摘要

通过对江西省红壤地区的39个土壤剖面采样数据进行数理统计分析

发现在土壤表层20cm范围内

不同土层

137

Cs含量与土壤粒径具有一定的相关性

其中与砂粒含量和粉砂粒含量具有正相关关系

与砾石含量和黏粒含量具有负相关关系。通过逐步回归分析发现

在各土层与

137

Cs含量关系最为密切是砂砾含量

两者呈现显著的正相关关系。同时建立了

137

Cs含量与砂砾含量的定量关系模型

并通过方差分析证明该模型可靠

但该模型应用于土壤侵蚀还需要进一步研究。

Abstract

The 137Cs tracing method is extensively used in the research fields of soil erosion and sediment transportation.For using the method

it is very important to determine the relationship between 137Cs and the composition of soil particles.However

at present

research on this aspect is not well conducted.So

based on the data of 39 soil profiles in different areas of red soil

this paper analyzed the relationship between 137Cs content and the composition of soil particles using statistical methods.The result showed that 137Cs had a positive correlation with sand and silt contents

and had a negative correlation with gravel and clay contents within 20 cm of the soil surface.Then through correlation analysis and stepwise regression analysis

it was found that in different layers

sand content was the main factor contributing to 137Cs.The quantitative model for the relationship between 137Cs and the composition of soil particles was constructed.The model showed that 137Cs increased with the increasing of sand content.
