摘要: 研究了农田土壤动物和微生物的季节动态与土壤生物化学特征之间的关系,并利用灰色理论与方法进行分析。结果表明,土壤生物和土壤生物化学特征均有明显的季节性变化。而土壤动物和微生物的季节动态与土壤生物化学特征之间也具有明显的相关性。其中关系最大的生物化学特征是过氧化氢酶、脱氢酶、无机磷转化作用和枯枝落叶分解速率。并建立了5个灰色数学模型[GM(1,5)]。

Abstract: The study was made in the heavily frigid region of northeastern China from May to September in1997.The relationship between seasonal variation of soil fauna and microbial biomass and 14 ecological factors was studied, and the primary and secondary factors affecting soil faunas and microorganisms were sought out, in grey connected analysis.Data set was composed of soil faunas and 4 ecological factors (catalase, dehydrolgenase, inorganic Ptransformation and residual decomposition rate). Five grey models[GM(1,5)] were established.

Key words: Soil and water conservation, Runoff-and sediment generation, Forest stand, Loess Plateau
