Abstract

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.
