氮沉降对杉木人工林土壤化学计量特征的影响
Effects of N Deposition on Soil Stoichiometric Characteristics of Chinese fir Plantation
摘要
Abstract
Taking the simulated nitrogen deposition experiment field in a Chinese fir plantation Shaxian Guanzhuang State Forest Farm of Fujian Province as the researched object,this paper studied the responses of soil carbon,nitrogen,phosphorus and their sto-chiometric characteristics on nitrogen deposition.Which were 0,60,120 and 240 kg· hm-2 · a-1.The continuous 7-year-long exper-iment results showed that the simulated nitrogen deposition did not effect evidently on the soil carbon content,but increased soil ni-trogen concentration and ratios of N:P and decreased concentrations of soil phosphorus.The responses of stochiometric characteristics were mainly focused in the upper soil layer,which indicated that more attention should be paid to the upper soil biogeochemical cycle research in order to appropriately assess the effects of ecosystem on nitrogen deposition.关键词
