氮磷添加下典型温带、亚热带森林土壤氮循环功能基因丰度和微生物群落属性数据集

氮循环功能基因丰度和氮循环微生物群落性质的数据集基于中国生态系统研究网络森林中的氮磷添加野外试验平台创建。我们测定和收集了我国东部典型温带（长白山）和亚热带森林（鼎湖山和千烟洲）氮磷添加样地表层土和无氮磷添加样地沿垂直剖面的土壤中的氮循环功能基因丰度、群落多样性、群落组成和氮循环微生物活性，以及土壤理化性质。本数据集由2475条氮循环微生物性质数据和684条土壤理化性质数据组成。数据集包括生物固氮、有机氮分解、硝化和反硝化四个微生物过程和氨氧化古菌amoA、氨氧化细菌amoA、nirK、nirS、nosZ、qnorB、narG、nir、nifH和chiA十个氮循环功能基因，以及土壤pH、含水量和有机碳、NH4+、 NO3−、有效磷、总氮、总碳、总磷和溶解性有机碳浓度和N2O的排放、净硝化速率。

This dataset focuses on the abundance of nitrogen cycle functional genes and properties of nitrogen-cycle microbial communities, and was established based on field experimental platforms for nitrogen and phosphorus addition in forests under the Chinese Ecosystem Research Network (CERN).

We measured and collected data on the abundance of nitrogen cycle functional genes, community diversity, community composition, nitrogen-cycle microbial activities, and soil physicochemical properties from topsoil samples collected along vertical profiles in both nitrogen and phosphorus addition plots and control plots (without nitrogen and phosphorus addition) in the typical temperate forest (Changbai Mountain) and subtropical forests (Dinghushan and Qianyanzhou) of eastern China.

This dataset comprises 2475 entries of nitrogen-cycle microbial property data and 684 entries of soil physicochemical property data. It covers four microbial processes: biological nitrogen fixation, organic nitrogen decomposition, nitrification, and denitrification; ten nitrogen cycle functional genes: ammonia-oxidizing archaea amoA, ammonia-oxidizing bacteria amoA, nirK, nirS, nosZ, qnorB, narG, nir, nifH, and chiA; and multiple soil properties including pH, water content, concentrations of organic carbon, NH4+, NO3−, available phosphorus, total nitrogen, total carbon, total phosphorus, dissolved organic carbon, as well as N2O emission and net nitrification rate.
