摘要

沂蒙山区是我国北方典型的土石山区

当地土壤由片麻岩、砂岩发育而来

质地疏松易流失

目前缺乏对土壤侵蚀监测的长期观测数据。以山东省沂蒙山区某一小流域为研究对象

利用137Cs示踪技术与杨氏土壤侵蚀等模型

对该流域坡耕地与非耕地的土壤侵蚀速率进行了初步估算

坡耕地土壤侵蚀速率5 961.6 t/km2.a

坡地非耕地侵蚀速率2 530.5 t/km2.a

并探讨了土壤侵蚀对土壤质量的影响。研究结果表明:整个研究流域土壤侵蚀严重

土壤侵蚀量大的区域

土壤有机质、全氮等含量相对较低

而土壤全磷含量变化和缓

总体上土壤质量状况较差。该研究对我国北方土石山区土地资源的合理开发利用和生态环境保护具有积极的意义。

Abstract

Yimeng mountain area is the typical rocky mountain areas of northern China.The local soil with loose texture and easy to lost was developed from the gneiss and sandstone.Currently

there is lack of the long-term observation data of soil erosion.A small watershed in Yimeng mountain area of Shandong Province was chose to make a preliminary estimate about soil erosion rates of natural soils and cultivated soils on sloping land using the 137Cs tracer method and soil erosion model of Yang.The erosion rate of cult...
