摘要

在生态环境敏感区—太湖周边选择两个地质构造不同的山体

运用137Cs示踪法分析了137Cs分布和土壤侵蚀规律。结果表明:沉积岩山体黄棕壤的137Cs含量表层大于底层

岩浆岩山体黄红壤137Cs含量中部高

表层和底层低。岩浆岩山体坡面的土壤侵蚀变化情况为:坡顶>坡上部>坡中部>坡底;沉积岩山体坡面土壤侵蚀变化为:坡中部>坡下部>破上部。研究区土壤侵蚀整体而言为微度或轻度侵蚀

在太湖周边区域未经人为扰动的山体表土移动运输程度很小

不会对山前平原和太湖水体造成明显影响

土壤流失不显著。

Abstract

Two different geological formations of mountains of ecological sensitive areas around Taihu lake were selected

and 137Cs tracer method was used to analyze the137Cs distribution and soil erosion rules.The results showed that: The137Cs content on the surface of yellow brown soil of sedimentary rocks was more than at the bottom

while the137Cs content in central of rocky body yellow red lava was higher than on the surface and at bottom.Soil erosion variances along body of magma rocky slope were: top of the hill...
