项目摘要

The actual condition of the paddy field ecosystem was investigated on vegetation, insect, fish in the relation with environmental structure of the paddy field region. And, rice cultivation modernization was investigated focusing to the transition of the technology, and obtained results ware stored into the personal computer memory in the form of tree structure. Each technical element was evaluated from both view points of the necessities in modern farming and impact on the paddy field environment. From this evaluation, the initial condition to consider the technology composition of sustainable rice cultivation was gasped bay mean of both of the deletion of technical elements which are not indispensable as modern technology and of the abandon to recover the elements of the paddy field ecosystem which are compensation of the modernization.Each pair of the technical elements and ecosystem elements was examined the capability of coexistence, and reasonable alternative form of modern paddy farming technology to realize such coexistence was introduced from newly developed "Hypothesis of sustainable condition of technology". But, this hypothesis is not perfect but has been remaining in under developing unfortunately.However, reformed harmony between modern rice farming and paddy eco-system was gasped by mean of structural integration of mostly fixed sustainable form of farming technologies. And also, remained stage of research will be continued depending on own laboratory resources.

调查了稻田生态系统植被、昆虫、鱼类的实际状况及其与稻田区环境结构的关系。并且，以技术的转变为中心对水稻种植现代化进行了研究，并将获得的结果以树形结构的形式存储到个人计算机存储器中。每个技术要素都从现代农业的必要性和对稻田环境的影响两个角度进行了评估。从本次评价来看，考虑可持续水稻种植技术构成的初始条件是，既删除了现代技术中非必要的技术要素，又放弃了恢复稻田生态系统的要素。考察了每一对技术要素和生态系统要素的共存能力，并从新发展的“技术可持续条件假说”中引入了实现这种共存的现代稻作技术的合理替代形式。但是，这一假设并不完美，不幸的是一直处于发展阶段。然而，现代稻作农业与稻田生态系统之间的和谐改革是通过大多数固定的可持续农业技术形式的结构整合而被打破的。并且，剩余阶段的研究将根据自己的实验室资源继续进行。
