Research on the Method of Land Use Regulation in Agricultural Land Improvement Projects

在土地改良法基础上实施的土地改良工程是为了改善农村地区的农业生产力和生活环境。以前这个项目被限制在农业用地促进区内。因此，在1972年和1984年两次修改了《农业振兴法》，使白色地带成为可能。因此。这使得蓝区和白区土地利用的调控成为可能。但土地整理工程在实践中有时显得过于超前。有时仍在使用旧方法。因此，本研究试图收集项目的例子，并澄清使用了什么方法，如何执行，原因是什么等等。以农区和居住区的土地基础设施整理工程为例进行了分析。以农用地整理工程为例，总结了12个实例。这十二种又可分为三种类型。六是通过置换地块提取非农业用地，二是考虑城市化的整合。并列举了4个采用相同方法制造大型水田的实例。此外，还收集了两个聚落重组案例。对于每一个例子，成员们都试图澄清上述各点。互相讨论。这些程序和结果都写在报告里。

Land improvement project based on the land improvement act is in execution ot improve agricultural productivity and living circumstances in rural area. Formerly this project was restricted within agricultural land promotion district. so the act was revised twice for making possible to include white zone in agricultural promotion in 1972 and 1984. As a result. it becomes possible to regulate land use in blue zone and that in white zone.But land consolidation project in practice sometimes becomes too far ahead of act. and sometimes remains in using old method. so this research tried to gather mxamples of project and to clarify what method was used and how executed and what is the reason etc. of every project.Four examples are collected on land infrastructure consolidation project concerning to agricultural district and residential district. Twelve examples are gathered on agricultural land consolidation project. These twelve are sub-categorized into three types. six was extraction of non-agricultural land through disposition of substitute lots, two are consolidation considering urbanization. and four are example of making large-sized paddy field using same method. Moreover two examples of reorganization of settlement were collected.On every examples, members tried to clarify on the points noted above. and discussed each other. These procedures and result are written in the report.
