【摘要】：采用土壤学常规实验研究了小兴安岭原始红松林和人工红松林土壤酶活性和土壤理化性质的时空变化及两者之间的相关性。结果表明:土壤酶活性及土壤理化性质各项指标整体上表现为9月份最高,表层土壤(0h≤5 cm)高于下层土壤(5 cmh≤20 cm),且差异显著。原始红松林土壤葡萄糖苷酶、酸性磷酸酶、过氧化氢酶活性低于人工红松林,土壤多酚氧化酶和土壤脲酶活性却相反;土壤理化性质各项指标以原始红松林较高,土壤理化性质和土壤酶活之间具有显著相关性。
[Abstract]:The temporal and spatial changes of soil enzyme activity and soil physical and chemical properties of Pinus koraiensis and Pinus koraiensis forests in Xiaoxinganling were studied by conventional soil experiments. The results showed that the soil enzyme activity and soil physical and chemical properties were the highest in September, and the surface soil was higher than that in the lower soil (5 cmh 鈮，
