Based on the emission inventory of air pollution sources in Wuhan in 2014,and information from Planning of Urban Air Quality Compliance in Wuhan (2013-2027),SO₂,NO_x,PM₁₀,and PM_2.5 emissions can be reduced by controlling the establishment of ‘two high’ industries,managing pollution sources,eliminating backward productivity,and controlling the motor vehicle population.An environmental effect simulation was conducted by applying the Nested Air Quality Prediction Modeling System (NAQPMS).The results indicated that if the Compliance Plan was implemented as intended,the SO₂,NO_x,PM₁₀,and PM_2.5 emissions in Wuhan in 2020 will decline by 22%-66%,6%-37%,14%-40%,and 17%-46%,respectively,as compared to 2014.Thus,air quality in Wuhan will improve.However,the annual concentrations of NO₂,PM₁₀,and PM_2.5 will still not comply with the Grade Ⅱ Ambient Air Quality Standard.
