| 摘 要： | 以放射性核素7Be为研究手段,对内蒙古阴山北麓开垦草原区春季土壤中的放射性核素7Be含量的连续性动态变化规律及土壤剖面中7Be含量的垂直变化特征进行了尝试性研究.由于7Be主要随降雨到达地表,而研究区春季(3~6月)降水很少,使得该时间段的7Be沉降量很小,在土壤表层没有形成明显的分布规律,因此,7Be不能作为估算开垦草原土壤风蚀量的示踪剂.

| Abstract: | In this paper,the attempt study on wind erosion in ploughed grassland in the north foot of Yinshan mountain by method of 7Be tracing with a series of field observations and experiments for the tracer's continuous variability orderliness and the vertical distribution characteristic in soil section was given.The results showed that 7Be is mostly reached on the soil surface with rain,and rainfall is very little from March to June in study area,so that the conduced 7Be subside quantity is very little and there ... |
