Abstract:: Nitrogen deposition has an important influence on hot-water extractable organic matter in rhizosphere and non-rhizosphere of Pinus tabulaeformis in the Loess Plateau. Pot experiments of Pinus tabulaeformis were continuously cultured for six years, with adding six nitrogen gradients [0, 2.8, 5.6, 11.2, 22.4 and 44.8 g/(m²·a)]. With respect to hot-water extractable organic matter (hot-water extractable organic carbon, HWOC; hot-water extractable organic nitrogen, HWON) in rhizosphere and non-rhizosphere of Pinus tabulaeformis, nitrogen deposition content with less than 5.6 g/(m²·a) markedly increased HWOC. Nitrogen deposition content with more than or equal to 5.6 g/(m²·a) did not significantly affect HWOC. HWTN (hot-water extractable total nitrogen), HWON, HWON/HWTN, HWTN/TN (total nitrogen) and HWON/TN increased with increase of nitrogen deposition content. There were remarkable differences between rhizosphere and non-rhizosphere situations. Nitrogen deposition increased aromatic compounds and carboxyl content by UV characteristic values. A certain level of nitrogen deposition would decompose easy-decomposable components of hot-water extractable organic matter. Under a certain range of low nitrogen deposition, hot water extractable organic matter in rhizosphere increased, which is different from that in non-rhizosphere. Functional group contents of hot water extract organic matter could be changed, but the changes were not consistent. Two indicators may permit to indicate metabolic type response differences for nitrogen deposition. One is SUVA254 and E280 (associated with ammonia nitrogen, another is ASI (associated with nitrate nitrogen).
