摘要

研究证明了一种新型苔藓（由日本蕨（Racomitrium japonicum）合成的 Parkortanso 1 号，Dozy 和 Molk）在城市地区捕获二氧化碳的可行性。研究了光照强度（500、1000 和 1500 µmol/m2.s）、环境温度（10 °C、25 °C 和 35 °C）、年龄（1 岁和 3 岁）和叶片颜色（鲜绿和深绿）对相关苔藓去除二氧化碳的影响。结果表明，光照强度越强，目标苔藓的二氧化碳去除率越高。这种苔藓在 25 ℃ 时二氧化碳捕获能力最强，而当环境温度为 10 ℃ 和 35 ℃ 时，二氧化碳捕获能力下降。研究发现，3 年生的翠绿苔藓比 1 年生的翠绿苔藓具有更高的二氧化碳捕集能力。同样，在相关苔藓中，翠绿苔藓的二氧化碳吸收能力最强。翠绿苔藓的最高二氧化碳净排放量为 - 1.94 ± 0.72 kgCO2/m2.年，与其他苔藓和植物物种相当。因此，在二氧化碳捕获方面，建议将翠绿和古老的 Parkortanso 1 号苔藓用于绿色屋顶。

CO2 removal characteristics of a novel type of moss and its potential for urban green roof applications

The feasibility of a novel type of moss (Parkortanso No. 1 synthesized from Racomitrium japonicum, Dozy and Molk) to capture CO₂ in urban areas was demonstrated. The effects of light intensity (500, 1000, and 1500 µmol/m².s), ambient temperature (10 °C, 25 °C, and 35 °C), age (1-year-old and 3 years old), and leaf color (bright and dark green) on the CO₂ removal caused by the moss concerned were investigated. It was determined that stronger light intensity resulted in higher CO₂ removal by the target moss. The moss showed the best CO₂ capture at 25 °C, while the CO₂-capturing capacities declined when the ambient temperatures were 10 °C and 35 °C. Three years old bright green moss was found to have higher CO₂-capturing capacity than 1 year old. Similarly, bright green moss exhibited the best CO₂ uptake out of the mosses concerned. The highest net CO₂ emission of the moss was − 1.94 ± 0.72 kgCO₂/m².year, which was comparable to other moss and plant species. Consequently, the bright green and old Parkortanso No. 1 moss are recommended for a green roof application in terms of CO₂ capture.
