北方土石山区土壤侵蚀对土壤质量的影响
Effects of Soil Erosion on Soil Quality in the Rocky Mountain Areas of Northern China
摘要
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 cultivated soil on sloping land was 5 961.6 t/km2 · a and that of natural soil was 2 530. 5 t/km2 · a;then the author discussed the influence about soil erosion on soil quality. Results indicated that soil erosion was very severe among the whole study watershed. In those areas with greater soil erosion, soil phosphorus content didn't have a notable change, while soil organic matter and total nitrogen content were low relatively. So the soil quality was poor in general. There was a positive meaning of the study about land resources' reasonable development and utilization and environment protection in the rocky mountain areas of northern China.关键词
