XU Qin-xiang~1;PANG Jiang-li~1;HUANG Chun-chang ~(1, 2) (1.Northwest Research Center for Historical Environment and Socio-economic Development, Coll.Tourism & Envmt.Sci.,Shaanxi Normal Univ., Xi'an 710062, Shaanxi, China; 2.State Key Laboratory of Soil Erosion and Dryland Farming on Loess Plateau, Yangling 712100, Shaanxi, China)  
The total content as a climatic proxy is often used in studying of lake and sea deposition condition but hardly used in the Holocene loess-soil sequence on the Loess Plateau. Based on particular survey in the field, LGT Holocene profile in the Eastern Guanzhong basin, Shaanxi, China is selected and total nitrogen content and magnetic susceptibility are measured. The studied results show that total nitrogen content is 0.294 0 g/kg in loess,and 0.385 6 g/kg in soil. What is more, total nitrogen content appears high-low superseded change in the loess profile. At 0~40 cm, 96~196 cm, 210~274 cm, the profile show three high values, corresponding respectively TS, S~1_0, S~2_0,at 40~96 cm, 196~210 cm, 274 ~380 cm appear three low values, corresponding respectively L_0, L_x, L_1. The change of total nitrogen content is in correspondence with magnetic susceptibility curve and the loess-soil sequence. So total nitrogen is offspring of the special climate condition, the content and the distribution is in reference to climate condition. So total nitrogen can be a climatic proxy that recover palaeoclimate. High total nitrogen content shows warm-humid climatic environment, whereas low total nitrogen content shows cold-dry climatic environment.
