摘要

采用1990-2009年农作物产量、农田生产投入等统计数据

对中国农田生态系统碳排放、碳吸收和碳足迹进行估算

得到以下主要结论:碳排放量和碳排放强度、碳吸收量、碳足迹呈现增加趋势

碳吸收强度表现稳定

随着农用化石能源的大量使用

单位面积碳足迹从1990年的0.08hm2/hm2增加到2009年的0.13hm2/hm2。各省(市、自治区)单位面积碳足迹差异十分明显

2009年最高的福建为0.27hm2/hm2

最低的黑龙江为0.08hm2/hm2。中国农田生态系统存在碳生态盈余

碳足迹占同期生产性土地面积(耕地)的比例在10%左右

但随着年份的递进

所占比例有增大的趋势

1990年为8.46%

2009年为12.75%。

Abstract

Based on the statistic data of crop yield and farmland produce investment in the period from 1990 to 2009

carbon emission

carbon absorption and carbon footprint of the farmland ecosystems were estimated in China.Conclusions were reached as follows:Carbon emission amount and intensity

carbon absorption amount

and carbon footprint on the increase

carbon absorption intensity was stable

with the large number of agricultural use of fossil energy

carbon footprint per unit area of 0.08 hm2/hm2 rose from 1990 to 20...
