摘要
明确脱贫山区农户生计转型的低碳效应对实现乡村绿色发展、建设低碳乡村至关重要。基于陇南山区农户的入户调查数据,利用碳排放清单法分析了2014—2019年农户的生计转型路径及其低碳效应。结果表明:(1)陇南山区农户的生计策略分为传统农业主导型、经济作物主导型、务工主导型、经商主导型和综合型;2014—2019年有26.97%的农户生计策略发生了转型,最主要的转型方式是由综合型转向务工主导型;(2)因人均生活碳排放增加量高于人均生产碳排放减少量,陇南山区农户的人均家庭碳排放呈增加趋势;(3)农户生计转型路径中,由经济作物主导型转向传统农业主导型的人均家庭碳排放降幅最大,为41.45%,综合型转向传统农业主导型的增幅最大,达208.86%。
Background,aim,and scope Clarifying the low-carbon effect of the livelihood transition of farm households in poverty-stricken mountainous areas is crucial to realising the green transformation of villages and building low-carbon villages in China.However,most previous studies have focused on carbon emissions from households at the national or regional level.Few studies have examined the impact of changes in household livelihood strategies on carbon emissions.This study analysed the path of farmers’livelihood transformations and carbon emissions from 2014 to 2019,to clarify the impact of the transformations on carbon emissions.The data from poverty-stricken mountainous areas could provide a reference for rural low-carbon initiatives.Materials and methods Survey data on farmers’livelihood capital and main livelihood activities in the Longnan mountainous area from 2014 to 2019 enabled classification of the livelihood strategies.Using the Intergovernmental Panel on Climate Change carbon emission inventory method,the carbon emissions generated by the energy consumption associated with production and living materials of various farmers were calculated and the influence of livelihood transformations of farmers on household carbon emissions was analysed.Results(1)The livelihood strategies of farmers could be classified as traditional agriculture-,cash crop-,workers oriented-,business oriented-,and comprehensive-strategies because of their different income structures.(2)From 2014 to 2019,73.03%of the livelihood strategies of farmers remained unchanged.Among the farmers whose livelihood strategies changed,the proportion who changed from comprehensive to work-oriented was the highest(10.67%).(3)The per capita household carbon emissions of the studied farmers has increased because the increases in per capita living carbon emissions exceed the decreased production of carbon emissions.(4)Among the farmers whose livelihood strategies changed,10.76%of farmers’per capita carbon emissions declined.The decline from cash crop-
