Atmospheric nitrogen, phosphorus, and acid deposition in Chinese terrestrial ecosystems (2013)

It is also one of the main sources of nutrient and heavy metal input into natural terrestrial ecosystems. A systematic observation network of atmospheric wet deposition is helpful to quantify the deposition flux and explore the spatial-temporal pattern and influencing factors of wet deposition, which provides background references for ecological assessment.

Long-term in situ observation is one of the three basic tasks of the Chinese Ecosystem Research Network (CERN). In 2013, China Wet Deposition Observation Network (ChinaWD) was established based on CERN. ChinaWD has 54 observation sites now, whose scope covers the main ecosystem types of China.
