【正文】 1 基于 API 方法的成都市大氣污染評(píng)價(jià) 摘要： 采用空氣污染指數(shù) API 法對(duì)成都市 20xx 年大氣環(huán)境質(zhì)量進(jìn)行了評(píng)價(jià)。結(jié)果表明： 20xx 年成都市空氣質(zhì)量達(dá)到國(guó)家二級(jí)標(biāo)準(zhǔn) 的達(dá)標(biāo)率為 %。影響成都市空氣質(zhì)量的主要污染物為可吸入顆粒物 ,主要污染時(shí)間為 12 月。影響因素為氣象和人為活動(dòng)。建議采取加快城市綠化和固化建設(shè) ,優(yōu)化產(chǎn)業(yè)結(jié)構(gòu)，大力發(fā)展和推廣使用清潔能源等污染防治對(duì)策 。 關(guān)鍵詞 ： API；成都；質(zhì)量評(píng)價(jià) Assessment of Air Pollution in Chengdu Based on API Wei hanli （ Environment Engineering, Urban and Rural Development College, Sichuan Agricultural University, 611830) Tutor: Yang keyan(Associate professor ) (Department of Environmental Science and Engineering, Urban and Rural Development College, Sichuan Agricultural University, 611830) Abstract: This thesis assesses the atmosphere environmental quality with the air pollution index method,take example for air quality of Chengdu in 20xx. The results show: Chengdu in 20xx meet the Grade II national standards for air quality rate of %. The particulate is the key pollutant affecting the air quality in Chengdu. And the main affect periods are January,March and December. The affect factors are weather and factitious activities. Efforts should be made to strengthen urban afforesting and greening, optimize the urban industrial structure, and developing the use of cleaner highquality energy.
