Root system ecology of shrubs in Qilian Mountains alpine rhododendron shrubland
The Qilian Mountains National Nature Reserve located in the northeastern edge of Qinghai‐Tibet Plateau is the key areas for global climatic change research.The alpine Rhododendron‐shrubland survived above 3,000m in protection area has been attracting the attention for its important ecological services function, and is also the summer‐pasture for rare white yak and other herbivores.Under global warming background, what or how the impact caused on the shrubland ecosystem by increasing human disturbance are the main reasons of this study.From root system ecology to understand belowground ecological characteristics and response of ecological process to disturbance could provide belowground ecological data and theoretical support for scientific utilization and conservation, however, alpine shrub root system studies were seldom found.The root system architecture and spatial distribution of 16 shrub species existing in alpine Rhododendron shrubland were studied, and the relationship with environment were discussed.
