【摘要】：采用土壤學(xué)常規(guī)實(shí)驗(yàn)研究了小興安嶺原始紅松林和人工紅松林土壤酶活性和土壤理化性質(zhì)的時(shí)空變化及兩者之間的相關(guān)性。結(jié)果表明:土壤酶活性及土壤理化性質(zhì)各項(xiàng)指標(biāo)整體上表現(xiàn)為9月份最高,表層土壤(0h≤5 cm)高于下層土壤(5 cmh≤20 cm),且差異顯著。原始紅松林土壤葡萄糖苷酶、酸性磷酸酶、過氧化氫酶活性低于人工紅松林,土壤多酚氧化酶和土壤脲酶活性卻相反;土壤理化性質(zhì)各項(xiàng)指標(biāo)以原始紅松林較高,土壤理化性質(zhì)和土壤酶活之間具有顯著相關(guān)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，
