According to the environmental background and air quality related data trends over the years, the elimination of overseas pollution, Penghu County air pollution mainly comes from the tourist season tourists population and vehicles, ships, economic development has a relative contribution to air pollution.
Observe the change trend of AQI level in Magong station in recent four years, and find out AQI > 50 good ratio increase,100-150 AQI the ratio was reduced from the 7.7% to the year 5.8%, and at the end of the year PM2.5 average annual value of manually measured stations (14.6µg/m3) and 98% high Values (32µg/m3) all meet air quality standards and are the lowest in the calendar year.
Through the annual "Regional Air Quality model simulation Analysis" plan to understand the county affected by the impact of foreign pollution, simulation results show that the county's pointer pollutants from overseas migration ( including background + sea salt ) average impact: daily maximum 8hours O3 concentration affected by 95%;PM per concentration affected by 92 %;PM2.5 concentration is affected by 84%. in response to the Environmental Protection Department's pre-release of the TEDS10.0 version, reference to its fugitive source PM2.5 /pm conversion coefficient ratio, to revise the county base year emissions. After the revision of the county farmland wind erosion and coastal wind erosion PM emissions originally accounted for 72.4%, updated after the 60.5%,PM2.5 originally accounted for 64.6%, updated after the 19%, the catering industry for the county PM2.5 The main source of contributions.
Penghu county year 107 results of the implementation of the control strategies for the year: Coastal afforestation has been completed 2,230 hectares since 81~107 , joint County capitals of the relevant Bureau resources to jointly promote environmental green beautification, reduce exposed wind erosion dust emissions, and media 4 air quality purification areas for private enterprises to be recognized, Jianshan power plant in the the year of the company, the section and the region won the excellent foster Enterprise Group, Won the excellent recognition unit to contribute to the excellence Award; two- trip locomotive from the year to the year of the period of the old 7,838 vehicles, the cumulative proportion of the old ratio up to 70%; Two period of old large diesel vehicles a total of 160 , the removal of the results of the country's 1 , the proportion of motor vehicles to 4.5%, the largest share of the country, the current year through the relevant promotional programmes, so that the purchase quantity is more 3 times the growth of the year, the carbon roasting industry has been repeatedly identified by the anti-production equipment to rent the purchase of purchasing, has completed the installation and operation of a set of electrostatic dust collector machine, construction projects in the hot zone of active inspection and advocacy, To reduce the number of cases of 60%, the overall satisfaction of the population to 80%; Jianshan power plant SCR control efficiency of 76.3%; boiler replacement to complete the improvementthrough the continuous construction of wind turbines and solar turbines, renewable energy generation has reached a total capacity of 10.4%.
