摘要：

气候变暖对森林生态系统结构和功能有重要影响。利用开顶式增温室(Open Top Chamber,OTC)模拟气温升高,研究增温对内蒙古大青山油松人工林土壤理化性质的影响,揭示全球增温对土壤生态系统的可能影响机制。结果表明:1)使用的OTC装置在模拟增温1年后,大气温度较对照平均升高了0.65℃,其中夏季增温幅度最大(1.18℃),冬季增幅最小(0.24℃);大气湿度较对照增加了0.83%,其中秋季增湿幅度最大(1.75%),冬季增幅最小(0.12%)。2)土壤层5,10,20,40cm温度分别较对照升高了1.07,1.41,1.12,0.59℃。增温导致各层土壤湿度下降,其中,土壤层5,10,20cm分别较对照降低了4.26%,3.86%,6.5%;下层40cm土壤湿度较对照升高了1.37%。3)增温使得土壤pH值升高,其中,0~10cm土层较对照增加了0.07,10~20cm土层增加了0.9。4)增温使得生长季土壤碳、氮含量均有所下降,其中,0~10cm表层土壤有机碳、易氧化有机碳、全氮含量、分别较对照降低了12.79%,11.28%,5.32%;10~20cm土层分别降低了8.57%,11.43%,1.79%。增温同时降低了土壤的碳氮比,其中土层0~10cm和10~20cm分别较对照降低了10.47%和9.14%。

Abstract:

Climate warming has an important impact on the structure and function of forest ecosystems. The effects of warming on soil physical and chemical properties of Pinus tabulaeformis plantations in Daqing Mountain of Inner Mongolia were studied by open top chamber (OTC) to simulate temperature rise,and the possible mechanism of global warming on soil ecosystem was revealed. The results showed that :1) After simulated warming for 1 year,the atmospheric temperature of the OTC device increased by 0.65℃ on average compared with the control,with the largest increase in summer (1.18℃) and the smallest increase in winter (0.24℃). Atmospheric humidity increased 0.83 % compared with the control,with the largest increase (1.75%) in autumn and the smallest increase (0.12%) in winter. 2) Soil temperature at 5,10,20 and 40 cm depth increased by 1.07,1.41,1.12 and 0.59℃,respectively. The warming led to the decrease of soil moisture in each layer,in which the soil layers at 5,10 and 20 cm were 4.26%,3.86% and 6.5% lower than those of the control,respectively. The soil moisture in the lower 40 cm layer increased by 1.37% compared with the control. 3) Warming increased soil pH,0~10cm soil layer increased by 0.07,10~20cm soil layer increased by 0.9.4) Warming decreased the contents of soil carbon and nitrogen in the growing season,and the contents of soil organic carbon,readily oxidized organic carbon and total nitrogen in the surface layer of 0~10cm were 12.79%,11.28% and 5.32% lower than those in the control,respectively. These indicators in the 10~20cm soil layer decreased by 8.57 %,11.43%,1.79% respectively. Warming also reduced soil C/N ratio,in which 0~10 cm and 10~20 cm decreased by 10.47% and 9.14%,respectively.
