ESTABLISHMENT OF MONITORING METHOD SUITABLE FOR THE NATURE RESTORATION

本研究旨在建立简单而频繁的社区监测计划，具有较强的科学基础，强调一致的数据收集和记录，适用于新知湖和中泉湖的自然恢复项目。在2006年的最后一次研究期间，调查人员在爱慕大学举行的日本湖泊学会年会上报告了他们的研究结果，并讨论了改进以社区为基础的监测方案。专题演讲如下：(1)会议开幕词，(2)岛根县新知湖和大桥河沿岸地区的恢复与环境研究；(3)修复芦苇带鱼类群落结构的监测技术；(4)通过观测中水湖底层沉积物监测底层状况；(5)新生湖和中泉湖的自然恢复--现状及其附着藻类的监测--定居过程；(6)环境水中硝酸盐的现场简单测定；(7)对日本新知湖沿海泻湖边缘带的碳动态进行监测。

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.
