Research on the supporting system to form regional consensus for rural land-use planning

由于聚落区不是通过土地评价确定的，而是从土地使用观念的角度“规划”确定的，虽然这在土地所有者之间造成了很大的利益矛盾，但由于土地所有者内部难以形成区域共识，因此很难制定包括聚落区部分划分为耕地在内的最优农村土地利用规划。因此，在这个过程中，需要提供许多备选方案供土地所有者讨论，以达成共识，这需要耗费大量的时间。如果将每个土地所有者和每个地块的所有属性（条件）作为数据库记录在计算机中，则可以在需要时在CRT上显示土地所有者意见和规划者意见的交叉结果，这有助于快速达成共识。本研究的主要目的是明确该支持系统的条件，并开发其计算机软件。选择枥木县的Tonara和Kamisinoi两个乡村作为案例研究区域。开发了(1)包含地块号的土地拥有状况和(2)包含耕作和家庭状况的两个业主档案，(3)包含地块号的土地登记图和(4)包含每个地块的土地状况的两个地块档案，以及一些交叉分析和CRT显示软件。最重要的是让土地所有者和规划者进行讨论，提出他们的意见和备选方案。并对开发的软件进行了改进，以供实际应用。主要研究结果发表在《农村规划学会学报》上。

It is not easy to establish optimum rural land-use plan including partial zoning of settlement area to farm land due to the difficulty in forming regional consensus within land owners, since the settlement zones are not determined by land evaluations but on "are planned" from the view point of land-use concept although it causes much contradiction of intersts among the land owners. So, that many alternative plans should be offered for land owners' discussion in the process to achieve the consensus, and this consumes a lot of time. If all attributes (conditions) of each land owner and each land lot are recorded as data-bases in the computer, cross results of land owners' opinion and planners' opinion can be shown on CRT when required, as it is useful to achieve consensus rapidly.The main aim of this research is to make clear the conditions of such supporting system and to develop its software for computer. Two rural hamlets of Tonara and Kamisinoi in Tochigi prefecture are chosen as the case study areas. Two owners' files of (1) land owning condition with land lot number and (2) farming and family conditions, two land-lots files of (3) land registration map with lot number, and (4) land conditions of each lot, and some cross analysis and CRT presentation software are developed. Above all are the proposal for discussion between land owners and planners to present theiropinion and alternatives. Also the developed softwares are improved for practical use. Principle results of research are presented in Journal of Rural Planning Association.
