2、料分析秸稈焚燒對環(huán)境空氣質(zhì)量的影響。研究結(jié)果表明,秸稈焚燒主要分布在冬小麥生產(chǎn)區(qū),華北平原是秸稈焚燒集中區(qū)域,火點(diǎn)數(shù)占全國的86.9%;秸稈焚燒主要發(fā)生在6月上半月,火點(diǎn)數(shù)占全月的87.3%。相關(guān)分析表明,該市700、800km范圍緩沖區(qū)內(nèi)火點(diǎn)數(shù)變化趨勢與空氣污染指數(shù)有較好一致性,相關(guān)系數(shù)均達(dá)0.54,當(dāng)秸稈焚燒發(fā)生在不利于污染物擴(kuò)散的氣象條件下時,將導(dǎo)致空氣質(zhì)量明顯下降。關(guān)鍵詞:衛(wèi)星遙感;秸稈焚燒;火點(diǎn)分布;空氣質(zhì)量中圖分類號:X87;TP79文獻(xiàn)標(biāo)識碼:A文章編號:1673-4831(2009)01-003
