ESTABLISHMENT OF MONITORING METHOD SUITABLE FOR THE NATURE RESTORATION

本研究旨在建立一个简单、频繁的社区监测项目，该项目具有较强的科学基础，重点是数据的一致收集和记录，适合于真嗣湖和中海湖的自然恢复项目。在2006年研究的最后阶段，研究者在爱媛大学举行的日本湖泊学会年会上报告了他们的研究结果，并讨论了如何改进社区监测计划。介绍情况如下：(1)会议开场白，(2)岛根县新司湖和大桥河沿岸地区的恢复与环境研究，(3)恢复芦苇带鱼类群落结构监测技术，(4)中海湖底沉积物观测监测，(5)新司湖和中海湖自然恢复现状和附着藻类定殖过程监测，(6)环境水体中硝酸盐的现场简单测定；(7)日本真次湖滨海泻湖边缘带碳动态监测。

This study aimed at establishing the simple and frequent community-based monitoring program, having strong scientific underpinning with an emphasis on consistent data collection and recording, suitable for the nature restoration project in Lakes Shinji and Nakaumi. In the final study period of 2006, investigators reported their study results at the annual meeting of the Limnological Society of Japan, held at Ehime University, and discussions were made to improve the community-based monitoring program. Presentations were as follows ; (1) Opening remarks of the meeting, (2) Restoration and environmental research at coastal areas of Lake Shinji and Ohashi River, Shimane Prefecture, (3) Monitoring techniques of fish assemblage structures in a restored reed belt, (4) Monitoring of bottom conditions with the observation of bottom sediment in Lake Nakaumi, (5) Nature restoration of Lakes Shinji and Nakaumi-present conditions and monitoring-colonization process of attached algae, (6) On-site simple determination of nitrate in environmental water, and (7) Monitoring of carbon dynamics in the fringing zone of coastal lagoon, Lake Shinji, Japan.
