针对黄土磁性记录重建古地磁场变迁及黄土^10Be示踪古地磁场变化史的问题.提出了将黄土磁化率作为黄土^10Be浓度受气候因素(降水和降尘)影响部分的代用指标,以及分离黄土^10Be浓度中受地磁场调制和受气候影响的不同组分的思路.在平均值概念(MVC)基础上.引入了气候修正因子,进一步消除了气候因素对^10Be浓度变化的影响:从西峰和洛川黄土剖面的^10Be记录重建了过去80ka、130ka及700~900ka大气mBe产率史.有助于解决中国黄土^10Be环境示踪和重建全球古地磁场变化史的科学难题. “,”In this paper, the difficulties were summarized in the reconstruction of the paleogeomagnetic intensities by using either the paleomagnetie approach or the ^10Be records in Chinese loess; a new idea was put forward that takes the susceptibility as a climate proxy of ^10Be composition affected by climate factors ( Monsoon precipitation and dust flux) to separate the influence of the climate factors from that of the geomagnetic factor on the measured concentration in loess samples. A climate correction factor was introduced into the MVC method based on the mean value concept(MVC) to further clear up the effect of the climate change on the reconstructed results; the past 80 ka, 130 ka and 700 -900 ka ^10Be production rates in atmosphere have been reconstructed, in turn, the global paleogeomagnetie intensities, which have facilitated to solve the academic difficult in environment trace research from ^10Be records in Chinese loess.
