土壤侵蚀调查中的航空^(137)Cs测量方法初探

Primary Discussion on Soil Erosion Investigation Using Aerial Radioactive ^(137)Cs Survey Approach

放射性核素示踪法是土壤侵蚀研究的一种重要方法。通过对土壤侵蚀放射性示踪测量方法国内外研究进展的介绍和分析 ,提出基于航空放射性测量的土壤侵蚀定量监测方法 ,并介绍了测量系统的组成、数据处理流程、放射性元素 1 37Cs含量的计算方法以及土壤侵蚀模数的相关计算模型 ,为土壤侵蚀调查工作提供了一套高效、快捷方案 ,并指出当前航空能谱土壤侵蚀调查应用和研究的重点。

It is an important method to investigate soil erosion that using radionuclides tracks down.On the basis of situation of this study in the world,a method of ARS based(ARS airborne radioactive survey)is provided to study soil erosion quantitively,and meanwhile a series of procedure and model related with this method,such as the constitute of the survey system,the flow of data processing,the algorithm of 137 Cs consistency,and the calculating model of soil erosion modulus,is presented.The current emphasis of the study and application is pointed out.It is an efficient,speedy way in the field of soil erosion study.
