项目摘要

Results from this research are outlined as follows.1. The historical review of developing process of the coastal area in the Inland Sea of Seto and modern subjects of this area: There are three stages in land and water resources development in this area. The historical trace of those stages remains in the modern utilization of land and water. Today it has already started to rearrange the utilization system.2. Rearrangement of the water use system: As economical activity in non-agriculture sector remarkably raises in the area today, it is necessary to rearrange the water use system and the canal system constructed in the past for agriculture. The national oriented irrigation project is undertaken to improve the system. As its results, it is clear by this investigation that the efficiency of water utilization decreases and the new water demand occurs by this rearrangement.3. The intensive use in sea water reclaimed land and the improvement of infra-structures for drainage: In the reclaim … More ed land for agricultural production in the past, the intensive land use, that is, urbanization or improvement for multi-purpose agricultural land use is progressed in the present. The runoff characteristics change and the safety level against flood damage remarkably goes down. It is clear that the regional drainage facilities for both of the rural and urban area, pump station and drainage canal, are used to be improved by the land improvement institution, and its purpose and technical contents are changing from the conventional agricultural drainage.4. The role of the land improvement institution and the future subject in the development of the area: It will become the most important problem to rearrange the land and water utilization system in this area. It is concluded that this arrangement should be undertaken mainly as the national oriented land improvement project. It is also pointed out that it is important to improve the behind mountainous area, which is a catchment area of rainfall in the upstream, at the same time of improvement for the coastal area. Less

这项研究的结果概述如下1。对Seto内陆海和该地区现代主题的沿海地区发展过程的历史回顾：该地区的土地和水资源开发中有三个阶段。这些阶段的历史痕迹仍然存在于土地和水的现代利用中。今天，它已经开始重新排列利用率系统2。用水系统的重排：随着当今该地区非农业部门的经济活动明显提高，有必要重新安排用水系统和过去建造的运河系统进行改革。实施了以国家为导向的灌溉项目来改善系统。由于其结果，这项投资可以清楚地表明，用水的效率降低了，而新的用水需求发生在此重排3中。3。在海水回收的土地上的大量用途和用于排水的基础设施的改善：在回收中……过去的农业生产土地更多的土地，即多功能农业土地利用的大量土地使用，即城市化或改善。径流特征发生了变化，针对洪水损害的安全水平明显下降。显然，粗糙和城市地区，泵站和排水管的区域排水设施用于土地改善机构的改进，其目的和技术内容正在从常规的农业排水管中发生变化。4。土地改善机构和未来主题在该地区的发展中的作用：重新排列该地区的土地和用水系统将成为最重要的问题。可以得出结论，该安排应主要作为面向国家的土地改善项目进行。还可以指出，改善山区背后的地区很重要，这是上游降雨的集水区，同时沿海地区改善。较少的
