Research Abstract

Recently, droughts have become widespread in the Northern Hemisphere continent, having a substantial effect on Mongolian grasslands in the quantitative (such as biomass) and qualitative (such as phenology) aspects. In order to investigate the ecosystem response to such a drought, an artificial drought experiment (DREX) with a rainout shelter was conducted at Bayan Unjuul (105.95°E, 47.04°N) in the typical steppe region during the growing summer rainy season of 2005. The present drought experiment is the first attempt in the Asian dryland. Results showed that the drought manipulation with a dry spell that occurs statistically once in half-one century resulted in drastic reductions in aboveground biomass (AGB), soil moisture, soil organic carbon, and total nitrogen, but not in a significant reduction in underground biomass (UGB). This drought impact was followed by a quick recovery in the AGB in the late summer of 2006, likely on the basis of the UGB having a biomass several times as much as the AGB. However, the drought-sensitive species, soil organic carbon, and total nitrogen have not yet revealed recovery as prior to the drought, suggesting the different time scales of responses for each ecosystem element.
