Study on the Goal and Plan to achieve it for Consolidation of Rural Environment as the Secondary Nature

在前现代时期，农村人类活动与农村环境作为次要自然存在共生关系。虽然这种共生关系随着现代人类活动的现代化而迅速被打破，但本研究通过对当时正在进行水稻种植活动的老年农民的访谈调查，提取了这种共生关系的主结构，并通过对当时正在进行水稻种植活动的老年农民的访谈调查，重新构建了1950年前与区域环境密切共生的人类活动样本--赤木县的水稻种植活动。另一方面，通过实地调查和与赤木农研推广中心研究人员的座谈，记录了目前与区域环境已经失去共生关系的水稻种植活动。然后，从后石油时代可持续工程的合理条件的角度对前现代和现代水稻种植活动的各个要素进行了评价，并将被评价为正的元素的守恒和被评价为负的元素的交替的组合理解为真正的后现代时代的部分人类活动。结果表明，只有在基于生物质资源的新能源工程的假设下，才有可能重建这种足够的人类活动。

There was the symbiosis between the rural human activities and rural environment as secondary nature in pre-modern time. Although such symbiosis was broken rapidly according to the modernization in human activities now, Principal structure of the symbiosis was extracted from hearing data from old farmers about rice growing activities in Tochigi prefecture in pre-modern time in this research.Thus, rice growing activities in Tochigi prefecture before 1950 as a sample of the human activities which had tight symbiosis with regional environment was re-built through interview survey to old farmers who ware actually doing rice growing activities at that time. Other hand, present rice growing activities which is losing symbiosis with regional environment already was recorded by mean of both of field survey and discussion with researchers of Tochigi agricultural research extension center. Then, each element of rice growing activities of both of pre-modern time and modern time ware evaluated from view points of reasonable conditions of sustainable engineering in post petrol era, and the combination of conservation of the elements which evaluated as plus, and alternation of the elements which evaluated as minus was understood as adequate rice growing activities as a partial human activities at real post modern era.As the results, it was understood that the re-building of such adequate human activities are only possible on the assumption of some new energy engineering based on biomass resources.
