ライフサイクル CO2評価に基づいた都市公園の整備計画に関する研究

抄録

To arrest global warming,it is also expected that the effect of carbon storage and sequestration of urban green spaces will be an important factor. On the other hand,the life cycle CO2 (hereafter, LCCO2) evaluation to reduce CO2 emissions is watched with interest by each sector. Because of this situation, the purpose of this study was to discuss the planning and design of urban Parks based on LCCO2. The study parks estimated in this study were selected 5 block parks in Sapporo City, Hokkaido. The results are follows: 1) It were possible to apply the LCCO2 evaluation method to all study parks. 2) In the study parks under the present conditions, the average amount of LCCO2 per area of 1 hectare of each sample was estimated about 58.4t-C/ha (range:45.9–78.6t-C/ha). 3) In the study park (3 types) changed basing on a landscape planning considered to reduce the amount of LCCO2, the average reduction rate of LCCO2 was estimated about 17.1–42.0%. 4) Therefore, we grasped to be important to discuss landscape planning considered to reduce the amount of LCCO2.
