Wetlands are viable sinks for nitrate and have also been identified as a source of nitrous oxide, product two microbially regulated processes: nitrification denitrification. Anthropogenic expansion nitrogen is leading cause the eutrophication water bodies may contribute to deterioration ozone layer in stratosphere. ameliorate quality percolating through them, by retaining nutrients sequestering...

Wetland, as one of the weakest ecosystems in the world, is deteriorating rapidly in many regions. Longfeng wetland is the biggest urban wetland in China, located in the inner of Daqing city, Heilongjiang Province. It is divided into two areas by Wolong road, the east is provincial natural reserve and the west is unprotected. This paper describes a remote sensing change detection approach used t...

To test whether large amounts of phosphorus (P) are accumulated in the floodplain during dry antecedent conditions, and whether they would be released as the predominant source of P in the overlaying floodwater, in accord with the Flood Pulse Concept, we calculated the mass balance of P in an intermittent floodplain wetland after environmental water application. The P mass balance was calculate...

Wetland is a unique ecosystem, rich in biodiversity. It is not only a valuable land resource, it also protects rare animals and plants, therefore it is of high economic value and scientific significance. This paper studies the present situation and development trends of wetland in Guangdong Province, China, with remote sensing technology. The total wetland area of Guangdong Province is 1 864 10...

wetland functions is the monitoring of newly restored wetland sites to determine how quickly wetland functions develop and whether function-based mitigation objectives are being met. This technical note presents a case study of the application of the Western Kentucky Low-Gradient Riverine Guidebook to monitoring the development of wetland functions on a number of bottomland hardwood forest site...

measuring salinity of water at different depths along six transacts at the mouth of the wetland and along five tributaries connecting the wetland to the sea the extent of caspian sea penetration into anzali wetland was determined. the results demonstrated a depth-dependent salinity gradient extending up to 10 kilometres into the wetland. a pattern of saltwater and freshwater interface is presen...
