【摘要】：以生命周期評價(jià)(LCA)為基礎(chǔ),選取農(nóng)業(yè)能耗狀況(化肥、農(nóng)藥、農(nóng)膜施用強(qiáng)度)、農(nóng)業(yè)生產(chǎn)低碳績效(碳生產(chǎn)力、財(cái)政支農(nóng)強(qiáng)度、農(nóng)業(yè)碳排放效率)等評價(jià)指標(biāo),運(yùn)用趨勢分析法、對比分析法等分析安徽省低碳農(nóng)業(yè)發(fā)展現(xiàn)狀,并對低碳農(nóng)業(yè)中化肥、農(nóng)藥、農(nóng)膜使用量等影響因素進(jìn)行回歸分析。結(jié)果表明,2000—2014年安徽省農(nóng)業(yè)生產(chǎn)中化肥、農(nóng)藥、農(nóng)膜等碳排放源的排放強(qiáng)度均呈現(xiàn)逐年下降趨勢,碳生產(chǎn)力逐年良性發(fā)展,農(nóng)業(yè)碳排放效率逐年提高,農(nóng)業(yè)碳排放總體呈正平衡狀態(tài)。各因素對農(nóng)業(yè)總產(chǎn)值的影響從大到小依次為化肥施用量、農(nóng)藥施用量、農(nóng)膜施用量、農(nóng)用柴油使用量,其各自用量每增加1%,農(nóng)業(yè)總產(chǎn)值就相應(yīng)地分別增加1.36%、1.14%、-0.70%、0.49%。
[Abstract]:Based on life cycle evaluation (LCA), agricultural energy consumption (chemical fertilizer, pesticide, agricultural film application intensity), low carbon performance of agricultural production (carbon productivity, financial support for agriculture) were selected. Agricultural carbon emission efficiency) and other evaluation indicators, using trend analysis, comparative analysis and other analysis of the development of low-carbon agriculture in Anhui Province, and low carbon agriculture fertilizer, pesticides. The results showed that the emission intensity of chemical fertilizer, pesticide, agricultural film and other carbon emission sources in agricultural production of Anhui Province from 2000 to 2014 showed a decreasing trend year by year. Carbon productivity has been developing well year by year, agricultural carbon emission efficiency has been improved year by year, and agricultural carbon emissions have a positive balance. The effects of various factors on agricultural output value from big to small are chemical fertilizer application and pesticide application. For each increase in the amount of agricultural film and diesel oil, the total agricultural output value increased by 1.36% and 1.14% -0.70%, respectively, and 0.49% of the total agricultural output value was increased.

【正文快照】： 低碳農(nóng)業(yè)是當(dāng)前應(yīng)對氣候惡化、生態(tài)危機(jī)時(shí)低碳經(jīng)濟(jì)背景下以低消耗、低污染、低排放、高效益、高碳匯為基礎(chǔ)的新型農(nóng)業(yè)發(fā)展形態(tài),是農(nóng)業(yè)可持續(xù)發(fā)展的升華。低碳農(nóng)業(yè)既有別于過度依賴化肥、農(nóng)藥等生產(chǎn)資料的化學(xué)農(nóng)業(yè),又有別于強(qiáng)調(diào)回歸自然、拒絕化學(xué)品的有機(jī)農(nóng)業(yè),也有別于適度使，
