Environmental hydrogen and oxygen isotopes are ideal tracers of water, as they are incorporated in the water molecules and their behaviours and variations reflect the origin of, and the hydrological and geochemical processes undergone by, natural water bodies. Water vapor source is always one of the important topics in geosciences. It is more important scientific and practical significance to carry out the identification of interaction region influenced by the low latitude water vapor channels in China, especially under the background of the global climate system changing in recent years. This paper regards the interaction region influenced possibly by both Southwest Moisture and South Sea Moisture as the research target, by means of stable isotope ratio mass spectrometer MAT253 measuring the content of hydrogen and oxygen stable isotopes of 239 effective samples at 16 samples atmospheric precipitation from April to October of 2014 in Yunnan Province and Guangxi Zhuang Autonomous Region between 23-24°N. We have achieved spatial pattern of δD and δ18O based on ArcGIS13.0 software by trend analysis, and demarcated boundaries between the moisture from Southwest and the moisture from South Sea. There are three main results. Firstly, spatial patterns of both δD and δ18O are consistent basically both in the whole rainy season precipitation and a rainfall process. Secondly, both rainfall factor and continental factor have affected the spatial pattern of hydrogen and oxygen stable isotopes in atmospheric precipitation. Thirdly, Southwest vapor met the South Sea vapor nearby points among Honghe, Gejiu and Meingzi, in the whole rainy season precipitation or a rainfall process. So the zone among points of Honghe, Gejiu and Mengzi is probably the region, in which both Southwest vapor and South Sea vapor interact on each other.
