| 根据主要农作物产量、耕地面积及农业投入等数据对辽宁省2003-2010 年耕地的碳源和碳汇进行了核算，运用土地利用现状分类和辽宁省统计年鉴中的行业能源消费量等数据，建立了行业能源消费和土地利用类型的对应关系，进而核算了2003-2010 年辽宁省商服用地、住宅用地等土地利用类型的碳源量，同时根据辽宁省2003-2010 年土地利用面积核算了林地和草地的碳汇量。通过核算得出的数据分析发现：辽宁省碳源总量从2003 年的9 276.91 万t 增长到2010 年的11 471.15 万t，增长幅度达23.75%，呈大幅增长的趋势，其中工矿仓储用地的碳源量占总碳源量的比重最高，2010 年比重达77.59%，其次分别是耕地、住宅用地、商服用地、交通运输用地。辽宁省地均碳排放量由2003 年的6.25 t/hm2增长到2010 年的7.73 t/hm2。辽宁省2003-2010 年碳吸收量呈小幅变化，从2003 年的3 294.38 万t 减少到2010 年的3 288.69 万t。 |
| 英文摘要: |
| Through the main crops, cultivated area and agricultural input data, the land of carbon sources and sinks of Liaoning province from year 2003 to 2010 were accounted.Application of current land use classification and the statistical yearbook of Liaoning province in the industry energy consumption data, the industry energy consumption and the corresponding relationship between the types of land use were established.Meanwhile the commercial take, residential land and other land use types of carbon source of Liaoning province from 2003 to 2010 were accounted. By analyzing the accounting data, it was found that since year 2003 Liaoning province carbon source gross showed great growth trend, from 92 769.1 thousand t to 114 711.5 thousand t from 2003 to 2010, the growth was 23.75%.Among them industrial warehouse land carbon source accounted for the highest proportion of total carbon source, which took up 77.59% at 2010，and followed by the cultivated land，residential land，commercial use of land，land for transportation.Carbon emissions had changed from 6.25 t/hm2 to 7.73 t/hm2 in 2003 to 2010 of Liaoning province.From the year 2003 to 2010, Liaoning's Carbon uptake showed a slight change, from 2003's 32 943.8 thousand t reduced to 2010's 32 886.9 thousand t. |
