中文摘要: 采用全球气候模式NorESM1-M产生的RCP2.6、RCP4.5、RCP6.0和RCP8.5气候变化情景数据和植物异戊二烯排放计算模型,模拟分析了未来气候变化对武夷山自然保护区毛竹(Phyllostachys pubescens)异戊二烯排放速率的影响.结果显示,气候变化下武夷山自然保护区气温上升,年降水量和辐射强度波动较大,呈增加或下降趋势.毛竹异戊二烯平均日排放速率在未来气候变化情景下比基准情景下高约30 $g·g~(-1)·d~(-1),在RCP8.5情景下比基准情景下高约48 $g·g~(-1)·d~(-1);毛竹异戊二烯日排放速率在未来气候变化情景与基准情景下的差异在1~ 90 d和301~ 365 d较小,在91~ 300 d差异较大;相比基准情景,未来气候变化情景下毛竹异戊二烯日排放速率在1~ 190 d(平均增加15%以上)和271~ 365 d(平均增加20%)增幅较大,在191~ 270 d增幅较小,在RCP8.5情景下增幅最大(平均增加17%).另外,毛竹异戊二烯年排放速率在未来气候变化情景下比基准情景下约高10000 $g·g~(-1)·a~(-1)以上,在RCP8.5情景下比基准情景下约高13%.研究表明,未来气候变化将使毛竹异戊二烯排放速率增加.
英文摘要: Based on the RCP2.6,RCP4.5,RCP6.0 and RCP8.5 climate change scenarios produced by global climate model of NorESM1-M and the model of isoprene emissions from plant,the effects of future climate change on isoprene emission rate from leaves of Phyllostachys pubescens were projected. The results show that the annual air temperature is increasing,and the annual precipitation and radiation intensity will fluctuate greatly,showing an increase or decrease trend in Wuyi natural reserve. Following climate change,the emission rate of isoprene from leaves of Phyllostachys pubescens is about 30 mug·g~(-1)·d~(-1) higher in the future climate change scenario than that in the baseline scenario,and which is 30 mug·g~(-1)·d~(-1) in the RCP 8.5 scenario; the difference of isoprene daily emission rate between in the future climate change scenarios and in baseline scenarios is lower in 1 ~ 90 days and 300 ~ 365 days than that in other days during whole years,and which is higher in 91 ~ 300 days than that in other days during whole years; compared to baseline scenarios,daily emission rate of isoprene from leaves of Phyllostachys pubescens increase higher at 1 ~ 190 days (above 15% on average) and 271 ~ 365 days (an average increase of 20%) than that in other days during whole years in future climate change scenarios,and which increase lower in 191~ 270 days than that in other days during whole years,and which increase the highest (an average increase of 17%) in the RCP8.5 scenario among different scenarios. In addition,the annual emission rate of isoprene from leaves of Phyllostachys pubescens is about 10000 $g·g~(-1)·a~(-1) higher in the future climate change scenario than that in the baseline scenario,and above 13% higher in the RCP8.5 scenario than that in the baseline scenario. The results show that future climate change will lead to an increase in the rate of isoprene emissions from leaves of Phyllostachys pubescens.
