Description :
Based on 7 CHNIP (Chinese Network of Isotopes in Precipitation) observary stations located in southern China, monthly composite precipitation samples have been collected and analyzed for the composition of δ O 18 during July, 2005. The results indicated that the spatial distributions of δ O 18 in precipitation could properly portray the moisture sources together with their transport pathways. Moreover, the amount effect, altitude effect, temperature effect and the correlation between δ O 18 vs. relative humidity were discussed.
