摘  要:
在新疆干旱区绿洲农田区的玛纳斯县选取了180个土壤调查点,测定了耕作层(0~30 cm)有机碳含量,并运用地理信息系统技术和地统计学方法绘制了主要农田区土壤有机碳的空间分布图。结果表明,指数模型可以较好的拟合研究区耕作层土壤有机碳的空间结构,其决定系数达到了显著水平(P<0.05);有机碳主要分布在研究区的西北部和中部区域,东部区域含量相对较低,主要受灌溉及土壤质地等因素的影响,粘质土壤与有机碳含量的相关性达到极显著水平(P<0.01)。

摘  要:
In this paper,180 soil survey points have been selected in Manas County,which is the typical oasis farmland in arid area.The soil organic carbon content of plow layer(0-30 cm) was measured; the spatial distribution of soil organic carbon has been drawn by using geographic information system technology and geostatistics method.The results showed that the index model can better fit spatial structure of soil organic carbon in plough layer in the study area,the determination coefficient of this model reached a significant level.Soil organic carbon is mainly distributed in the northwest and central regions of the study area,a relatively low content in the eastern region.That is mainly affected by irrigation,soil texture and other factors; clayey soil with organic carbon content reaches a significant level.
