[effect of degradation succession process on the temperature sensitivity of ecosystem respiration in alpine potentilla fruticosa scrub meadow]. | grazing is one of the main artificial driving forces for the degradation succession process of alpine meadow. in order to quantitatively study the temperature sensitivity of alpine meadow ecosystem respiration in different degradation stages, we conducted the research in haibei alpine meadow ecosystem research station, cas from july 2003 to july 2004. the static chamber-chromatography methodology was used to observe the seasonal changes of alpine scrub ecosystem respiration flux during different ... | 2015 | 25929079 |
[relationships between belowground biomass of alpine grassland and environmental factors along an altitude gradient]. | taking bayanbulak alpine grassland on the southern slope of tianshan mountain, xin-jiang as test object, the relationships between belowground biomass and environmental factors along an altitude gradient were analyzed. the results showed that with increasing altitude, the below-ground biomass of alpine steppe dominated by stipa purpurea and festuca ovina, alpine steppe meadow dominated by kobresia capillifolia and s. purpurea, and alpine meadow dominated by carex stenocarpa, alchemilla tianschan ... | 2008 | 19238833 |
[effects of soil salt on the niche of main plant species in alpine meadow]. | by using levins niche breadth index and cowell similarity index, the niche breadth and niche similarity of main plant species in bayanbulak alpine meadow were calculated, based on 3 resources dimensions (soil moisture, organic matter, and available k) along four gradients of soil salt content. the results showed that with the increase of soil salt content, the average niche breadth of main constructive species carex stenocarpa based on the 3 resources dimensions decreased from 0.4433 to 0.1740, ... | 2008 | 18839902 |
[relationships between aboveground biomass and environmental factors along an altitude gradient of alpine grassland]. | in order to analyze the relationships between aboveground biomass and environmental factors along an altitude gradient of bayanbulak alpine grassland on the southern slope of tianshan mountain, nine plots were selected, with each at 100 m interval of altitude. the results showed that stipa purpurea and festuca ovina communities distributed at the altitude from 2460 to 2760 m, and the aboveground biomass were 52.2-75.9 g x m(-2). kobresia capillifolia + s. purpurea communities distributed at alti ... | 2007 | 18062306 |
ectomycorrhizal fungi associated with two species of kobresia in an alpine meadow in the eastern himalaya. | the diversity of ectomycorrhizal fungi (emf) on kobresia filicina and kobresia capillifolia in an alpine meadow in china's southwestern mountains, one of the word's hotspots of biodiversity, was estimated based on internal transcribed spacer rdna sequence analysis of root tips. seventy emf operational taxonomical units (otus) were found in the two plant species. dauciform roots with emf were detected in species of kobresia for the first time. otu richness of emf was high in tomentella/thelophora ... | 2010 | 20012655 |
