项目摘要

It is the basic producing process in the tidal flat region where an inclusive finding had been extremely limited up to now though it is assumed most that the animal for each unit area production is a high place on the earth in this research according to various bottlenecks in the research. It was executed to assume a detailed, long-term surveillance study to be a base about Dynamics of the food web following it, to advance the quantification of various sources about Ca, and to execute construction of the ecosystem model in a necessity and an indispensable tidal flat region to the environmental protection in the future at the same time planning. It is impossible to construct a general modeling of the tidal flat group scattered in an environmental place where which it is long and slender and the temperature environment etc. are greatly different only with the observation example in the tidal flat in one place in the south north like our country. Then, our research team selected a typical … More tidal flat in three places from Hokkaido to Kyushu, obtained this quality and the same kind of observation and the experiment result in each place, aimed at the added role in the living thing of parents element movement of the benthos with a scarce finding so far, and it aimed to construct an inclusive ecosystem model who included it from the primary manufacturing to higher-order production that became the first case in quantification and our country. Basic production of the bottom life diatom was able to be estimated accurately by the research executed in the mouth of a river tidal flat in Takamatsu. Moreover, it was clarified that the level was a value that exceeded basic production in seawater the Inland Sea. In addition, the relation between a benthic animal and an environmental factor was understood in detail. As a result, the amount of the living thing and the composition influenced the living thing by an environmental factor, and it was clarified that the living thing oneself was regenerating the environment oppositely. Finally, it succeeded in making an inclusive ecosystem model in the tidal flat region. Less

这是滩涂地区的基本生产过程，迄今为止，尽管根据研究中的各种瓶颈，本研究大多假设单位面积生产的动物在地球上处于高位，但包容性的发现非常有限。开展详细的、长期的监测研究，作为今后食物网动态的基础，推进各种Ca源的定量化，并在规划的同时，在未来环境保护的必要性和不可缺少的滩涂地区进行生态系统模型的构建。仅以我国南北一处潮滩的观测为例，不可能对分布在狭长、温度环境等差异较大的环境场所的潮滩群建立一个通用的模型。然后，我们的研究团队选择了一个典型的 ...更多信息从北海道到九州的三个地方的潮滩，在各个地方获得了这种性质和相同的观察和实验结果，针对底栖生物的亲元运动在生物中的附加作用迄今为止发现很少，旨在构建一个从初级制造业到高级制造业的包容性生态系统模式，订单生产成为我国量化的第一例。通过在高松市河口潮滩进行的研究，能够准确地估计底栖硅藻的基本生产量。此外，有人澄清说，这一水平是一个超过内海海水基本生产量的数值。此外，还详细了解了底栖动物与环境因素之间的关系。结果，生物的数量和组成通过环境因素影响生物，并且明确了生物本身正在相反地再生环境。最后，成功地建立了一个潮滩地区的包容性生态系统模型。少
