摘要：
Ozone pollution damages photosynthesis, reduces plant growth and biomass accumulation, and limits crop yields. Aerosol pollution influences plant photosynthesis through changes to the quantity and quality of radiation, meteorology and hydrology. The land ecosystems of China are estimated to provide a carbon sink, but it remains unclear whether air pollution acts to inhibit or promote carbon uptake. Here, we apply Earth system modelling and multiple observational datasets to understand (i) the individual and combined effects of ozone and haze pollution on plant productivity in China (ii) to attribute the air pollution vegetation impacts to economic source sectors including agriculture, road transportation and industry.
