Effects of grazing on carbon and nitrogen in plants and soils in a semiarid desert grassland,China被引量：34
《Journal of Arid Land》2015年第3期341-349,共9页Hui AN GuoQi LI 
financially supported by the National Natural Science Foundation of China (31260125,31000214)
Grazing can modulate the feedback between vegetation and soil nutrient dynamics（carbon and nitrogen）,altering the cycles of these elements in grassland ecosystems.For clarifying the impact of grazing on the C and N ...
