With the global increase of tropospheric ozone ( O_3 ) and complex interactions between biogenic volatile organic compounds ( BVOCs) emissions and tropospheric O_3 concentrations,this review summarizes current research progress and future research prospects in terms of the effects of elevated O_3 on BVOCs emissions. The main progress included impacts of BVOCs categories,plant functional types,O_3 sensitivity of plants,the O_3 stress level on the response of BVOCs emissions to single O_3 stress,and the combined effects of elevated O_3 and temperature,carbon dioxide ( CO_2 ),drought,and nitrogen ( N) deposition. Results indicated that most published results reported no change in BVOCs emissions in response to increasing O_3 concentration. Specifically,decreasing effects of O_3 on BVOCs emissions were more obvious in studies on isoprene and deciduous species,whereas studies on monoterpenes and evergreen plant species showed more results with an increasing trend as well as acute O_3 exposure experiments. There was an increased tendency of monoterpene emissions to the combined effects of O_3 and temperature or N deposition. However,the combined effects of O_3 and CO_2 decreased isoprene emissions. Given that studies on the effects of O_3 on BVOCs emissions remain scarce,more complete experiments are needed that consider differences between short-term and long-term or individual-level and ecosystem-level. Furthermore,future research should strengthen the multi-factor interactive studies,particularly on O_3 and other global change components and biotic and abiotic stresses,to assess BVOCs emissions from terrestrial ecosystems in response to O_3 pollution both currently and in the future, which will provide valuable theoretical support to air pollution control.
