| 英文摘要 | Atmospheric phosphorus (P) deposition is an important component for understanding the dynamics of natural and semi-natural ecosystems. However, information about atmospheric P deposition is limited. Here, we show the long-term atmospheric P deposition at three forested sites, a suburban forest (S), rural forest (R1), and northern rural forest (R2) in Japan for 10 years from 2009 to 2018. Approximately 200 samples of bulk precipitation at each site were collected during the study period and total P (TP) was analyzed in addition to major ions. Annual TP deposition at sites S, R1, and R2 was 0.28 ± 0.06, 0.21 ± 0.05, and 0.12 ± 0.04 kg P ha−1 yr−1, respectively, and were large enough to affect P budgets in a forested watershed. Principal component analyses indicated that biogenic sources are the primary contributor to atmospheric P at rural forest sites, whereas anthropogenic sources may have a larger effect on atmospheric P at suburban forest site. Annual TP deposition at site S significantly decreased over the past decade. The significant relationship between annual TP deposition and annual nitrogen deposition at site S indicates that the decrease in TP deposition could be caused by a decrease in anthropogenic emissions. © 2019 Elsevier Ltd |
