This paper uses CiteSpace to visualize and analyze the literature related agricultural non-point source pollution in China Knowledge Network (CNKI) from 1993~2022. The results showed that research on has gone through three stages: beginning (1993~2006), booming development (2007~2011), stable (2011-2022). focuses mainly pollution, control, model simulation. Agricultural always played a leading ...

In an effort to protect the quality of the water system, interest in non-point source pollution is increasing. Recently, studies of non-point sources pollution are continuing in relation to various land-use areas, but such studies have not been fully conducted in railway facility sites. Using monitoring data of railway bridge area with concrete road-bed, the runoff characteristics, pollutant un...

Urban non-point source pollution is becoming a serious issue under the context of rapid urbanization and its impacts on surface hydrologic processes. The identification risk areas effectiveness source-control measures provides important first steps to improve degrading aquatic environment but challenged by complex dynamics variabilities pollutants in urban environments. In this study, we invest...

The goal is to develop an inverse model capable of simultaneously estimating the parameters appearing in an air pollution model for an instantaneous point source, by using measured gas concentration data. The approach taken was to develop the inverse model as a non-linear least squares estimation problem in which the source term is estimated using measurements of pollution concentration on the ...

The agricultural non-point source (NPS) pollution caused by non-irrigated farming, such as heavy metals, nitrogen and phosphorus, has posed an extreme threat to the security of product quality watershed ecology. Thus, it is urgent sort out latest research progress future development trend effectively guide scientific technological updates in this field. This study integrates relevant literature...

1082-4006/06/1201-09$5.00 ©2006 The International Association of Chinese Professionals in Geographic Information Science (CPGIS) Abstract The U.S. Department of Agriculture developed the Agricultural Non-Point Source (AGNPS) pollution model. The AGNPS pollution model simulates the behavior of runoff, sediment, and nutrient transport from watersheds that have agriculture as their prime use. This...
