| 摘 要： | 对陕西长武XCMD剖面进行了粒度和磁化率测量、分析,发现:(1)在整个剖面中,土壤质地都属于粉土。(2)磁化率与粒级<1μm的颗粒含量相关性不明显;与1～10μm粒级颗粒含量呈明显的正相关,与10～50μm及>50μm粒级颗粒含量呈负相关关系。(3)1～10μm粒级颗粒含量在一定程度上可以反映夏季风的强弱,而10～50μm及>50μm粒级颗粒含量可以在一定程度上可以反映冬季风的强弱。

| Abstract: | By measuring and analyzing the granularity and magnetic susceptibility of the soil in XCMD profile of agricultural cultivated land in Changwu area of Shaanxi province,we found that:(1) the soil texture belonged to silt;(2) magnetic susceptibility was not obviously correlated with the content of particle whose granularity is less than 1 μm,was significantly positively correlated with the content of particle with 1～10 μm grain size,and was negatively correlated with the content of particle whose grain size is 10～50 μm or larger than 50 μm;(3) the content of particle with 1～10 μm grain size could reflect the strength of summer monsoon to a certain extent,while the content of 10～50 μm or >50 μm particle could reflect the strength of winter monsoon to a certain extent. |
