摘要
通过对宁夏固原不同植物过程土壤剖面有机碳含量和含水量的测定和分析.发现人工林和灌木林土壤含碳量和含水量明显高于草地和农田土壤;有机碳含量和含水量分布随土壤深度加深而呈总体下降趋势,人工林和灌木林土壤含碳量和含水量层次间下降比较明显.
The contents of organic carbon and water of different plant processes in soil profile of NingXia GuYuan are measured and analyzed. The result shows that the contents of organic carbon and water in soil profile of plantation and shrubbery are higher than that of grassland and upland obviously. Meanwhile the distribution of the organic carbon and water contents presente a decreasing trend with the increase in soil depth of different plant processes, Comparatively there is a evident decrease of the organic carbon and water contents in different layers of plantation and shrubbery soil.
