英文摘要	S has become the dominant contributor of acidic deposition globally, so we conducted a global overview on estimations of wet and dry S deposition patterns and then further analyzed coupling interactions between S and N cycling in this study. Results show that global average S wet deposition rate can reach 141.64 +/- 120.04 TgS.a(year)(-1), wherein the average S wet deposition rate of 84.5 +/- 79.31 TgS.a(-1) in Asia could result in a potential risk for soil acidification, contributing 59.7% to global wet S deposition. In comparison, the average S wet deposition flux in Europe is 18.51 +/- 16.06 kgS.ha(-1).a(-1), but North America and South America only have 8.16 +/- 4.12 and 4.96 +/- 3.45 kgS.ha(-1).a(-1), respectively. Moreover, the average S wet deposition rate in Europe and North America is only 18.81 +/- 16.32 TgS.a(-1) and 14.56 +/- 7.36 TgS.a(-1), respectively. Global average dry S deposition rate is estimated at 80.1 +/- 69.37 TgS.a(-1), wherein Asia contributes 58.3% of total global dry S deposition. However, the dry S deposition in Africa has reached 9.82 +/- 6.08 TgS.a(-1), and its contribution exceeds that of both Europe and South America. In addition, the elevated S emissions exhibit biochemical and physicochemical reactions with N under different interfaces. Therefore, the increases in N and S emissions will be important for future acidification levels. The coupling relationships of N and S under different interfaces will potentially reveal any new scientific issues that may arise and provide a better understanding of S and N cycling. Thus, distinguishing between N and S deposition, their sources, and associative critical loads could provide new insight into environmental effects and acid deposition estimations of greenhouse gases.
