Response of a desert plant Reaumuria soongarica to past geological and climatic change in arid Central Asia
- 第十一屆國際旱地發展會議——Past geological and climatic events have promoted intraspecific divergence and range shifts in numerous plant species. This is particularly true for temperate species in climate-sensitive regions. However, few previous studies have examined so far whether such genetic footprints were also shaped in desert plants, which can survive in arid habitats and might be “static” under the past climatic oscillations. We therefore studied the phylogeographical history of Reaumuria soongarica, a shrub species that is widely distributed across the deserts of arid Central Asia.

Pursuing sustainable desertification reversion through establishment of water-saving vegetations in Horqin Sandy Land in Inner Mongolia
- 第十一屆國際旱地發展會議——Horqin Sandy Land once was one of the most severely desertified lands in northern China. Since 1987, desertification is reversed and vegetation restored. However, monitoring found that both the reversion and restoration were fragile to the climatic change and rapidly increasing water use. The desertified land had increased from 4230 km²in 1975 to 61008 km²in 1987 and then decreased to 50197 km²in 2000 and less than 50000 km²in 2010. While desertification is reversed, the biological productivity of restored desertified grassland was decreased from 380 g/m²in 1982 to 220 g/m²in 2005 and increased to about 380g/m²in 2010 and the diversity was decreased.
