Abstract:
The effects of nitrogen (N) transformation and transportation processes under different soil pH, plant species and rainfall intervals were studied by using a 15N isotope tracing technique in a simulated grassed paving system. The results showed that the grassed paving systems with three plants including Zoysia matrella (Z), Eleusine indica (E) and Liriope graminifolia (L), were effective at removing NH4 +-N, NO3 --N, total nitrogen (TN), and chemical oxygen demand (COD) from rainfall runoff. However, there was no significant difference of TN removal among these three-plant species and a certain soil pH. The experiment showed that when the rainfall interval was 5 days, the grassed paving system could remove 65.8-76.8% of runoff TN in 17 detention days. The N conversion was dominated by soil adsorption, plant uptake, microbial assimilation, and nitrification during 0-5 d. While the main N reactions were through denitrification and dissimilatory nitrate reduction to ammonium during 5-14 d.
