中文摘要	选择章古台地区三块典型樟子松(Pinus sylvestris var. Mongolica)人工固沙林为研究对象,采用实验室好氧培养法测定了不同土壤层次和在不同水分条件下的N矿化过程.结果表明:土壤0-60 cm 层N净矿化速率垂直变化范围为1.06-7.52 mg·kg-1·month-1;土壤层次和含水量及其交互作用对土壤N净矿化速率的影响均达到差异显著(P<0.05);净矿化速率随着土壤层次的加深而明显下降,0-15 cm层占总净矿化量的60.52%;半饱和与饱和含水量处理差异不显著,但均高于不加水处理.为此,在半干旱地区必须进一步加强开展调控生态系统N矿化、循环及其收支平衡影响因素的研究.
英文摘要	The rates of soil N mineralization at soil depths of 0-15, 15-30, 30-45 and 45-60 cm and moisture regimes were measured at three sand-fixation plantations of Pinus sylvestris var. mongolica by laboratory aerobic incubation method. The results showed that average rates of soil net N-mineralization across soil depth varied from 1.06 to 7.52 mg·kg-1·month -1at soil depths from 0 to 60 cm. Statistical analyses indicated that the effects of different soil depths, moistures and their interactions on net N-mineralization rates were significant (P < 0.05). The net N-mineralization rates significantly decreased with increasing soil depths and at depth 0-15 cm accounted for 60.52% of that at depth of 0-60 cm. There was no difference in soil net N-mineralization rates between half and fully-saturated water treatments, however these rates were substantially higher than that without water treatment (P < 0.05). The factors influencing N mineralization process have to be studied further in these semiarid pine ecosystems.
