The Study on Agricultural Non-Point Nitrogen Pollution Control

Article Preview

Abstract:

Purification effects of riparian wetland in a natural state on pollutants are unstable and are always influenced by hydrology, climate, and extent of wetlands development. For this reason, study of the role of the purification function of riparian wetland in a natural state is ongoing. In this study, with the Kouma section of the Yellow River wetlands as the study area, using the field experiment method and the 15N enriched technique, the agricultural non-point nitrogen pollution control function of Phragmites communis Trin in riparian wetlands was studied. Artificial runoff events enabled the collection of a temporal and spatial array of samples within the wetland so that the plume of runoff water moving through the wetland could be traced and its attenuation determined.
