs irrigation and rivers irrigation.4. Lands having no water rights such as wasteland, miscellaneous land, upland field can be dealed with on the basis of land evaluation in a substitute lot plan if the presence of water rights can be added to the evaluation items.5. A command area is affected by farm land consolidation and reorganized. Therefore, the balancing of agricultural water use condition becomes necessary apart from the balancing of exchange lots. In farm land consolidation, a water control organization formed at every command areas are unified and not unified according to circumstances. In both cases, the evaluation items of the irrigation canal condition is effective. The concept of the balancing of agricultural water use condition should be adapted only when the water control organizations are unified and the evaluation of the irrigation requirement condition should be dealed with therein. In the present condition, it is unreasonable to deal with the balancing of agricultural water use condition according to the balancing of exchange lots based on the land evaluation in the substitute lot plan, because the water control organization becomes the person concerned and the objective area of the substitute lot plan does not coincide with a command area.

1. 选取了8个能够获得农业用水条件评价数据的地区作为分析区，并从冈山县、广岛市和爱元县中选取了6个地区作为水库灌区。分别从广岛市和冈山县选取两个区作为河流灌溉区。（二）对将评价单位设置在指挥区内的灌溉需求条件评价项目，评价标准和评价主体不明确，评价人员主观因素参与较多，客观评价困难。通过对地块单元内的灌渠状况评价项目进行评价，可以客观地明确灌渠的存在，并掌握设施的结构，从而明确合理的评价项目。这些评价项目在水库灌区和河流灌区均具有普遍性。4 .荒地、杂地、旱地等无水权的土地，如果可以在评估项目中增加有水权的，可以在替代地块规划的土地评估基础上处理。某指挥区受耕地整理重组影响。因此，除了交换地块的平衡外，农业用水条件的平衡就显得十分必要。在农地整理中，各指挥区组建的治水组织根据情况有统一的，也有不统一的。在这两种情况下，灌渠状况的评价项目都是有效的。农业用水条件平衡的概念只有在统一的治水组织下才能适用，只有在统一的治水组织下才能进行灌溉需水量条件的评价。在目前的条件下，替代地块规划中以土地评价为基础，根据交换地块的平衡来处理农业用水条件的平衡是不合理的，因为治水组织成为相关主体，替代地块规划的目标面积与指挥面积不一致。少
