CHARACTERISTICS OF BIOMASSES AND SOIL PROPERTIES IN DIFFERENT DEGRADED ALPINE MEADOW GRASSLANDS
The paper analysised the changes of alpine meadow biomasses and soil nutrients about non-degraede meadow,lightly degraded meadow,moderately degraed meadow,severely degraded meadow and black soil land.The resluts showed the plant height,species,fresh weight,dominated plant fresh weight and below ground biomass were 4.08 cm,16.33 species/m2,369.60 g/m2,60.53 g/m2 and 10.07 g/m2,which were themaximum values and significantly higher than other treatments(P≤0.05).Biomass had significantly correlation with the soil organic matter and soil nitrogen(P≤ 0.05).
