- Intervention effect Warming and nitrogen application shortened the decomposition periods of Leymus chinensis and Phragmites communis litter, by the Olson model.
- Mechanism Bacterial biomass is proposed as the most important factor during litter decomposition of the two species.
- Association Litter decomposition quality was positively correlated with organic C content of the litter.
- Observation Total nitrogen and total phosphorus content in litter showed settling phenomena.
