Study on the forming mechanism of "black beach" degraded alpine meadow on Qinghai-Tibetan Plateau and the research progress on its restoration;

The status of the "black beach like" degraded grassland in the water replenishment area of upper Yellow River was systematically expounded.

The aqueous extracts from the above-and underground parts of Aerba lupulin, a dominant plant of secondary poisonous weed community on the black soil patch of degraded alpine meadow on Qinghai-Tibet plateau, were used to study their inhibitory effects on the seed germination and seedling growth of four graminaceous grass species on the plateau.

Aerba lupulin and Aconitum pendulum were the dominant weed of degraded alpine meadow‘black soil patch’in Qinghai-Tibet plateau.
