Xilingol Temperate Grassland Ecosystem Research Station

(Inner Mongolia)

GEOGRAPHY AND PHYSIOGNOMY

      Xilingol Temperate Grassland Ecosystem Research Station (Inner Mongolia) was founded in June, 2001. The station has two observation plots, i.e., typical steppe (Stipa krylovii) plot and desert steppe (Stipa gobica) plot. The typical steppe plot is approximately 24 km northeast of Xilinhot city (44°08′03″N, 116°19′43″E, 1030 m), and  the desert steppe plot is located at the left Sunite Banner (44°05′20″, E 113°34′27″, 970 m), Inner Mongolia Autonomous Region, P. R. China.

CLIMATE

      It is under a temperate arid and semi-arid continental climate with cold and drought winter and warm and moisture summer. For the typical steppe plot, mean annual temperature is about 2.0℃, with a mean minimum of -22.3℃ and a mean maximum of 18.8℃. Mean annual precipitation is around 350mm with 80% from June to September. For the desert steppe plot, mean annual temperature is about 3.1℃, with a mean minimum of -22.0℃ and a mean maximum of 20.4℃. Mean annual precipitation is around 185mm with 70% from July to September.

VEGETATION

       Grassland is the primary vegetation type in this region. It consists mainly of typical steppe and desert steppe. The typical steppe plot is dominated by zonal vegetation, such as S. krylovii and Leymus chinense, and the desert steppe plot also by zonal vegetation, such as Stipa gobica and Allium polyrrhizum.

OBSERVATION SYSTEM (ppt)

     Microclimate gradient system (2m, 4m), open eddy covariance system (2m) and LI-8100 automated soil CO2 flux system are installed in the typical steppe plot and the desert steppe plot.
