1. Introduction The wetland is mostly distributed in the moist low temperature area at high latitudes. The wetland has the peat bog, which forms the accumulation of undecomposed plants. The important thing to notice is that the peat bog is similar to the aerial part of biomass in accumulating carbon. Since the amount of carbon cannot be ignored in the wetland, there is an urgent need to monitor...

organochlorine contaminants are highly stable and dangerous compounds, which are widespread in the environment. among these compounds, polychlorinated biphenyls (pcbs) are carcinogenic for humans and can also affect intellectual functions and the nervous, immune and reproductive systems. aquatic organism especially fishes are known to be main routes for e entrance of these compounds to the huma...

Although quarrying is often cited as a potential threat to wetland systems, there is a lack of relevant, quantitative case studies in the literature. The impact of pumped groundwater discharged from a quarry into a wetland area was assessed relative to reference conditions in an adjacent fen wetland that receives only natural runoff. Analysis of vegetation patterns at the quarry wetland site, u...

The Conceptual Wetland Mitigation Plan for Phase II expansion to the John J. Briscoe Reservoir (Briscoe Reservoir) near Monroe, Georgia uses innovative approaches to restoring palustrine wetland functions to existing lacustrine habitats. This paper presents strategies for the design of forested and scrub-shrub wetland habitats in former wastewater treatment ponds and wetland design approach and...

BACKGROUND Since Spartina alterniflora (simplified as Spartina) has strong ecological competitiveness and rapid growth, it has been introduced and living in the coastal wetland regions of China for more than 30 years. Taking coastal wetland in the Beibu Gulf of south China as an example, the effects of Spartina invasion on soil quality were investigated to provide scientific basis for soil mana...

[1] Wetland restoration is a commonly used approach to reduce nutrient loading to freshwater and coastal ecosystems, with many wetland restoration efforts occurring in former agricultural fields. Restored wetlands are expected to be effective at retaining or removing both nitrogen and phosphorus (P), yet restoring wetland hydrology to former agricultural fields can lead to the release of legacy...

Soil organic carbon fractions included microbial biomass carbon (MBC), dissolved organic carbon (DOC), and labile organic carbon (LOC), which was investigated over a 0-20 cm depth profile in three types of wetland in Hongze Lake of China. Their ecoenvironmental effect and the relationships with soil organic carbon (SOC) were analyzed in present experiment. The results showed that both active an...
