项目摘要

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.

经济分析小组分析了有关环境社区业务的开创性项目的两个示例：福库卡报纸回收的业务模型和关于秋田食用油回收的商业模式。前者是一个实验，用于构建一个社区系统以进行共存，后者是一个试验，用于根据风险公司的利益在本地建造能量循环，而该公司在法律上比公共企业的限制少于公共企业，分析了通过使用统计数据和远程感知技术的Suwa-Tenryu地区开发的当地社区的开发（Landssatiquess）（LandSatsatstm（LandSatsats）（Landsatsats）（LandSatsattm）。 30年前建造的“金星线”的收费公路导致旅游业的发展，总收入的增加，草地破坏以及随着游客的增加而增加了垃圾和排泄物。除了采取行政措施外，NPO和公民的合作对于那些过度解决问题的人都很重要。自然调查小组继续对Tenryu河分支中的物质循环进行分析，研究了沿河主要通道的硝酸盐污染，并对河口沿海沙滩的大小分布进行了调查。建立了对河水中硅酸盐的新定量测量。分析了从Suwa湖收集的沉积物核心的光合色素和藻类组成。还对TBT分析了整个湖的表面沉积物。 Chironomid的新兴时间受到WARR温度的极大影响，近年来，苏瓦湖的数量显示出趋势的下降。工程组分析了苯甲醛在同烷基烷基上的吸附特性，通过使用木芯片，对有毒物质进行了不透明的纯化系统，并通过使用木质芯片开发了通过Nitrate of Nitrate of Nitrate污染的模拟模型。
