A Interdisciplinary Study about the Trace System of Vegetable by Geographic Information System

在本项目中，我们通过地理信息系统对蔬菜的痕量系统进行了研究，我们没有日常使用的蔬菜痕量系统，我们有一些试验的蔬菜痕量系统。在农林部有试行追踪制度，在禅宗有安全救济制度。我们详细研究了这些系统。分析了MAFF蔬菜试验微量系统和Zen no系统未能普及的原因。这些系统没有普及的原因是蔬菜生产和分销的复杂性和高成本，也就是说农民采用这些系统没有任何好处。根据对零售商的调查，零售商和消费者需要的不是每个农民的蔬菜生产信息，而是生产过程中的信息。根据JA的听证会调查，我们了解到每个农民的蔬菜生产信息并不可用，我们表明地理信息系统是有效的，当我们将每个农民的蔬菜生产信息不仅用于跟踪系统，而且用于蔬菜生产时。我们在日本山形冲山县的吉岛县制作了数字地图。我们已经完成的数字地图大约有1000公顷。但是我们不能把每一块地都完全与土地所有者对应起来。我们无法开发出完善的GIS模型，所以我们开发了GIS测试模型。

In this project, we have studied about the trace system of vegetable by geographic information systemWe do not have the trace system of vegetable, which we are able to use everyday, and we have some trial trace systems of vegetable. There are a trial trace system in the Ministry of Agriculture, Forestry and Fisheries and a safety relief system in Zen no.We examined these systems in detail. We analyzed reason why a trial trace system of vegetable in MAFF and Zen no system do not become popular. The reason why these system do not become popular is the complexity of the vegetable production and distribution and the high cost, that is to say there is no merit in farmers in adopting these systems. According to the hearing survey at retailers, retailer and consumer do not to need the information about vegetable production in each farmer but to need that in production grope. According to the hearing survey at JA, we knew that the information about vegetable production in each farmer is not available usefullyWe showed that the geographic information system is effective when we use the information about vegetable production in each farmer not only trace systems but also to vegetable production. We have made the digital map in Yoshisima arer in JA Yamagata Okitama. The digital map which we have finished is about 1000ha. But we could not correspond each field to land owner completely. We could not developed perfect GIS model, so we have developed GIS test model..
