摘  要：
运用2004-2013年陕西省的年均气温、农用地(耕地、林地、园地、草地)面积统计数据,小麦、玉米、水稻等农作物产量统计数据以及公开发表的同类文献中的相关参数,采用生态经济学的估算方法对2004-2013年农用地植被的碳汇量以及动态变化进行分析。结果表明,陕西省农用地植被碳汇量随年均温度的显著变化而出现明显的差异变化,但大体仍呈现出增加的趋势。研究期内植被碳汇量增加了3.33×1010t;耕地植被的碳汇量主要来自于小麦、玉米和水稻,这三大作物的植被碳汇量均在11t/hm~2以上;林地和园地的面积与其植被碳汇量相关性不显著,草地面积则与其植被碳汇量变化趋势基本一致;以年均气温为代表的气候是决定林地和园地植被碳汇量大小的主要因素,草地面积是决定其植被碳汇量大小的主要因素。

摘  要：
According to the ecological economics assessment methods,this study analyzed the dynamic change of the carbon sequestration by agricultural land including arable land,forest land,garden land and grass land in Shaanxi from 2004-2013. The data comes from annual average temperature,agricultural land area,the main crops' production and the related parameters of similar published papers. The results showed that the total carbon sequestration of different agricultural vegetation had obvious changes with the difference of the annual average temperature and was increasing in study period in Shaanxi,increased by 3. 33 × 1010tons; The carbon sequestration mainly from wheat,corn and rice,and the amount of each crop was above 11 t/hm~2; The area of forest land and garden land had no significant correlation with carbon sequestration,grassland area had the same change trend with its carbon sequestration; The climate factor represented by average annual temperature was the main factors of carbon sequestration of forest land and garden land,the grass land area was the main factor for grassland vegetation carbon sequestration.
