Gis and its support for regional farming

研究结果表明：(1)利用地理信息系统（GIS）对I区T村的农田管理进行分析，可以直观地处理个体农户的农田积累和土地利用模式信息，提高了分析的质量。(2)将人和地图转换为数字信息，需要两类地图信息。人（农民）信息是土地的登记信息，对应于1到2500比例尺的数字地理地图作为底图。土地信息是土地的登记信息对应于1到2500以上比例尺的数字地理地图作为底图。需要新的发明来重叠两张不同缩小比例尺的地图。(3)山区直接支付从2000年开始实施。在本研究中，我们在ArcView上开发了一个系统来计算该项目下的农田直接支付，并进行了各种模拟实验。(4)如果对不同的土地利用方式和不同的梯度存在多个单位价格，则不同的农田束导致不同的总支付。我们通过上述系统来调查这个问题。选择不同的测量单位会产生相同的结果。

The findings of this research are as follows :(1) A close look at the farm management analysis at I district, T village in which we adapted geographic information system (GIS) to grasp the spatial pattern of farmlands reveals that the adaptation of GIS improves the analysis, since we can visually treat information about the accumulation and land use patterns of individual farmer's farmlands.(2) In order to transform person and land map into digital information, two types of map information are needed. The person's (farmer's) information is the registry information of land which corresponds to a digital geographical map on a scale of 1 to 2,500 as a base map. The land information is the registry information of land corresponds to a digital geographic map on a scale of 1 to over 2,500 as a base map. New invention for overlapping the two maps with different reduced scales is required.(3) The direct payment in mountainous regions has started since 2000. In this research, we develop a system on ArcView to calculate direct payment to a farmland under this project and perform various simulation experiments.(4) If there are several unit prices to different land uses and different gradients, different bundles of farmland result in different total payments. We investigate the issue by the above-mentioned system. Same thing emerges as a result of a different choice of measurement unit.
