Agricultural greenhouse gases emissions and influencing factors in China
摘要
Abstract
AbstractGreenhouse gases produced by the process of agricultural production plays large proportion of total amount of greenhouse gases emissions of worldwide production activities. Therefore, estimating agricultural greenhouse gases emissions, analyzing the influencing factors and discussing the achievement of agricultural energy conservation have important significance. Using the statistical data related to Chinese agricultural production in 1993−2011, the research estimated emissions of CH4, N2O and CO2generated by agricultural production in China and analyzed the influencing factors based on previous research results on emission factors in agricultural production of greenhouse gases emissions. The results showed that, CH4 emission from agriculture production in China was basically stable with small fluctuations, while N2O emission increased from 93.21×104 tons in 1993 to 120.51×104 tons in 2011, and CO2 emission of agricultural production materials increased from 15 626.98×104 tons to 31 258.10×104 tons. CO2 emissions of planting industry were mainly divided into soil emissions and emissions from production materials. Soil CO2 emission was mainly related to atmospheric temperature, soil temperature, surface temperature and soil moisture. CO2 emissions of production materials were mainly caused by fertilizers and pesticides. CH4, N2O emissions of planting industry were more complicated, it remained to be further studied. The influencing factors of CH4, N2O emissions of animal enteric fermentation largely depended on type, characteristics of animal feed, rearing method and manure management methods.关键词
