项目摘要

In this study, the possibility of recycling facilities for waste wood in Saitama Prefecture is evaluated. As a result the CO_2 reduction potential is 720kt-CO_2 a year. Next, for the forest in Saitama Prefecture its functions of the flood control, water resource stock, and carbon dioxide adsorption are evaluated as 43 billion yen, 36.2 billion yen, and 9.6 billion yen respectively. In addition the GIS database constructed in this study is used for evaluation of the environmental efficiency in scenarios of introducing the water treatment technology system in Kumamoto prefecture. As a result, in the case of introducing sewage system to the area that population density is 350 (person/km2) or more and a septic tank to other areas, CO_2 emissions are smallest, 472kt-CO_2 and 17.9t-CO_2/t-BOD.

本研究对琦玉县废弃木材回收利用设施的可行性进行了评价。结果表明，该地区每年的CO_2减排潜力为720 kt-CO_2。其次，对琦玉县的森林的防洪功能、水资源蓄积功能、二氧化碳吸附功能分别进行了评价，分别为430亿日元、362亿日元、96亿日元。此外，本研究所建立的地理信息系统数据库，用于评估环境效率的情况下，引进的水处理技术系统在熊本县。结果表明，在人口密度大于等于350人/km ~ 2的地区设置污水处理系统，在其他地区设置化粪池的情况下，CO_2排放量最小，分别为472 kt-CO_2和17. 9 t-CO_2/t-BOD。
