چکیده
Responses: Thanks for the question which is really valuable. The snowmelt period is partly included in the growing season. In the Sanjiang Plain, the surface sonw begins to melt usually at middle April and disappeared completely in early May in the mires, while in farmland, surface snow disappears in late April. But in fact, it is not the important factor affecting the DOC flux. In the Sanjiang Plain, the land surface is very flat with a infinitesimal land gradient in our study area. As most part comverted to farmland, the study area export little runoff from sonwmelt in the fluvial systems. On the other hand, the snowmelt here indicates only the melt of surface snow above mire surface, not the surfacial peat and soil in frozen with ice. The melt of surface peat and soil begins in May. In fact, I had collected the water samples in the degraded mire and ditches with little runoff in middle and late April in 2010. But the content of dissolved carbon is too low because the runoff only came from the surface snow. So I deleted the data to meet the consistency in the sampling time in 2009. So there is no the greateast amount of DOC flux missed in the research.

متن کاملDistribution characteristics of dissolved organic carbon in annular wetland soil-water solutions through soil profiles in the Sanjiang Plain, northeast China.
Overwhelming evidence reveals that concentrations of dissolved organic carbon (DOC) have increased in streams which brings negative environmental impacts. DOC in stream flow is mainly originated from soil-water solutions of watershed. Wetlands prove to be the most sensitive areas as an important DOC reserve between terrestrial and fluvial biogeosystems. This reported study was focused on the di...
