摘    要:采用野外调查和室内分析相结合的方法对石羊河流域耕地、草地、林地、未利用土地的土壤有机质、全氮、全磷和全钾含量进行对比研究.结果表明:4种土地利用方式下,草地和林地土壤有机质和全氮含量显著高于耕地和未利用土地,依次为草地>林地>耕地>未利用土地,草地土壤有机质含量高(>40 g/kg)的样本占总样本的40%以上,但草地和...

关 键 词:石羊河流域  土地利用方式  有机质  全量养分

Abstract:The contents of soil organic matter,total nitrogen,phosphorus and potassium in cropland,grassland,forest land and unused land in Shiyang Basin were determined and compared by the method of field investigation combining laboratory analysis.The results showed that the contents of soil organic matter and total nitrogen in grassland and forest land were both significantly higher than those of cropland and unused land,the samples of grassland with high content of soil organic matter(>40 g/kg) occupies more than ...
Keywords:Shiyanghe Basin  land-use pattern  soil organic matter  total nutrients
