Economical analysis group analyzed two examples of pioneering projects on environmental community business : business model on newspaper recycling in Fukuoka and business model on recycling of cooking oil in Akita. The former model is an experiment in constructing a community system for coexistence, and the latter one is a trial for constructing energy cycling in a local area in accordance with the benefit of venture companies, which are legally less restricted than public enterprises.Social system group analyzed the development of local communities in Suwa-Tenryu Area by using statistical data and remote sensing techniques (LANDSAT TM). The toll road of "Venus Line", which was constructed 30 years ago, caused development of tourism and increase in gross income, and destruction of grassland and increase in trash and excreta accompanying with the increase of tourists. In addition to the administrative measures, NPO and citizens' cooperation are important for those overuse problems.Natural survey group continued an analysis of material cycling in a branch of the Tenryu River, studied groundwater nitrate pollution along the main channel of the river, and conducted a survey on the size distribution of coastal sands at the mouth of the river. A new quantitative measurement of silicate in river water was established. Photosynthetic pigments and algae composition were analyzed for the sediment cores collected from Lake Suwa. TBT was also analyzed for surface sediment of the entire lake. Emerging time of a chironomid was greatly affected by waterr temperature, and their number showed a decreasing trend in recent years in Lake Suwa.Engineering group analyzed adsorption properties of benzaldehyde on allophane, improved purification systems for toxic substances by using wood chips, and developed a simulation model of groundwater pollution by nitrate.

经济分析组分析了福冈报纸回收商业模式和秋田食用油回收商业模式两个环境社区商业的开创性项目实例。前一种模式是构建共存的社区体系的实验，后一种模式是根据风险公司的利益在局部地区构建能源循环的实验，风险公司在法律上受到的限制比公共企业少。社会系统组利用统计数据和遥感技术（LANDSAT TM）对水和天流地区当地社区的发展进行了分析。30年前修建的“维纳斯线”收费公路，发展了旅游业，增加了总收入，但随着游客的增加，草原遭到破坏，垃圾和排泄物增多。对于过度使用的问题，除了行政措施外，NPO和公民的合作也很重要。自然调查组对天龙江某支流的物质循环进行了分析，对天龙江主河道的地下水硝酸盐污染进行了研究，并对天龙江入海口海岸砂的大小分布进行了调查。建立了一种新的测定河水中硅酸盐含量的定量方法。对苏瓦湖沉积物岩心的光合色素和藻类组成进行了分析。并对整个湖的表层沉积物进行了TBT分析。苏瓦湖摇尾虫的出现时间受水温影响较大，近年来摇尾虫的数量呈减少趋势。工程组分析苯甲醛对allophane的吸附特性，改进木屑对有毒物质的净化系统，建立硝酸盐污染地下水的模拟模型。
