摘要
农地碳排放研究对于区域农业可持续发展具有重要意义。笔者利用1996—2013年贵州省化肥、农药、农膜、农用柴油、翻耕、灌溉六大类碳源的相关数据,对贵州省18年间农地利用碳排放进行测算,并采用kaya恒等式对农地利用碳排放的影响因素进行分析。研究表明:(1)贵州省农地利用碳排放总量和碳排放强度均呈现持续上升的态势;(2)贵州省农地利用碳排放增速呈现波动的状态,且波动幅度较大;(3)化肥是最主要的碳排放源,其次为农膜和农用柴油;(4)生产效率因素、产业结构因素对贵州省农地利用碳排放具有抑制作用,经济水平、劳动力规模对农地利用碳排放具有促进作用。最后,本文对贵州省农地利用碳排放提出对策建议。
Farmland carbon emission study on regional sustainable agricultural development is important. Theauthors used the data of chemical fertilizers, pesticides, agricultural films, agricultural diesel oil, plowing andirrigation from 1996 to 2013, calculated farmland carbon emission in Guizhou, and analyzed influencingfactors of farmland carbon emission by kaya identical relation. The results showed that：（1） the total amount andintensity of farmland carbon emission continuously increased in Guizhou;（2） the growth rate of farmlandcarbon emission showed a sign of fluctuation, and the fluctuation range was big;（3） chemical fertilizer was themain source of carbon emission, then were agricultural films and agricultural diesel oil;（4） productionefficiency and industrial structure had inhibiting effect on farmland carbon emission, and economic level andlabor force scale had promoting effect on farmland carbon emission. Finally, the authors put forward somesuggestions on farmland carbon emission in Guizhou Province.
