为确定何种主要养分因子能准确描述土壤有机质含量状况，运用灰色系统论中的灰色关联分析法，系统地研究了不同林草植被模式和不同农田作物种植模式下土壤主要养分因子微生物生物量碳、全氮、速效磷、速效钾及pH 值与土壤有机质之间的灰色关联度。结果表明：不论是林草植被模式，还是农田作物种植模式，土壤有机质与全氮关联度最大，并且二者呈线性关系。

The correlations between the main nutrients under different land-covers change grass configuration mode and different crops grow ( including the microbial biomass C , total nitrogene , available phosphorus , , available potassium , and pH ) and organic matter are experimentally studied .The result of grey correlation shows that the correlation degree between total nitrogene and organic matter rate is the highest of different grass configuration mode , it is also kept as the same of different crops grow , the relationship is linear .
