Genetic diversity of Stipa grandis under different grazing pressures;

Effect of Different Utilization Regimes to the Quantitative Characteristics of Stipa grandis Population;

An analysis of genetic differentiation between Stipa grandis populations in middle and eastern Inner Mongolia steppe;

Dynamic study of nutrilite and digestibility of the herbage on Stipa grandis steppe under the different grazing system;

Community features of Scarabaeoidea larvae in Stipa grandis steppe;

Variation of plant population on different grazing gradients, that is, no grazing (CK),light grazing (LG), moderate grazing (MG) and heavy grazing (HG), were studied on Stipa grandis steppe in the Grassland Ecosystem Station of Chinese Academy of Science in Xilmguole League.

Stipa grandis grassland productivity and utilization in Inner Mongolia: Ⅰ. Dynamics of standing crop of pastures in grazing system;

There are 11 species of grasshoppers (Acridoidae) on the Stipa grandis grassland in Xiling Gol River region in Inner Mongolia.

Community structure and biomass of Leymus chinensis community and Stipa grandis community were surveyed and quantitatively analyzed at inner Mongolia grassland ecosystem research station of the Chinese academy of sciences in 2006 growth period.

The result showed that the mineral oil content of soil was negatively correlated with microorganism contents,the mineral oil accumulation degree of stipa was more than that of Leymus chinensis and the Fe and Zn accumulation degree of Leymus.
