| Abstract: | In this paper,19 survey sites in the typical steppe of the Xilin Gol Plateau and Hulunbeier Plateau in Inner Mongolia were selected.As the representative of typical steppe,the state of Leymus chinensis+Stripa grandis vegetation was surveyed in the long term of in sustained and superstrong grazing.According to the research of the grassland ecosystem health assessment,we calculated the vigor and the resilience of different plant communities combining with the characteristics of the typical steppe ecosystem an... |
