| 英文摘要 | Acid deposition in precipitation has received widespread attention. however, it is necessary to monitor the acid deposition in chinese agricultural and natural ecosystems because data derived from traditional urban/suburban observations might overestimate it to some extent. in this study, we continuously measured the acid deposition through precipitation (ph, sulfate (so42-), and nitrate (no3-)) in 43 field stations from 2009 to 2014 to explore the spatial patterns and the main influencing factors of acid deposition in chinese agricultural and natural ecosystems. the results showed that the average precipitation ph at the 43 stations varied between 4.10 and 8.25 (average: 6.2) with nearly 20% of the observation sites being subjected to acid precipitation (ph<5.6). the average deposition of so42- and no3- was 115.99 and 32.93kgha(-1)yr(-1), respectively. an apparent regional difference of acid deposition in chinese agricultural and natural ecosystems was observed, which was most serious in south and central china and less serious in northwest china, inner mongolia, and qinghai-tibet. the level of economic development and amount of precipitation could explain most of the spatial variations of ph, so42-, and no3- depositions. it is anticipated that acid deposition might increase further, although the current level of acid deposition in these chinese agricultural and natural ecosystems was found to be less serious than projected from urban/suburban data. the control of energy consumption should be strengthened in future to prevent an increase of acid deposition in china. |
