A database for annual atmospheric acid and nutrient deposition in China’s forests

Based on a comprehensive literature review, here I present an updated database for acid and nutrient deposition in China’s forests (CFAND 2.0). It includes detailed information from 56 forested sites on water fluxes of bulk precipitation and throughfall, 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 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综述，构建了中国森林酸沉降与养分沉降更新版数据库（CFAND 2.0）。该数据库涵盖56个森林样点的详细监测数据，包括总降水与穿透雨的水通量；总降水和穿透雨中的氢离子浓度（以pH值表征）、溶解态无机氮（NH4+-N与NO3--N）、硫（S）、溶解态磷、钾离子（K+）、钙离子（Ca2+）及镁离子（Mg2+）浓度；总沉降与穿透雨中的溶解态无机氮、硫、溶解态磷、钾离子、钙离子及镁离子的通量；同时包含样点的地理信息与森林类型信息。
