摘要

系统介绍了

Be核素侵蚀示踪技术的原理和方法。

Be核素侵蚀示踪技术提供了短时期季节性或单次降水事件的水土流失信息

可为水土流失监测

土壤侵蚀模型试验研究提供重要信息数据。

Be核素侵蚀示踪技术具有不受场地限制、简便快捷

省时省力等特点。对工程建设弃土弃渣水土流失的监测

不用建立把口站或径流小区

只须在雨季后采一次样

或雨季(单次降雨)前后各采集一次样品

利用

Be核素侵蚀示踪技术就可精确估算出其水土流失量。

Abstract

Cosmogenic environmental radionuclide 7Be

produced primarily by the bombardment of the earth＇s atmosphere by cosmi crays within the troposphere and stratosphere

has a similar environmental chemical behavior as137Cs and 210Pb. With a hal-f life of 53.3 days

7Be can be used to document short-term rates

patterns and seasonal variations of soil redistribution or sediment deposition representing the influences of a specific landuse or a particular event in a period of precipitation. Potential application of the information on soil erosion and redistribution provided by 7Be measurements can clearly include the validation and calibration of distributed event-induced soil erosion and sediment delivery models. 7Be technique

a potential alternative to 137Cs and 210Pb in situations where information on short-term or event-based soil erosion is required

is considerably promising in soil erosion tracing

such as soil erosion on debris from project construction.
