Profile distribution characteristics of organic carbon (C), total nitrogen (N), total phosphorus (P) and total sulfur (S) were studied in two typical marshes including Carex lasiocarpa marsh and Phragmites australis marsh in the Sanjiang Plain. Sedimentary characteristics of typical mashes were analyzed. The results showed that vertically these soil chemical elements also varied, showing obvious stratification and enrichment.

Article Synopsis
- Stream water samples were collected monthly from March to October 2006 in Liangshui Nature Reserve to study hydrochemical characteristics across different forest types.
- Major cations found were ranked as Ca2+ > Na+ > K+ > Mg2+, while anions followed the order HCO3(-) > SO4(2-) > NO3(-) > Cl(-).
- The spruce-fir forest had higher average contents of Na+, Ca2+, Mg2+, Fe2+, and Fe3+, while K+ was highest in the larch plantation, which also showed the highest average monthly anion content.
The study on the profile distribution and accumulation characteristics of organic carbon (C) and total nitrogen (N) in two typical marshes in Sanjiang Plain showed that on the sediment profiles of Carex lasiocarpa marsh and Phragmites communis marsh, there existed distinct deposition horizon and illuviation horizon. In deposition horizon (0-60 cm), the average contents of organic C and total N were about 96 and 184 g x kg(-1), and 7.4 and 17.
