A study on the community structure and plant diversity of alpine meadow under different degrees of degradation in the Eastern Qilian Mountains;

Relationships of species diversity and productivity under the fertilization levels in alpine meadow of the Qinghai-Tibetan Plateau;

Effects of soil salt on the niche of main plant species in alpine meadow;

Aims We tested the neutral theory of biodiversity on subalpine meadows of the eastern Tibetan Plateau that exhibited comparatively complicated species composition.

Backed by the large-size Dachang Gold Deposit, the authors made a preliminary study of the supergene process in the western part of the cold and high meadow area in Qinghai Province.

Continuous field experiment was carried out on alpine meadow along different elevation gradient in Qilian Mountains during the growing season of 2004 using a soil respiration chamber(Li-6400-09) connected to a portable photosynthesis system(Li-6400).

),which is covered with alpine meadow,located in the middle reaches of the upper Heihe River,one of the long inland river in Northwest China.

The results showed that in 0-10 cm soil layer,the biomass,length density,surface area density,and volume density of living fine roots were all decreased in the order of evergreen broadleaf forest<dwarf forest<coniferous forest<alpine meadows,with significant differences(P<0.

Grazing impact on soil microbial biomass carbon and relationships with soil environment in alpine Kobresia meadow;

Effects of different land management measures on vegetation productivity on alpine Kobresia meadow

The distribution of N-P and the moisture variation caused by incrassation of the mattic epipedon together with its relationship to pasture degradation by grazing in alpine Kobresia meadow were studied at the Haibei ecosystem research station,Chinese Academy of Sciences.
