基于投入视角的农业碳排放时序特征及因素分解研究--以西南岩溶山区重庆市为例
Research on temporal characteristics and factors of decomposition agricultural carbon emission based on input angle---Taking Southwest Karst Mountain area of Chongqing City for example
摘要
Abstract
Based on the chemical fertilizer,pesticide,agricultural film and other 6 major agricultural means of production as carbon source,carbon conversion coefficient method proposed by IPCC was used to measure agri-cultural carbon emissions of Chongqing in 1985—2012,at the same time,the factors decomposition of agricultural carbon emission was analyzed by LMDI model.The reslut showed that:(1)From the view of time series,the car-bon emissions of Chongqing agricultural in 1985—2012 showed the characteristics of “rise-steady-rise”;(2) from the view of carbon emissions structure,various types of Carbon source on agricultural Carbon emission showed great differences,the contribution of agricultural carbon emissions was fertilizer >agricultural irrigation >agricultural film >agricultural pesticides >agricultural machinery > tillage,fertilizer and agricultural irrigation accounted for 76.36% of total carbon emissions;(3)From the view of decomposition results,taking the year of 1985 as base period,agricultural production structure factors,efficiency factors and labor factors achieved a total carbon emissions of 3.06%,350.71% and 115.76%,while agricultural economic factors produced a total car-bon emissions of 620.91%.According to the characteristics of agricultural carbon emission,the advices of devel-oping new agricultural inputs and circular agriculture vigorously,accelerating the promotion of agricultural energy saving and emission reduction were proposed.关键词
