摘要:
以4种轻型屋顶绿化草本植物为研究对象，采用CIRAS-2型便携式光合仪测定不同光照强度下4种植物的瞬时CO2吸收量，得到单个植株和单位面积植物的瞬时固碳量，计算轻型屋顶绿化后的固碳总量及产生的经济效益。结果表明：槭叶兔儿风的单株瞬时CO2吸收量（固碳量）最高为35.42×10-6 g?s-1，其次是大吴风草为20.91×10-6 g?s-1，朝鲜白头翁为3.86×10-6 g?s-1，白花地丁的固碳量最少为3.68×10-6 g?s-1。徐州市W小区进行轻型屋顶绿化后一天的固碳量总计为251.28 kg，一天可以产生的经济效益为250.27元，每年产生的经济效益为9.13万元。
Abstract:
The instantaneous CO2 absorption of four herbs in light roof greening under different light intensities was determined by CIRAS-2 portable photosynthesis system,and then instantaneous carbon sequestration of single plant and plant per unit area were taken,in the end,the total amount of carbon fixation and the economic benefits were calculated.The results showed that the highest carbon fixation of Ainsliaea acerifolia was 35.42×10-6 g?s-1,the second was Farfugium japonicum 20.91×10-6 g?s-1,and then Pulsatilla koreana was 3.86×10-6 g?s-1,the minimum amount of carbon fixation was 3.68×10-6 g?s-1 by Viola patrini.After light roof greening,the day′s total carbon sequestration was 251.28 kg in W district of Xuzhou,economic benefits of 250.27 RMB were produced in one day,the annual economic benefits were about 91 300 RMB.
