1980-2011年福建省农业甲烷排放估算研究
Estimation of the amount of agricultural methane emission in Fujian Province from 1980 to 2011 based on model CH4 MOD and GIS
摘要
Abstract
Based on the agricultural production data collected in Fujian province from 1980 to 2011,this paper establishes a framework to estimate the amount of agricultural methane emission during that period by using the combined work of modeling methane emission from rice paddies and GIS spatial database.The results show that:(1) the amount of Methane emission experienced a decrease in Fujian province from 1980 to 2011,accounting for almost 1 219.71 × 104 t in total,which means the rate is declining year by year;(2) The highest mount of agricultural methane emission appeared in Nanping,Longyan and Zhangzhou,accounting for 47％ in total;(3) During the 32 years,the amount of methane emission in rice paddies is 877.63 × 104 t in Fujian,showing an overall decreasing trend with an annual rate of 1.96％.Animal intestines and livestock manures methane emission showed a clearly increasing trend,with average annual growth rates of 1.04％ and 2.25％ respectively;(4) The amount of methane emission from different agricultural sources is quite different.Paddy is the main source of agricultural methane emission,accounting for 72％ in total,while animal digestive tract accounts for 23％ and livestock manures accounts for 5％.Controlling the rice paddy soil organic matter is a vital point for the paddy CH4 emissions management;(5) The estimated model of 2025 shows that the amount of agriculture CH4 emission reduces overall in Fujian province.Meanwhile,to enhance the efficiency of ruminant feed and animal waste management has become an important point for the development of agriculture in Fujian.关键词
