【摘要】 选取镇江市2002年至2017年化肥、农药、地膜、农用柴油、农业翻耕、农业灌溉等碳排放碳源进行农业碳排放量的测算。研究测算结果发现:镇江市农业碳排放量整体呈先上升后下降趋势,农业碳排放强度处于稳定下降状态;化肥释放的碳排放量占比最大,农用柴油的碳排放量占比最小;从镇江市各地区占比来看,丹阳市和句容市占比最大,京口区和润州区占比最小。更多还原

【Abstract】 Six carbon carbon sources such as chemical fertilizers, pesticides, plastic film, agricultural diesel, agricultural tillage, and agricultural irrigation were selected from Zhenjiang for the calculation of agricultural carbon emissions from 2002 to 2017. According to the calculation results, the research found the followings: The overall carbon emission of Zhenjiang has increased first and then decreased, and the intensity of agricultural carbon emission is in a stable decline; The proportion of carbon emissions released by chemical fertilizers in Zhenjiang is the largest and agricultural diesel carbon emissions accounts for the smallest proportion. From the perspective of total proportion, Danyang and Jurong account for the largest proportion, and Jingkou and Runzhou account for the smallest proportion.更多还原
