The results showed that the CO_2 fluxes were significantly different between the swamp meadow and alpine meadow ecosystems and between the different degenerate meadows, correspondingly.
采用静态箱—便携式红外色谱法对青藏高原风火山地区沼泽草甸和高寒草甸两类生态系统CO_2排放通量进行了研究。
The responses of environmental factors to long-term experimental warming and their relationships with the near-surface air CO_2 concentration in the swamp meadow areas on the Qinghai-Tibetan Plateau were studied using OTCs systems with 3～5℃(OTC-80) and 1～2℃(OTC-40) elevated respectively.

Release process and kinetics of naturally occurring water soluble organic compounds from sediment and riverside wetland soil were investigated.
模拟研究了沉积物与草甸沼泽土中水溶性天然有机物从固相向水相释放的动力学过程，探讨了流速、温度和ｐＨ条件对土壤和沉积物中水溶性有机物释放速度的影响。
Contents and sorption coefficients of sediment and soil samples from Yichun River catchment were measured using a Multiple Solid-Water Ratio Procedure.
研究结果表明，草甸沼泽土中水溶性有机物含量最高，沉积物中含量最低。
