The NO emission rate was considerably higher in palustrine wetlands compared with lacustrine and riverine wetlands. However, the COand CHemissions did not differ significantly among the three wetland types. The ratio of COto CHproduction increased with increasing incubation temperatures. The global ...
After reclamation, SOC density in three types of wetland soils decreased, and SOC density in soybean field were higher than that in paddy field. Either in wetlands or farm lands in the three types of wetland soils, most of the SOC storage in 0-100 cm soil layer was stored in 0-50 cm...
Ecosystem–atmosphere exchange of CH4 and N2O and ecosystem respiration in wetlands in the Sanjiang Plain, Northeastern China three wetland types, which suggest the uncertainties in previous studies in which all kinds of natural wetlands were treated as one or two functional types...

Bodies of water usually show dark, with different tones depending on water depth and clarity. Vegetation types can be discerned from their textures, tones, and colours, though the last two of these can vary between seasons. This example (Fig. 98) shows a coastal plain where wetlands have ...
We used oligotrophic, P-limited herbaceous wetlands of northern Belize to assess how changes in nutrient availability impact species composition and ecosystem processes. The P, N, and NP enrichment plots were established in replicated marshes of three salinity levels to document potential salinity constr...
A riparian zone refers to land that is periodically exposed or submerged due to seasonal fluctuations of water levels in rivers, lakes, and reservoirs. These zones belong to the broad category of wetlands. Changing water levels in riparian zones may occur due to natural causes, such as seasonal...

Wetlands provide important ecosystem functions for water alteration and conservation of bio-diversity, yet they are vulnerable to both human activities and climate changes. Using four decades of Landsat and HJ-1A/1B satellites observations and recently developed classification algorithms, long-term wetlan...
south of Qinghai Province, where unique Alpine wetlands are distributed including a mass of rivers, lakes and marshes, and surveys and collects the data on types, area and distributions of the wetland sites with an area of more than or equal to 100hm~2 in the Three Rivers' Source Region....
