摘要:... The existing runoff and erosion models focus on estimating the total amount of pollutants in the long term. There are few studies on the process of nutrient transport during individual rainfall events, and there are still some shortcomings in the mathematical models that desc...

摘要:Abstract(#br)The increase of nutrient loads such as nitrogen and phosphorus to a river due to land cover changes in surrounding areas has been one of the major sources of water pollution or eutrophication. Monitoring the influent nutrient load from river basins to rivers is now c...

摘要:Abstract(#br)Numerous studies have addressed the effects of forest conversion on soil organic carbon (SOC) and total nitrogen (TN); however, knowledge of SOC and TN stocks and SOC stability after primary forest conversion to secondary forest is still lacking. Such an underst...

摘要:... Cultivation on regosol is extensive and total nitrogen (TN) has become a common NPS pollutant. Artificial rainfall experiments were conducted to reveal the influence mechanisms of rainfall and terrain on TN losses from regosol. The results showed that there were positive co...
