A database of annual atmospheric acid and nutrient deposition to China’s forests

Based
on a comprehensive literature review, here I present an updated database for
annual acid and nutrient deposition in China’s forests (CFAND 2.0). It includes
information from 56 forested sites on the water fluxes of bulk
precipitation and throughfall, the concentrations of H+ (pH), dissolved
inorganic N (NH4+-N and NO3--N),
S, dissolved P, K+, Ca2+ and Mg2+ in bulk precipitation
and throughfall, and the fluxes of dissolved inorganic N, S, dissolved P, K+,
Ca2+ and Mg2+ in bulk deposition and throughfall, as well
as geographical information and forest type.

本研究基于全面的文献调研，构建了中国森林酸沉降与养分沉降年度更新数据库（CFAND 2.0）。该数据库涵盖56个森林样点的相关数据，包括大气总降水（bulk precipitation）与穿透雨（throughfall）的水流通量，大气总降水和穿透雨中氢离子（H+，以pH值表征）、溶解态无机氮（dissolved inorganic N，包括NH4+-N与NO3--N）、硫（S）、溶解态磷（dissolved P）、钾离子（K+）、钙离子（Ca2+）及镁离子（Mg2+）的浓度，以及总沉降（bulk deposition）与穿透雨中溶解态无机氮、硫、溶解态磷、钾离子、钙离子及镁离子的沉降通量，同时包含样点的地理信息与森林类型。
