真菌可以增加植物对氮素的吸收，影响土壤氮素循环。由于不同的树种在真菌类型，他们与林分尺度的土壤N循环可能会受到影响的树种组成，通过与不同类型的真菌。研究了亚热带森林中丛枝菌根（AM）和外生菌根（ECM）林对土壤氮循环的影响。土壤全氮和铵态氮（NH_4 ~+-N）含量在AM和ECM林间无显著差异，而可溶性有机氮（DON）和硝态氮（NO_3 ~--N）含量AM林显著高于ECM林（P
Mycorrhizae can enhance plant nitrogen ( N) acquisition and affect soil N cycling. Because tree species differ in mycorrhizae types they associated with, stand-scale soil N cycling could be influenced by tree species composition via their association with different types of mycorrhizae. We investigated the effects of arbuscular mycorrhizal ( AM) and ectomycorrhizal (ECM) forests on soil N cycling in subtropical forests. Total soil N and ammonium ( NH4+-N) contents did not differ between AM and ECM forests, whereas dissolved organic N ( DON) and nitrate (NO3--N) were significantly higher in AM than in ECM forests (P
