英文摘要	Soil respiration plays a key role in the carbon budget and carbon cycle of terrestrial ecosystems. To examine soil respiration response to fertilizer application and water addition, soil respiration was measured in a semiarid region of northeast China. We examined the effects of fertilizer application, water addition, and their interactions on soil respiration in a randomized block experiment, analyzed by repeated-measures ANOVA. The results indicated that the effects of fertilization on soil respiration were dependent on water addition, in 2010. However, soil respiration after fertilizer application was not significantly different from the control, in 2011, under the same water conditions. Soil temperature clearly affected soil respiration, and explained 9.8-22.5% of the variation in soil respiration of 2010, and 25.8-48.3% in 2011. However, soil water dynamics has an overriding influence on soil respiration in Horqin Sandy Land. A simple empirical model indicated that soil water content explained 22.7-86.1% of the soil respiration dynamics under water and fertilization treatments. Compared to temperature, we found that soil moisture has an overriding effect on soil respiration in Horqin Sandy Land.
