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

前现代时期，农村人类活动与作为次要性质的农村环境存在共生关系。虽然随着人类活动的现代化，这种共生关系被迅速打破，但本研究从前现代枥木县老农民关于水稻种植活动的听力资料中提取了共生关系的主要结构。因此，通过对当时实际从事水稻种植活动的老农民的访谈调查，重建了1950年以前枥木县的水稻种植活动作为与区域环境密切共生的人类活动样本。另一方面，通过实地调查和与枥木农业研究推广中心研究人员的讨论，记录了目前水稻种植活动已经与区域环境失去共生关系。然后，从后石油时代可持续工程的合理条件出发，对前现代和现代水稻种植活动的每个要素进行评价，并将评价为正的要素的保护与评价为负的要素的交替相结合，理解为真正的后现代时代，充分的水稻种植活动是人类活动的一部分。因此，人们了解到，只有在某些基于生物质资源的新能源工程的假设下，才能重建这种适当的人类活动。

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.
