摘要

采用野外采样和室内分析相结合的方法

研究宁镇地区黄棕壤坡地7Be的季节性沉降与分布

初步分析了坡地的季节性侵蚀状况。结果表明:研究时段内该地区背景值剖面中的7Be主要分布在土壤表层0-8 mm

7Be在土壤剖面中的分布随深度呈现指数递减;背景值点研究时段前后的7Be含量分别为208.35Bq/m2和250.84 Bq/m2。坡地覆盖植物对7Be沉降的拦截吸收以干枯植物最大

人类耕种植物最小;3块坡地中撂荒地的7Be平均含量最大

时空变异却最小;对季节性侵蚀示踪的结果表明

各坡面均在凸地形发生侵蚀

凹地形发生沉积。

Abstract

In this work

the seasonal settlement and distribution of 7Be were measured and the seasonal soil erosion on slope was also preliminary analyzed with the method of field sampling and laboratory analysis in Ningzhen region.The results showed that during the period

7Be of the reference profile in the region

mainly distribute in the surface soil(0-8 mm) and the distribution of 7Be in the soil profile decreased exponentially with depth;7Be of the reference inventories were 208.35 Bq/m2 and 250.84 Bq/m2 at the pr...
